153-466: Tyre ( / ˈ t aɪər / ; Arabic : صُور , romanized :  Ṣūr ; Phoenician : 𐤑𐤓 , romanized:  Ṣūr ; Hebrew : צוֹר , romanized :  Tsur ; ‹See Tfd› Greek : Τύρος , translit.   Týros ) is a city in Lebanon , one of the oldest continuously inhabited cities in the world, though in medieval times for some centuries by just a small population. It

306-734: A Central Semitic language of the Afroasiatic language family spoken primarily in the Arab world . The ISO assigns language codes to 32 varieties of Arabic , including its standard form of Literary Arabic, known as Modern Standard Arabic , which is derived from Classical Arabic . This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as al-ʿarabiyyatu l-fuṣḥā ( اَلعَرَبِيَّةُ ٱلْفُصْحَىٰ "the eloquent Arabic") or simply al-fuṣḥā ( اَلْفُصْحَىٰ ). Arabic

459-575: A collection of related dialects that constitute the precursor of Arabic, first emerged during the Iron Age . Previously, the earliest attestation of Old Arabic was thought to be a single 1st century CE inscription in Sabaic script at Qaryat al-Faw , in southern present-day Saudi Arabia. However, this inscription does not participate in several of the key innovations of the Arabic language group, such as

612-414: A concept of physiographic regions while a conflicting trend among geographers was to equate physiography with "pure morphology", separated from its geological heritage. In the period following World War II, the emergence of process, climatic, and quantitative studies led to a preference by many earth scientists for the term "geomorphology" in order to suggest an analytical approach to landscapes rather than

765-435: A corpus of poetic texts, in addition to Qur'an usage and Bedouin informants whom he considered to be reliable speakers of the ʿarabiyya . Arabic spread with the spread of Islam . Following the early Muslim conquests , Arabic gained vocabulary from Middle Persian and Turkish . In the early Abbasid period , many Classical Greek terms entered Arabic through translations carried out at Baghdad's House of Wisdom . By

918-491: A decline in the popularity of climatic geomorphology in the late 20th century. Stoddart criticized climatic geomorphology for applying supposedly "trivial" methodologies in establishing landform differences between morphoclimatic zones, being linked to Davisian geomorphology and by allegedly neglecting the fact that physical laws governing processes are the same across the globe. In addition some conceptions of climatic geomorphology, like that which holds that chemical weathering

1071-438: A descriptive one. During the age of New Imperialism in the late 19th century European explorers and scientists traveled across the globe bringing descriptions of landscapes and landforms. As geographical knowledge increased over time these observations were systematized in a search for regional patterns. Climate emerged thus as prime factor for explaining landform distribution at a grand scale. The rise of climatic geomorphology

1224-1081: A dialect of Arabic and written in the Latin alphabet . The Balkan languages, including Albanian, Greek , Serbo-Croatian, and Bulgarian , have also acquired many words of Arabic origin, mainly through direct contact with Ottoman Turkish . Arabic has influenced languages across the globe throughout its history, especially languages where Islam is the predominant religion and in countries that were conquered by Muslims. The most markedly influenced languages are Persian , Turkish , Hindustani ( Hindi and Urdu ), Kashmiri , Kurdish , Bosnian , Kazakh , Bengali , Malay ( Indonesian and Malaysian ), Maldivian , Pashto , Punjabi , Albanian , Armenian , Azerbaijani , Sicilian, Spanish, Greek, Bulgarian, Tagalog , Sindhi , Odia , Hebrew and African languages such as Hausa , Amharic , Tigrinya , Somali , Tamazight , and Swahili . Conversely, Arabic has borrowed some words (mostly nouns) from other languages, including its sister-language Aramaic, Persian, Greek, and Latin and to

1377-574: A fictional dialogue where the immortal Magu explained that the territory of the East China Sea was once a land filled with mulberry trees . The term geomorphology seems to have been first used by Laumann in an 1858 work written in German. Keith Tinkler has suggested that the word came into general use in English, German and French after John Wesley Powell and W. J. McGee used it during

1530-580: A fisherman by profession, who was also a traditional storyteller ( hakawati ) and thus interested in cinema – projected films on the wall of a Turkish hammam. In 1939 the Roxy opened, followed in 1942 by the "Empire": By the mid-1950s there were four cinemas in Tyre, and four more soon opened in nearby Nabatieh . Many also hosted live performances by famous actors and musicians, serving as community spaces where people from different backgrounds came together. In 1959,

1683-652: A halt after 2012 due to the war there, some of them instead started excavations in Tyre, amongst them a team headed by Leila Badre , director of the Archeological Museum of the American University of Beirut ( AUB ), and Belgian archaeologists. Threats to Tyre's ancient cultural heritage include development pressures and the illegal antiquities trade. A highway, planned for 2011, was expected to be built in areas that are deemed archaeologically sensitive. A small-scale geophysical survey indicated

1836-487: A lesser extent and more recently from Turkish, English, French, and Italian. Arabic is spoken by as many as 380 million speakers, both native and non-native, in the Arab world, making it the fifth most spoken language in the world, and the fourth most used language on the internet in terms of users. It also serves as the liturgical language of more than 2 billion Muslims . In 2011, Bloomberg Businessweek ranked Arabic

1989-606: A major impact on the development of Lebanese music: Halim el-Roumi (1919–1983) and Ghazi Kahwaji (1945–2017). Some sources claim that the famous musician, composer, singer and actor el-Roumi was born in Tyre to Lebanese parents. However, others suggest that he was born in Nazareth and moved to Tyre from Palestine. For some time, he worked as a teacher at the Jafariya High School there. In 1950 he became director of Radio Lebanon 's music department, where he discovered

2142-690: A millennium before the modern period . Early lexicographers ( لُغَوِيُّون lughawiyyūn ) sought to explain words in the Quran that were unfamiliar or had a particular contextual meaning, and to identify words of non-Arabic origin that appear in the Quran. They gathered shawāhid ( شَوَاهِد 'instances of attested usage') from poetry and the speech of the Arabs—particularly the Bedouin ʾaʿrāb  [ ar ] ( أَعْراب ) who were perceived to speak

2295-435: A mountain belt to promote further erosion as mass is removed from the chain and the belt uplifts. Long-term plate tectonic dynamics give rise to orogenic belts , large mountain chains with typical lifetimes of many tens of millions of years, which form focal points for high rates of fluvial and hillslope processes and thus long-term sediment production. Features of deeper mantle dynamics such as plumes and delamination of

2448-594: A result, many European languages have borrowed words from it. Arabic influence, mainly in vocabulary, is seen in European languages (mainly Spanish and to a lesser extent Portuguese , Catalan , and Sicilian ) owing to the proximity of Europe and the long-lasting Arabic cultural and linguistic presence, mainly in Southern Iberia, during the Al-Andalus era. Maltese is a Semitic language developed from

