61-520: Development of water resources in Turkey began with the establishment of the "General Directorate of Public Works" ( Ottoman Turkish : Umur-u Nafia Müdüriyet-i Umumiyesi ) by the Ottoman Government in 1914. The institution started to undertake continuous and systematical studies on irrigation , reclamation , flood control , navigation, water storage and distribution. in 1925, soon after

122-425: A [d] when followed by a vowel sound. This is reflected in conventions of Ottoman orthography as well. In Turkish, there is a verb representing to be , but it is a defective verb. It doesn't have an infinitive or several other tenses. It is usually a suffix. Negative verb to be is created with the use of the word دگل değil , followed by the appropriate conjugation of the to be verb; or optionally used as

183-606: A decision backed by President Recep Tayyip Erdoğan , who said the language should be taught in schools so younger generations do not lose touch with their cultural heritage. Most Ottoman Turkish was written in the Ottoman Turkish alphabet ( Ottoman Turkish : الفبا , romanized :  elifbâ ), a variant of the Perso-Arabic script . The Armenian , Greek and Rashi script of Hebrew were sometimes used by Armenians, Greeks and Jews. (See Karamanli Turkish ,

244-508: A dialect of Ottoman written in the Greek script; Armeno-Turkish alphabet ) The actual grammar of Ottoman Turkish is not different from the grammar of modern Turkish .The focus of this section is on the Ottoman orthography; the conventions surrounding how the orthography interacted and dealt with grammatical morphemes related to conjugations, cases, pronouns, etc. Table below lists nouns with

305-676: A document but would use the native Turkish word bal ( بال ) when buying it. The transliteration system of the İslâm Ansiklopedisi has become a de facto standard in Oriental studies for the transliteration of Ottoman Turkish texts. In transcription , the New Redhouse, Karl Steuerwald, and Ferit Devellioğlu dictionaries have become standard. Another transliteration system is the Deutsche Morgenländische Gesellschaft (DMG), which provides

366-411: A single root verb, with the addition of a variety of morphemes and suffixes, multiple new and different verbs meanings can be expressed in single but larger words. Below table is a sample from the verb تپمك tepmek meaning 'to kick', whose root (which is also 2nd person imperative) is تپ tep . Each of the produced new verbs below can be made into an infinitive with the addition of ـمك -mek at

427-427: A standalone for 3rd person. Generally, the verbs 'to exist' and 'to have' are expressed using what's called an existential copula , the word وار var . The verb 'to have' is expressed in the same way, except that the object noun will take a possessive pronoun, producing sentences that will literally mean "there exists house of mine". The verbs 'to exist' and 'to have' conjugated for other tenses, are expressed in

488-490: A third. Syria and Iraq claim to be suffering severe water shortages due to the GAP development. Both countries allege that Turkey is intentionally withholding supplies from its downstream neighbors, turning water into a weapon. Turkey denies these claims, and insists it has always supplied its southern neighbors with the promised minimum of 500 m /s (18,000 cu ft/s). It argues that Iraq and Syria in fact benefit from

549-458: A total installed power capacity of 2,400 MW and generates 8,900 GW·h electricity annually. The total cost of the dam project was about US$ 1,250,000,000. The dam was depicted on the reverse of the Turkish one-million- lira banknotes of 1995–2005 and of the 1 new lira banknote of 2005–2009. The initial development project for the southeastern region of Turkey was presented in 1970. As

610-472: A total of around 2.5 km domestic water complying with drinking water standards. This figure will reach 5.3 km with completion of the projects which are under construction, or at the final design and planning stages. Water supply projects developed by State Hydraulic Works meet one third of the requirements for domestic and industrial water consumption. Climate change in Turkey is putting pressure on water resources. The protection of nature and wildlife

671-542: A total weight of 26.600 tons were supplied and installed by the German NOELL company (today DSD NOELL ). The power plant's first two power units came on line in 1992 and it became fully operational in December 1993. The HEPP can generate 8,900 GWh of electricity annually. Its capacity makes up around one third of the total capacity of the GAP project. During the periods of low demand for electricity, only one of