2601-474: A sanctuary for sea turtles and migrating birds. Due to its diverse flora and fauna , the reserve was designated a Ramsar Site in 1999 according to the international treaty for the conservation and sustainable use of Wetlands , since it is considered "the last bio-geographic ecosystem in Lebanon". It is an important nesting site for migratory birds , the endangered Loggerhead and green sea turtle ,

2754-462: A script derived from ASA attest to a language known as Hasaitic . On the northwestern frontier of Arabia, various languages known to scholars as Thamudic B , Thamudic D, Safaitic , and Hismaic are attested. The last two share important isoglosses with later forms of Arabic, leading scholars to theorize that Safaitic and Hismaic are early forms of Arabic and that they should be considered Old Arabic . Linguists generally believe that "Old Arabic",

2907-470: A single language, despite mutual incomprehensibility among differing spoken versions. From a linguistic standpoint, it is often said that the various spoken varieties of Arabic differ among each other collectively about as much as the Romance languages . This is an apt comparison in a number of ways. The period of divergence from a single spoken form is similar—perhaps 1500 years for Arabic, 2000 years for

3060-489: A stretch of 2 km with agriculture lands of small family farms and the springs of Ras El Ain with three constantly flowing artesian wells , ranging from Rashidieh to the village of Chaetiyeh in the South. The former is divided into two zones: one for tourism that features a public beach of some 900 m and restaurant tents during the summer season hosting up to 20,000 visitors on a busy day, and another 900 m of conservation zone as

3213-507: A type of Arabic. Cypriot Arabic is recognized as a minority language in Cyprus. The sociolinguistic situation of Arabic in modern times provides a prime example of the linguistic phenomenon of diglossia , which is the normal use of two separate varieties of the same language, usually in different social situations. Tawleed is the process of giving a new shade of meaning to an old classical word. For example, al-hatif lexicographically means

3366-490: A valley causes abrasion and plucking of the underlying rock . Abrasion produces fine sediment, termed glacial flour . The debris transported by the glacier, when the glacier recedes, is termed a moraine . Glacial erosion is responsible for U-shaped valleys, as opposed to the V-shaped valleys of fluvial origin. The way glacial processes interact with other landscape elements, particularly hillslope and fluvial processes,

3519-507: A variety of regional vernacular Arabic dialects , which are not necessarily mutually intelligible. Classical Arabic is the language found in the Quran , used from the period of Pre-Islamic Arabia to that of the Abbasid Caliphate . Classical Arabic is prescriptive, according to the syntactic and grammatical norms laid down by classical grammarians (such as Sibawayh ) and the vocabulary defined in classical dictionaries (such as

3672-659: A very brief outline of some of the major figures and events in its development. The study of landforms and the evolution of the Earth's surface can be dated back to scholars of Classical Greece . In the 5th century BC, Greek historian Herodotus argued from observations of soils that the Nile delta was actively growing into the Mediterranean Sea , and estimated its age. In the 4th century BC, Greek philosopher Aristotle speculated that due to sediment transport into

3825-476: A wider audience." In the wake of the industrial revolution and European hegemony and colonialism , pioneering Arabic presses, such as the Amiri Press established by Muhammad Ali (1819), dramatically changed the diffusion and consumption of Arabic literature and publications. Rifa'a al-Tahtawi proposed the establishment of Madrasat al-Alsun in 1836 and led a translation campaign that highlighted

3978-590: Is a minimum level of comprehension between all Arabic dialects, this level can increase or decrease based on geographic proximity: for example, Levantine and Gulf speakers understand each other much better than they do speakers from the Maghreb. The issue of diglossia between spoken and written language is a complicating factor: A single written form, differing sharply from any of the spoken varieties learned natively, unites several sometimes divergent spoken forms. For political reasons, Arabs mostly assert that they all speak

4131-559: Is a sister language rather than their direct ancestor. Arabia had a wide variety of Semitic languages in antiquity. The term "Arab" was initially used to describe those living in the Arabian Peninsula , as perceived by geographers from ancient Greece . In the southwest, various Central Semitic languages both belonging to and outside the Ancient South Arabian family (e.g. Southern Thamudic) were spoken. It

4284-603: Is an important aspect of Plio-Pleistocene landscape evolution and its sedimentary record in many high mountain environments. Environments that have been relatively recently glaciated but are no longer may still show elevated landscape change rates compared to those that have never been glaciated. Nonglacial geomorphic processes which nevertheless have been conditioned by past glaciation are termed paraglacial processes. This concept contrasts with periglacial processes, which are directly driven by formation or melting of ice or frost. Soil , regolith , and rock move downslope under

4437-478: Is believed that the ancestors of the Modern South Arabian languages (non-Central Semitic languages) were spoken in southern Arabia at this time. To the north, in the oases of northern Hejaz , Dadanitic and Taymanitic held some prestige as inscriptional languages. In Najd and parts of western Arabia, a language known to scholars as Thamudic C is attested. In eastern Arabia, inscriptions in

4590-861: Is close to the Roum Fault and the Yammouneh Fault . Though it has suffered a number of devastating earthquakes over the millennia , the threat level is considered to be low in most places and moderate in a few others. However, a tsunami following an earthquake and subsequent landslides and floods pose major natural risks to the Tyrian population. Vast reserves of natural gas are estimated to lie beneath Lebanese waters, much of it off Tyre's coast, but exploitation has been delayed by border disputes with Israel. Early names of Tyre include Akkadian Ṣurru , Phoenician Ṣūr ( 𐤑𐤓 ‎ ), and Hebrew Tsur ( צוֹר ). In Semitic languages ,

4743-408: Is credited with establishing the rules of Arabic prosody . Al-Jahiz (776–868) proposed to Al-Akhfash al-Akbar an overhaul of the grammar of Arabic, but it would not come to pass for two centuries. The standardization of Arabic reached completion around the end of the 8th century. The first comprehensive description of the ʿarabiyya "Arabic", Sībawayhi's al - Kitāb , is based first of all upon

4896-472: Is credited with standardizing Arabic grammar , or an-naḥw ( النَّحو "the way" ), and pioneering a system of diacritics to differentiate consonants ( نقط الإعجام nuqaṭu‿l-i'jām "pointing for non-Arabs") and indicate vocalization ( التشكيل at-tashkīl ). Al-Khalil ibn Ahmad al-Farahidi (718–786) compiled the first Arabic dictionary, Kitāb al-'Ayn ( كتاب العين "The Book of the Letter ع "), and

5049-699: Is extremely important in sedimentology . Weathering is the chemical and physical disruption of earth materials in place on exposure to atmospheric or near surface agents, and is typically studied by soil scientists and environmental chemists , but is an essential component of geomorphology because it is what provides the material that can be moved in the first place. Civil and environmental engineers are concerned with erosion and sediment transport, especially related to canals , slope stability (and natural hazards ), water quality , coastal environmental management, transport of contaminants, and stream restoration . Glaciers can cause extensive erosion and deposition in

5202-420: Is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence , and shape the coastal geography . Surface processes comprise the action of water, wind, ice, wildfire , and life on the surface of the Earth, along with chemical reactions that form soils and alter material properties, the stability and rate of change of topography under

5355-611: Is more rapid in tropical climates than in cold climates proved to not be straightforwardly true. Geomorphology was started to be put on a solid quantitative footing in the middle of the 20th century. Following the early work of Grove Karl Gilbert around the turn of the 20th century, a group of mainly American natural scientists, geologists and hydraulic engineers including William Walden Rubey , Ralph Alger Bagnold , Hans Albert Einstein , Frank Ahnert , John Hack , Luna Leopold , A. Shields , Thomas Maddock , Arthur Strahler , Stanley Schumm , and Ronald Shreve began to research

5508-574: Is not present in the spoken varieties, but deletes Classical words that sound obsolete in MSA. In addition, MSA has borrowed or coined many terms for concepts that did not exist in Quranic times, and MSA continues to evolve. Some words have been borrowed from other languages—notice that transliteration mainly indicates spelling and not real pronunciation (e.g., فِلْم film 'film' or ديمقراطية dīmuqrāṭiyyah 'democracy'). The current preference

5661-855: Is official in Mali and recognized as a minority language in Morocco, while the Senegalese government adopted the Latin script to write it. Maltese is official in (predominantly Catholic ) Malta and written with the Latin script . Linguists agree that it is a variety of spoken Arabic, descended from Siculo-Arabic , though it has experienced extensive changes as a result of sustained and intensive contact with Italo-Romance varieties, and more recently also with English. Due to "a mix of social, cultural, historical, political, and indeed linguistic factors", many Maltese people today consider their language Semitic but not

5814-444: Is probably of profound importance for the terrestrial geomorphic system as a whole. Biology can influence very many geomorphic processes, ranging from biogeochemical processes controlling chemical weathering , to the influence of mechanical processes like burrowing and tree throw on soil development, to even controlling global erosion rates through modulation of climate through carbon dioxide balance. Terrestrial landscapes in which

5967-415: Is since the 1990s no longer accepted by mainstream scholarship as a basis for geomorphological studies. Albeit having its importance diminished, climatic geomorphology continues to exist as field of study producing relevant research. More recently concerns over global warming have led to a renewed interest in the field. Despite considerable criticism, the cycle of erosion model has remained part of

6120-572: Is the third most widespread official language after English and French, one of six official languages of the United Nations , and the liturgical language of Islam . Arabic is widely taught in schools and universities around the world and is used to varying degrees in workplaces, governments and the media. During the Middle Ages , Arabic was a major vehicle of culture and learning, especially in science, mathematics and philosophy. As

6426-590: Is the variety used in most current, printed Arabic publications, spoken by some of the Arabic media across North Africa and the Middle East, and understood by most educated Arabic speakers. "Literary Arabic" and "Standard Arabic" ( فُصْحَى fuṣḥá ) are less strictly defined terms that may refer to Modern Standard Arabic or Classical Arabic. Some of the differences between Classical Arabic (CA) and Modern Standard Arabic (MSA) are as follows: MSA uses much Classical vocabulary (e.g., dhahaba 'to go') that

The Tyrian municipality of Ain Baal is apparently also named after the Phoenician deity. The most visible part of ancient and medieval history on the other side have been the archaeological sites though: The first archaeological excavations were by Ernest Renan in 1860 and 1861. He

6885-524: Is used to denote concepts that have arisen in the industrial and post-industrial era , especially in modern times. Due to its grounding in Classical Arabic, Modern Standard Arabic is removed over a millennium from everyday speech, which is construed as a multitude of dialects of this language. These dialects and Modern Standard Arabic are described by some scholars as not mutually comprehensible. The former are usually acquired in families, while

However, it has discarded some grammatical constructions and vocabulary that no longer have any counterpart in the spoken varieties and has adopted certain new constructions and vocabulary from the spoken varieties. Much of the new vocabulary

The following features of Proto-Arabic can be reconstructed with confidence: On the other hand, several Arabic varieties are closer to other Semitic languages and maintain features not found in Classical Arabic, indicating that these varieties cannot have developed from Classical Arabic. Thus, Arabic vernaculars do not descend from Classical Arabic: Classical Arabic

According to UNIFIL , it was visited "by celebrity who's whos of the time, including Jean Marais , Brigitte Bardot , Rushdi Abaza and Omar Hariri." In 1964, the "Dunia" opened, two years later followed by the "Al Hamra Cinema", which became a venue for some of the Arab world's most famous performers, like Mahmoud Darwish , Sheikh Imam , Ahmed Fouad Negm , Wadih el-Safi , and Marcel Khalife . Meanwhile, two Tyrian artists had

8262-419: The "learned" tradition (Classical Arabic). This variety and both its classicizing and "lay" iterations have been termed Middle Arabic in the past, but they are thought to continue an Old Higazi register. It is clear that the orthography of the Quran was not developed for the standardized form of Classical Arabic; rather, it shows the attempt on the part of writers to record an archaic form of Old Higazi. In

8415-723: The "purest," most eloquent form of Arabic—initiating a process of jamʿu‿l-luɣah ( جمع اللغة 'compiling the language') which took place over the 8th and early 9th centuries. Kitāb al-'Ayn ( c.  8th century ), attributed to Al-Khalil ibn Ahmad al-Farahidi , is considered the first lexicon to include all Arabic roots ; it sought to exhaust all possible root permutations —later called taqālīb ( تقاليب ) — calling those that are actually used mustaʿmal ( مستعمَل ) and those that are not used muhmal ( مُهمَل ).

For example, Maimonides , the Andalusi Jewish philosopher, authored works in Judeo-Arabic —Arabic written in Hebrew script . Ibn Jinni of Mosul , a pioneer in phonology , wrote prolifically in the 10th century on Arabic morphology and phonology in works such as Kitāb Al-Munṣif , Kitāb Al-Muḥtasab , and Kitāb Al-Khaṣāʾiṣ    [ ar ] .

Denudation of these high uplifted regions produces sediment that is transported and deposited elsewhere within the landscape or off the coast. On progressively smaller scales, similar ideas apply, where individual landforms evolve in response to the balance of additive processes (uplift and deposition) and subtractive processes ( subsidence and erosion ). Often, these processes directly affect each other: ice sheets, water, and sediment are all loads that change topography through flexural isostasy . Topography can modify

Both volcanic (eruptive) and plutonic (intrusive) igneous processes can have important impacts on geomorphology. The action of volcanoes tends to rejuvenize landscapes, covering the old land surface with lava and tephra , releasing pyroclastic material and forcing rivers through new paths. The cones built by eruptions also build substantial new topography, which can be acted upon by other surface processes. Plutonic rocks intruding then solidifying at depth can cause both uplift or subsidence of

Participants could purchase tickets for 100 euros to win

10710-690: The Qur'an is referred to by linguists as "Quranic Arabic", as distinct from its codification soon thereafter into " Classical Arabic ". In late pre-Islamic times, a transdialectal and transcommunal variety of Arabic emerged in the Hejaz , which continued living its parallel life after literary Arabic had been institutionally standardized in the 2nd and 3rd century of the Hijra , most strongly in Judeo-Christian texts, keeping alive ancient features eliminated from

Also, while it is comprehensible to people from the Maghreb , a linguistically innovative variety such as Moroccan Arabic is essentially incomprehensible to Arabs from the Mashriq , much as French is incomprehensible to Spanish or Italian speakers but relatively easily learned by them. This suggests that the spoken varieties may linguistically be considered separate languages. With

11016-552: The South. In addition, there are the springs of Al Bagbog and Ain Ebreen in the North as well as the Litani River , also known as Alqasymieh. The present city of Tyre covers a large part of the original island and has expanded onto and covers most of the causeway built by Alexander the Great in 332 BCE . This isthmus increased greatly in width over the centuries because of extensive silt depositions on either side. The part of

11169-469: The armed conflict and by anarchic urban development. In the late 1980s, "clandestine excavations" took place in the Al-Bass cemetery , which "flooded the antiquities market". Regular excavation activities only started again in 1995 under the supervision of Ali Khalil Badawi. Shortly afterwards, an Israeli bomb destroyed an apartment block in the city and evidence for an early church was revealed underneath

11322-441: The availability of sediment itself and on the river's discharge . Rivers are also capable of eroding into rock and forming new sediment, both from their own beds and also by coupling to the surrounding hillslopes. In this way, rivers are thought of as setting the base level for large-scale landscape evolution in nonglacial environments. Rivers are key links in the connectivity of different landscape elements. As rivers flow across

11475-598: The biodiversity of the TCNR is threatened as shown by a strong decrease in the numbers of the caspian terrapin Mauremys caspica , the green toad Bufo viridis and the tree frog Hyla savigny . Also, since the 2000s, the North American camphorweed Heterotheca subaxillaris has invaded the TCNR as a neophyte from Haifa across the Blue Line. During the 2006 war, turtle breeding areas were affected when

11628-680: The bombardment had damaged frescoes in a Roman funerary cave at the Tyre Necropolis . Additional site degradation was also noted, including "the lack of maintenance, the decay of exposed structures due to lack of rainwater regulation and the decay of porous and soft stones". Since 2008, a Lebanese French team under the direction by Pierre-Louis Gatier of the University of Lyon has been conducting archaeological and topographical work. When international archeological missions in Syria came to

11781-425: The causeway, rapidly creating an emerged sandy isthmus (or tombolo ), linking the island to the mainland. This sandy isthmus rapidly inflated during the centuries following the construction of the causeway. By early Imperial Roman times, monumental buildings had been built over most of its surface. Their layout implies that the isthmus was by then nearly as wide as today. Therefore, the isthmus had completely reshaped

11934-539: The centuries. He inferred that the land was reshaped and formed by soil erosion of the mountains and by deposition of silt , after observing strange natural erosions of the Taihang Mountains and the Yandang Mountain near Wenzhou . Furthermore, he promoted the theory of gradual climate change over centuries of time once ancient petrified bamboos were found to be preserved underground in

12087-473: The coast of the Mediterranean Sea , and is located about 80 km (50 mi) south of Beirut . It originally consisted of two distinct urban centres: Tyre itself, which was on an island just 500 to 700m offshore, and the associated settlement of Ushu on the adjacent mainland, later called Palaetyrus , meaning "Old Tyre" in Ancient Greek . The fortified city was on top of a rock from which its name

12240-574: The conversion of Semitic mimation to nunation in the singular. It is best reassessed as a separate language on the Central Semitic dialect continuum. It was also thought that Old Arabic coexisted alongside—and then gradually displaced— epigraphic Ancient North Arabian (ANA), which was theorized to have been the regional tongue for many centuries. ANA, despite its name, was considered a very distinct language, and mutually unintelligible, from "Arabic". Scholars named its variant dialects after

12393-457: The cycle over. In the decades following Davis's development of this idea, many of those studying geomorphology sought to fit their findings into this framework, known today as "Davisian". Davis's ideas are of historical importance, but have been largely superseded today, mainly due to their lack of predictive power and qualitative nature. In the 1920s, Walther Penck developed an alternative model to Davis's. Penck thought that landform evolution

12546-448: The discovery of 250 BCE to 500 CE harbour sediments behind this breakwater demonstrated the existence of a northern harbour repeatedly, if not permanently, throughout Antiquity under the modern harbour of Tyre. The location of the southern harbour is more elusive. Renan (1864–1874) envisioned it as an extensive structure now located offshore, south of the former island. Subsequent diving surveys identified submerged man-made structures on

12699-571: The dry, northern climate zone of Yanzhou , which is now modern day Yan'an , Shaanxi province. Previous Chinese authors also presented ideas about changing landforms. Scholar-official Du Yu (222–285) of the Western Jin dynasty predicted that two monumental stelae recording his achievements, one buried at the foot of a mountain and the other erected at the top, would eventually change their relative positions over time as would hills and valleys. Daoist alchemist Ge Hong (284–364) created

12852-413: The early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a contraction of " physi cal" and "ge ography ", and therefore synonymous with physical geography , and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline. Some geomorphologists held to a geological basis for physiography and emphasized

13005-495: The early 19th century, authors – especially in Europe – had tended to attribute the form of landscapes to local climate , and in particular to the specific effects of glaciation and periglacial processes. In contrast, both Davis and Penck were seeking to emphasize the importance of evolution of landscapes through time and the generality of the Earth's surface processes across different landscapes under different conditions. During

13158-462: The eastern coast of Tyre Island within 6–10 centuries after the construction of the causeway, spurring a radical transformation of the city. Tyre enjoys a reputation of having some of the cleanest beaches and waters of Lebanon. However, a UN HABITAT profile found that "seawater is also polluted due to wastewater discharge especially in the port area". There is still also considerable pollution by solid waste. The Tyre Coast Nature Reserve (TCNR)

13311-587: The emergence of Central Semitic languages, particularly in grammar. Innovations of the Central Semitic languages—all maintained in Arabic—include: There are several features which Classical Arabic, the modern Arabic varieties, as well as the Safaitic and Hismaic inscriptions share which are unattested in any other Central Semitic language variety, including the Dadanitic and Taymanitic languages of

13464-728: The eve of the conquests: Northern and Central (Al-Jallad 2009). The modern dialects emerged from a new contact situation produced following the conquests. Instead of the emergence of a single or multiple koines, the dialects contain several sedimentary layers of borrowed and areal features, which they absorbed at different points in their linguistic histories. According to Veersteegh and Bickerton, colloquial Arabic dialects arose from pidginized Arabic formed from contact between Arabs and conquered peoples. Pidginization and subsequent creolization among Arabs and arabized peoples could explain relative morphological and phonological simplicity of vernacular Arabic compared to Classical and MSA. In around

13617-607: The fact that they participate in the innovations common to all forms of Arabic. The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel , and dated to around 125 CE. This is followed by the Namara inscription , an epitaph of the Lakhmid king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From

13770-430: The field of geomorphology encompasses a very wide range of different approaches and interests. Modern researchers aim to draw out quantitative "laws" that govern Earth surface processes, but equally, recognize the uniqueness of each landscape and environment in which these processes operate. Particularly important realizations in contemporary geomorphology include: According to Karna Lidmar-Bergström , regional geography

13923-590: The force of gravity via creep , slides , flows, topples, and falls. Such mass wasting occurs on both terrestrial and submarine slopes, and has been observed on Earth , Mars , Venus , Titan and Iapetus . Ongoing hillslope processes can change the topology of the hillslope surface, which in turn can change the rates of those processes. Hillslopes that steepen up to certain critical thresholds are capable of shedding extremely large volumes of material very quickly, making hillslope processes an extremely important element of landscapes in tectonically active areas. On

14076-401: The force of gravity , and other factors, such as (in the very recent past) human alteration of the landscape. Many of these factors are strongly mediated by climate . Geologic processes include the uplift of mountain ranges , the growth of volcanoes , isostatic changes in land surface elevation (sometimes in response to surface processes), and the formation of deep sedimentary basins where

14229-494: The form of landscape elements such as rivers and hillslopes by taking systematic, direct, quantitative measurements of aspects of them and investigating the scaling of these measurements. These methods began to allow prediction of the past and future behavior of landscapes from present observations, and were later to develop into the modern trend of a highly quantitative approach to geomorphic problems. Many groundbreaking and widely cited early geomorphology studies appeared in

14382-670: The formation of soils , sediment transport , landscape change, and the interactions between climate, tectonics, erosion, and deposition. In Sweden Filip Hjulström 's doctoral thesis, "The River Fyris" (1935), contained one of the first quantitative studies of geomorphological processes ever published. His students followed in the same vein, making quantitative studies of mass transport ( Anders Rapp ), fluvial transport ( Åke Sundborg ), delta deposition ( Valter Axelsson ), and coastal processes ( John O. Norrman ). This developed into "the Uppsala School of Physical Geography ". Today,

14535-510: The fourth most useful language for business, after English, Mandarin Chinese , and French. Arabic is written with the Arabic alphabet , an abjad script that is written from right to left . Arabic is usually classified as a Central Semitic language . Linguists still differ as to the best classification of Semitic language sub-groups. The Semitic languages changed between Proto-Semitic and

14688-427: The geologic and atmospheric history of those planets but also extends geomorphological study of the Earth. Planetary geomorphologists often use Earth analogues to aid in their study of surfaces of other planets. Other than some notable exceptions in antiquity, geomorphology is a relatively young science, growing along with interest in other aspects of the earth sciences in the mid-19th century. This section provides

14841-597: The inclusion of new words into their published standard dictionaries. They also publish old and historical Arabic manuscripts. In 1997, a bureau of Arabization standardization was added to the Educational, Cultural, and Scientific Organization of the Arab League . These academies and organizations have worked toward the Arabization of the sciences, creating terms in Arabic to describe new concepts, toward

14994-608: The inhabitants are Tyrians . Tyre has a Hot-summer mediterranean climate (classified as Csa under the Köppen climate classification ), characterized by six months of drought from May to October. On average, it has 300 days of sun a year and a yearly temperature of 20.8 °C . The average maximum temperature reaches its highest at 30.8 °C in August and the average minimum temperature its lowest at 10 °C in January. On average,

15147-677: The landscape, they generally increase in size, merging with other rivers. The network of rivers thus formed is a drainage system . These systems take on four general patterns: dendritic, radial, rectangular, and trellis. Dendritic happens to be the most common, occurring when the underlying stratum is stable (without faulting). Drainage systems have four primary components: drainage basin , alluvial valley, delta plain, and receiving basin. Some geomorphic examples of fluvial landforms are alluvial fans , oxbow lakes , and fluvial terraces . Glaciers , while geographically restricted, are effective agents of landscape change. The gradual movement of ice down

15300-474: The landscape. Fluvial geomorphologists focus on rivers , how they transport sediment , migrate across the landscape , cut into bedrock , respond to environmental and tectonic changes, and interact with humans. Soils geomorphologists investigate soil profiles and chemistry to learn about the history of a particular landscape and understand how climate, biota, and rock interact. Other geomorphologists study how hillslopes form and change. Still others investigate

15453-613: The language. Software and books with tapes are an important part of Arabic learning, as many of Arabic learners may live in places where there are no academic or Arabic language school classes available. Radio series of Arabic language classes are also provided from some radio stations. A number of websites on the Internet provide online classes for all levels as a means of distance education; most teach Modern Standard Arabic, but some teach regional varieties from numerous countries. The tradition of Arabic lexicography extended for about

15606-604: The late 6th century AD, a relatively uniform intertribal "poetic koine" distinct from the spoken vernaculars developed based on the Bedouin dialects of Najd , probably in connection with the court of al-Ḥīra . During the first Islamic century, the majority of Arabic poets and Arabic-writing persons spoke Arabic as their mother tongue. Their texts, although mainly preserved in far later manuscripts, contain traces of non-standardized Classical Arabic elements in morphology and syntax. Abu al-Aswad al-Du'ali ( c.  603 –689)

15759-420: The latter is taught in formal education settings. However, there have been studies reporting some degree of comprehension of stories told in the standard variety among preschool-aged children. The relation between Modern Standard Arabic and these dialects is sometimes compared to that of Classical Latin and Vulgar Latin vernaculars (which became Romance languages ) in medieval and early modern Europe. MSA

15912-691: The local climate, for example through orographic precipitation , which in turn modifies the topography by changing the hydrologic regime in which it evolves. Many geomorphologists are particularly interested in the potential for feedbacks between climate and tectonics , mediated by geomorphic processes. In addition to these broad-scale questions, geomorphologists address issues that are more specific or more local. Glacial geomorphologists investigate glacial deposits such as moraines , eskers , and proglacial lakes , as well as glacial erosional features, to build chronologies of both small glaciers and large ice sheets and understand their motions and effects upon

16065-465: The lower lithosphere have also been hypothesised to play important roles in the long term (> million year), large scale (thousands of km) evolution of the Earth's topography (see dynamic topography ). Both can promote surface uplift through isostasy as hotter, less dense, mantle rocks displace cooler, denser, mantle rocks at depth in the Earth. Marine processes are those associated with the action of waves, marine currents and seepage of fluids through

16218-883: The many national or regional varieties which constitute the everyday spoken language. Colloquial Arabic has many regional variants; geographically distant varieties usually differ enough to be mutually unintelligible , and some linguists consider them distinct languages. However, research indicates a high degree of mutual intelligibility between closely related Arabic variants for native speakers listening to words, sentences, and texts; and between more distantly related dialects in interactional situations. The varieties are typically unwritten. They are often used in informal spoken media, such as soap operas and talk shows , as well as occasionally in certain forms of written media such as poetry and printed advertising. Hassaniya Arabic , Maltese , and Cypriot Arabic are only varieties of modern Arabic to have acquired official recognition. Hassaniya

16371-470: The mean annual precipitation reaches up to 645 mm. The temperature of the sea water reaches a minimum of 17 °C in February and a maximum of 32 °C in August. At a depth of 70 m it is constantly at 17–18 °C. Meanwhile, rising sea levels due to global warming threaten coastal erosion to Tyre's peninsula and bay areas. The ancient city of Tyre is located along the coast of Phoenicia in modern Lebanon. The site has been occupied since

16524-516: The mid-20th century considered both un-innovative and dubious. Early climatic geomorphology developed primarily in continental Europe while in the English-speaking world the tendency was not explicit until L.C. Peltier's 1950 publication on a periglacial cycle of erosion. Climatic geomorphology was criticized in a 1969 review article by process geomorphologist D.R. Stoddart . The criticism by Stoddart proved "devastating" sparking

16677-588: The name of the city means 'rock' after the rocky formation on which the town was originally built. The predominant form in Classical Greek was Týros ( Τύρος ), which was first seen in the works of Herodotus but may have been adopted considerably earlier. It gave rise to Latin Tyrus , which entered English during the Middle English period as Tyre . The demonym for Tyre is Tyrian , and

16830-782: The need for a lexical injection in Arabic, to suit concepts of the industrial and post-industrial age (such as sayyārah سَيَّارَة 'automobile' or bākhirah باخِرة 'steamship'). In response, a number of Arabic academies modeled after the Académie française were established with the aim of developing standardized additions to the Arabic lexicon to suit these transformations, first in Damascus (1919), then in Cairo (1932), Baghdad (1948), Rabat (1960), Amman (1977), Khartum  [ ar ] (1993), and Tunis (1993). They review language development, monitor new words and approve

16983-401: The northeastern outskirts of Tyre. The city of Tyre appears in many biblical traditions: A multi-ring structured region on Europa , the smallest of the four Galilean moons orbiting Jupiter , is named after Tyre, the legendary birthplace of princess Europa. Originally called "Tyre Macula ", it is some 140 kilometers in diameter (about the size of the island of Hawaii ) and thought to be

17136-665: The northern harbour area of Tyre. In 2003, Randa Berri, president of the National Association for the Preservation of South Lebanon's Archaeology and Heritage and wife of Nabih Berri , veteran leader of the Amal Movement and longtime Speaker of the Parliament of Lebanon, patronized a plan to renovate Khan Sour / Khan Al Askaar, the former Ma'ani palace, and convert it into a museum. As of 2019, nothing

17289-424: The one whose sound is heard but whose person remains unseen. Now the term al-hatif is used for a telephone. Therefore, the process of tawleed can express the needs of modern civilization in a manner that would appear to be originally Arabic. In the case of Arabic, educated Arabs of any nationality can be assumed to speak both their school-taught Standard Arabic as well as their native dialects, which depending on

17442-550: The original island not covered by the modern city of Tyre is mostly of an archaeological site showcasing remains of the city from ancient times. Four municipalities contribute to Tyre city's 16.7 km built-up area, though none are included in their entirety: Sour municipality contains the heart of the city, excluding the Natural and Coastal Reserve; Burj El Shimali to the East without unpopulated agricultural lands; Abbasiyet Sour to

17595-549: The overhaul of Arabic grammar first proposed by Al-Jahiz 200 years prior. The Maghrebi lexicographer Ibn Manzur compiled Lisān al-ʿArab ( لسان العرب , "Tongue of Arabs"), a major reference dictionary of Arabic, in 1290. Charles Ferguson 's koine theory claims that the modern Arabic dialects collectively descend from a single military koine that sprang up during the Islamic conquests; this view has been challenged in recent times. Ahmad al-Jallad proposes that there were at least two considerably distinct types of Arabic on

17748-857: The physics of landscapes. Geomorphologists may rely on geochronology , using dating methods to measure the rate of changes to the surface. Terrain measurement techniques are vital to quantitatively describe the form of the Earth's surface, and include differential GPS , remotely sensed digital terrain models and laser scanning , to quantify, study, and to generate illustrations and maps. Practical applications of geomorphology include hazard assessment (such as landslide prediction and mitigation ), river control and stream restoration , and coastal protection. Planetary geomorphology studies landforms on other terrestrial planets such as Mars. Indications of effects of wind , fluvial , glacial , mass wasting , meteor impact , tectonics and volcanic processes are studied. This effort not only helps better understand

17901-484: The presence of archaeological remains at proposed construction sites. The sites have not been investigated. Despite the relocation of a proposed traffic interchange, the lack of precise site boundaries confuses the issue of site preservation. A 2018 study of Mediterranean world heritage sites found that Tyre's City site has "the highest risk of coastal erosion under current climatic conditions, in addition to 'moderate' risk from extreme sea levels." Further coastal inspection

18054-436: The priests there, the city was founded 2300 years earlier (around 2750 BCE), as a walled place upon the mainland, now known as Paleotyre (Old Tyre). The Phoenician Tyrians' international trade network was based on its two harbours which are mentioned by ancient writers (Arrian, Anabasis, 2, 24; Strabo, Geography, 16,2,23). The northern harbour opened toward the Phoenician city of Sidon and has been therefore referred to as

18207-410: The region may be mutually unintelligible. Some of these dialects can be considered to constitute separate languages which may have "sub-dialects" of their own. When educated Arabs of different dialects engage in conversation (for example, a Moroccan speaking with a Lebanese), many speakers code-switch back and forth between the dialectal and standard varieties of the language, sometimes even within

18360-423: The relationships between ecology and geomorphology. Because geomorphology is defined to comprise everything related to the surface of the Earth and its modification, it is a broad field with many facets. Geomorphologists use a wide range of techniques in their work. These may include fieldwork and field data collection, the interpretation of remotely sensed data, geochemical analyses, and the numerical modelling of

18513-616: The results, she suggested that the Al Mobarakee Tower may actually date back to Hellenistic times. All those works stopped though soon after the 1975 beginning of the Civil War and many records were lost. In 1984, the United Nations Educational, Scientific and Cultural Organisation (UNESCO) declared Tyre a World Heritage Site in an attempt to halt the damage being done to the archaeological sites by

18666-487: The role of biology in mediating surface processes can be definitively excluded are extremely rare, but may hold important information for understanding the geomorphology of other planets, such as Mars . Rivers and streams are not only conduits of water, but also of sediment . The water, as it flows over the channel bed, is able to mobilize sediment and transport it downstream, either as bed load , suspended load or dissolved load . The rate of sediment transport depends on

18819-532: The rubble. Its unusual design suggests that this was the site of the Cathedral of Paulinus which had been inaugurated in 315 CE. In 1997, the first Phoenician cremation cemetery was uncovered in the al-Bass site , near the Roman necropolis. Meanwhile, Honor Frost mentored local Lebanese archaeologists to conduct further underwater investigations, which in 2001 confirmed the existence of a human-made structure within

18972-458: The same sentence. The issue of whether Arabic is one language or many languages is politically charged, in the same way it is for the varieties of Chinese , Hindi and Urdu , Serbian and Croatian , Scots and English, etc. In contrast to speakers of Hindi and Urdu who claim they cannot understand each other even when they can, speakers of the varieties of Arabic will claim they can all understand each other even when they cannot. While there

19125-760: The science of historical geology . While acknowledging its shortcomings, modern geomorphologists Andrew Goudie and Karna Lidmar-Bergström have praised it for its elegance and pedagogical value respectively. Geomorphically relevant processes generally fall into (1) the production of regolith by weathering and erosion , (2) the transport of that material, and (3) its eventual deposition . Primary surface processes responsible for most topographic features include wind , waves , chemical dissolution , mass wasting , groundwater movement, surface water flow, glacial action , tectonism , and volcanism . Other more exotic geomorphic processes might include periglacial (freeze-thaw) processes, salt-mediated action, changes to

19278-409: The science of geomorphology. The model or theory has never been proved wrong, but neither has it been proven. The inherent difficulties of the model have instead made geomorphological research to advance along other lines. In contrast to its disputed status in geomorphology, the cycle of erosion model is a common approach used to establish denudation chronologies , and is thus an important concept in

19431-480: The sea, eventually those seas would fill while the land lowered. He claimed that this would mean that land and water would eventually swap places, whereupon the process would begin again in an endless cycle. The Encyclopedia of the Brethren of Purity published in Arabic at Basra during the 10th century also discussed the cyclical changing positions of land and sea with rocks breaking down and being washed into

19584-525: The sea, their sediment eventually rising to form new continents. The medieval Persian Muslim scholar Abū Rayhān al-Bīrūnī (973–1048), after observing rock formations at the mouths of rivers, hypothesized that the Indian Ocean once covered all of India . In his De Natura Fossilium of 1546, German metallurgist and mineralogist Georgius Agricola (1494–1555) wrote about erosion and natural weathering . Another early theory of geomorphology

19737-755: The seabed caused by marine currents, seepage of fluids through the seafloor or extraterrestrial impact. Aeolian processes pertain to the activity of the winds and more specifically, to the winds' ability to shape the surface of the Earth . Winds may erode, transport, and deposit materials, and are effective agents in regions with sparse vegetation and a large supply of fine, unconsolidated sediments . Although water and mass flow tend to mobilize more material than wind in most environments, aeolian processes are important in arid environments such as deserts . The interaction of living organisms with landforms, or biogeomorphologic processes , can be of many different forms, and

19890-501: The seafloor within 150 m of the former island. Antoine Poidebard, who was the first to have them explored by divers in 1939, saw in these structures former breakwaters enclosing a harbour with two entrances. The geographic area enclosed within these structures is therefore often referred to as the “Southern Harbour”. These structures have also been interpreted as a polder-like area protecting an urban district (El-Amouri et al., 2005; Frost, 1971; Renan, 1864–1874). A Phoenician-style breakwater

20043-459: The seafloor. Mass wasting and submarine landsliding are also important processes for some aspects of marine geomorphology. Because ocean basins are the ultimate sinks for a large fraction of terrestrial sediments, depositional processes and their related forms (e.g., sediment fans, deltas ) are particularly important as elements of marine geomorphology. There is a considerable overlap between geomorphology and other fields. Deposition of material

20196-454: The singer Fairuz and introduced her to the Rahbani brothers . Roumi composed music for and with them in close collaborations. Arabic language Arabic (endonym: اَلْعَرَبِيَّةُ , romanized :  al-ʿarabiyyah , pronounced [al ʕaraˈbijːa] , or عَرَبِيّ , ʿarabīy , pronounced [ˈʕarabiː] or [ʕaraˈbij] ) is

20349-468: The site where an asteroid or comet impacted Europa's ice crust. The asteroid 209 Dido is named after the legendary Tyrian-Carthaginian princess. It is a very large main-belt asteroid , classified as a C-type asteroid which is probably composed of carbonaceous materials. 209 Dido was discovered in 1879 by C. H. F. Peters . The first cinema in Tyre opened in the late 1930s when a café owner established makeshift film screenings. Hamid Istanbouli –

20502-458: The sole example of Medieval linguist Abu Hayyan al-Gharnati – who, while a scholar of the Arabic language, was not ethnically Arab – Medieval scholars of the Arabic language made no efforts at studying comparative linguistics, considering all other languages inferior. In modern times, the educated upper classes in the Arab world have taken a nearly opposite view. Yasir Suleiman wrote in 2011 that "studying and knowing English or French in most of

20655-563: The standardization of these new terms throughout the Arabic-speaking world, and toward the development of Arabic as a world language . This gave rise to what Western scholars call Modern Standard Arabic. From the 1950s, Arabization became a postcolonial nationalist policy in countries such as Tunisia, Algeria, Morocco, and Sudan. Arabic usually refers to Standard Arabic, which Western linguists divide into Classical Arabic and Modern Standard Arabic. It could also refer to any of

20808-407: The surface of the Earth drops and is filled with material eroded from other parts of the landscape. The Earth's surface and its topography therefore are an intersection of climatic , hydrologic , and biologic action with geologic processes, or alternatively stated, the intersection of the Earth's lithosphere with its hydrosphere , atmosphere , and biosphere . The broad-scale topographies of

20961-596: The surface, depending on whether the new material is denser or less dense than the rock it displaces. Tectonic effects on geomorphology can range from scales of millions of years to minutes or less. The effects of tectonics on landscape are heavily dependent on the nature of the underlying bedrock fabric that more or less controls what kind of local morphology tectonics can shape. Earthquakes can, in terms of minutes, submerge large areas of land forming new wetlands. Isostatic rebound can account for significant changes over hundreds to thousands of years, and allows erosion of

21114-501: The towns where the inscriptions were discovered (Dadanitic, Taymanitic, Hismaic, Safaitic). However, most arguments for a single ANA language or language family were based on the shape of the definite article, a prefixed h-. It has been argued that the h- is an archaism and not a shared innovation, and thus unsuitable for language classification, rendering the hypothesis of an ANA language family untenable. Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to

21267-451: The world have classes that teach Arabic as part of their foreign languages , Middle Eastern studies , and religious studies courses. Arabic language schools exist to assist students to learn Arabic outside the academic world. There are many Arabic language schools in the Arab world and other Muslim countries. Because the Quran is written in Arabic and all Islamic terms are in Arabic, millions of Muslims (both Arab and non-Arab) study

21420-402: The “Sidonian Harbour” by 19th and 20th century scholars, but it was referred to as the "Port of Astronoe" during Late Antiquity. The southern harbour opened toward Egypt and was referred to as the “Egyptian Harbour”. The location of the two harbours has been the subject of speculations since the 17th Century. The submarine excavation of a large, 4-6th Century BCE breakwater north of the city, and

21573-434: Was German, and during his lifetime his ideas were at times rejected vigorously by the English-speaking geomorphology community. His early death, Davis' dislike for his work, and his at-times-confusing writing style likely all contributed to this rejection. Both Davis and Penck were trying to place the study of the evolution of the Earth's surface on a more generalized, globally relevant footing than it had been previously. In

21726-444: Was an elaboration of the uniformitarianism theory that had first been proposed by James Hutton (1726–1797). With regard to valley forms, for example, uniformitarianism posited a sequence in which a river runs through a flat terrain, gradually carving an increasingly deep valley, until the side valleys eventually erode, flattening the terrain again, though at a lower elevation. It was thought that tectonic uplift could then start

21879-416: Was better described as an alternation between ongoing processes of uplift and denudation, as opposed to Davis's model of a single uplift followed by decay. He also emphasised that in many landscapes slope evolution occurs by backwearing of rocks, not by Davisian-style surface lowering, and his science tended to emphasise surface process over understanding in detail the surface history of a given locality. Penck

22032-544: Was conducted in 2019, leading to a new hypothesis about the local relative sea level rise and to discovery of yet unreported submerged coastal structures. Like many of the cities in the Levant and in Lebanon , the architecture since the Lebanese Civil War in the 1970s has been of poor quality, which tend to threaten the cultural heritage in the built environment before the war. Meanwhile, historical buildings from

22185-602: Was decreed in 1998 by the Ministry of Public Works . It is 3.5 km (2.2 mi) long and covers over 380 hectares (940 acres). The TCNR is within the best preserved stretch of sandy coastline in southern Lebanon and divided into two section zones: a 1.8 km sand lined beach, 1.8 km long and 500 meters wide-ranging from the Tyre Rest House in the north to the Rashidieh Refugee Camp in the South, and

22338-507: Was devised by Song dynasty Chinese scientist and statesman Shen Kuo (1031–1095). This was based on his observation of marine fossil shells in a geological stratum of a mountain hundreds of miles from the Pacific Ocean . Noticing bivalve shells running in a horizontal span along the cut section of a cliffside, he theorized that the cliff was once the pre-historic location of a seashore that had shifted hundreds of miles over

22491-502: Was done by a French team under the leadership of Denyse Le Lasseur in 1921. It was followed by another mission between 1934 and 1936 that included aerial surveys and diving expeditions. It was led by the Jesuit missionary Antoine Poidebard , a pioneer of aerial archaeology . Large-scale excavations started in 1946 under the leadership of Emir Maurice Chéhab (1904–1994), "the father of modern Lebanese archaeology" who for decades headed

22644-456: Was done in that regard and the ruins have kept on crumbling. The hostilities of the 2006 Lebanon War put the ancient structures of Tyre at risk. This prompted UNESCO 's Director-General to launch a "Heritage Alert" for the site. Following the cessation of hostilities in September 2006, a visit by conservation experts to Lebanon observed no direct damage to the ancient city of Tyre. However,

22797-537: Was followed in the 1870s by Johannes Nepemuk Sepp. His most notable work was excavating at the cathedral in an attempt to find the bones of Frederick Barbarossa . More work was undertaken in 1903 by the Greek archaeologist Theodore Makridi , curator of the Imperial Museum at Constantinople . Important findings like fragments of marble sarcophagi were sent to the Ottoman capital. An archaeological survey of Tyre

22950-402: Was foreshadowed by the work of Wladimir Köppen , Vasily Dokuchaev and Andreas Schimper . William Morris Davis , the leading geomorphologist of his time, recognized the role of climate by complementing his "normal" temperate climate cycle of erosion with arid and glacial ones. Nevertheless, interest in climatic geomorphology was also a reaction against Davisian geomorphology that was by

23103-439: Was inherited as " S‘r " is the Phoenician word for "rock". It had two ports, the "Sidonian port" to the north, still partly existing today, and the "Egyptian port" to the south which has perhaps been discovered very recently. Throughout history from prehistoric times onwards, all settlements in the Tyre area profited from the abundance of fresh water supplies, especially from the nearby springs of Rashidieh and Ras Al Ain in

23256-501: Was one of the earliest Phoenician metropolises and the legendary birthplace of Europa , her brothers Cadmus and Phoenix , as well as Carthage 's founder Dido (Elissa). The city has many ancient sites, including the Tyre Hippodrome , and was added as a whole to the list of UNESCO World Heritage Sites in 1984. The historian Ernest Renan noted that "One can call Tyre a city of ruins, built out of ruins". Today, Tyre

23409-538: Was recently found within this area, but excavation is needed to confirm its age ascription. Harbour sediments found behind the structure suggest that the breakwater was part of the Egyptian harbour. Harbour sediments found near Hiram's Tower, further north, mark an early location of the Sidonian Harbour. The development of Tyre was profoundly affected by the construction of a causeway built by Alexander