732-658: A transliteration system for any Turkic language written in Arabic script. There are few differences between the İA and the DMG systems. Atat%C3%BCrk Dam The Atatürk Dam ( Turkish : Atatürk Barajı ), originally the Karababa Dam , is the third largest dam in the world and it is a zoned rock-fill dam with a central core on the Euphrates River on the border of Adıyaman Province and Şanlıurfa Province in

793-435: A variety of phonological features that come into play when taking case suffixes. The table includes a typical singular and plural noun, containing back and front vowels, words that end with the letter ه ـه ([a] or [e]), both back and front vowels, word that ends in a ت ([t]) sound, and word that ends in either ق or ك ([k]). These words are to serve as references, to observe orthographic conventions: Table below shows

854-572: Is 542 m (1,778 ft), and the minimum operation level is 526 m (1,726 ft) amsl. Some 10 towns and 156 villages of three provinces are located around the Lake Atatürk Dam. The lake provides a fisheries and recreation site. For transportation purposes, several ferries have been operated in the reservoir. The reservoir lake is called "sea" by local people. About 90% of Euphrates' total annual flow originates in Turkey , while

915-677: Is building and operating protective structures against floods. It takes the necessary precautions and warns the relevant organizations in the event of flood emergencies. State Hydraulic Works conducts afforestation work and establishes recreation areas and facilities aiming at prevention of erosion, decreasing the sediment amount deposited in dams through rivers, restoring the environment of dam basins and their catchments. Tree planted areas also serve as picnic areas and public promenades. State Hydraulic Works needs to obtain land properties (real estates) for its development projects of water and land resources. Up to now, around 5,200 km of private land

976-409: Is compound verbs. This consists of adding a Persian or Arabic active or passive participle to a neuter verb, to do ( ایتمك etmek ) or to become ( اولمق olmaq ). For example, note the following two verbs: Below table shows some sample conjugations of these two verbs. The conjugation of the verb "etmek" isn't straightforward, because the root of the verb ends in a [t]. This sound transforms into

1037-622: Is currently being irrigated. As of 2005, an area of 28,000 km is equipped with facilities of State Hydraulic Works's irrigation projects, making 10% of the total agricultural area and 57% of the irrigated area in Turkey. The Southeastern Anatolia Project ( Turkish : Güneydoğu Anadolu Projesi or GAP), a very important integrated project for the economic and social development of the Southeastern Anatolia Region , includes active farming with extensive irrigation systems and electricity generation. The project area covers

1098-451: Is estimated that the central portion of the dam crest has settled by around 7 m (23 ft) since the end of the construction. Settlement of the dam crest up to 4.3 m (14 ft) has been measured since the start of the detailed geodetic monitoring in 1992. The maximum horizontal (radial) deformation measured is about 2.9 m (9.5 ft). The permeation grouting work was carried out by subcontractor Solétanche Bachy and

1159-441: Is of great importance for State Hydraulic Works. It conducts activities on development of sustainable water resources, both independently and in collaboration with other related governmental and non-governmental organizations. State Hydraulic Works also provides financial and technical support to protect archaeological and historical sites for the next generations. One of the basic duties and responsibilities of State Hydraulic Works

1220-531: Is one of the world's largest dams . The Atatürk Dam, one of the five operational dams on the Euphrates as of 2008, was preceded by Keban and Karakaya dams upstream and followed by Birecik and the Karkamış dams downstream. Two more dams on the river have been under construction. The dam embankment is 169 m high (554 ft) and 1,820 m long (5,970 ft). The hydroelectric power plant (HEPP) has

1281-450: Is partly responsible for water supply and sanitation in Turkey and is responsible by law for the supply of domestic and industrial water to settlements having population of more than 100,000. As of the 2000 census, there are 55 cities and towns in Turkey with populations over 100,000. State Hydraulic Works supply water to 26 million people in 45 cities at different regions. As of the beginning of 2005, State Hydraulic Works supplied annually

1342-469: Is the basis of the modern standard. The Tanzimât era (1839–1876) saw the application of the term "Ottoman" when referring to the language ( لسان عثمانی lisân-ı Osmânî or عثمانلیجه Osmanlıca ); Modern Turkish uses the same terms when referring to the language of that era ( Osmanlıca and Osmanlı Türkçesi ). More generically, the Turkish language was called تركچه Türkçe or تركی Türkî "Turkish". Historically, Ottoman Turkish

1403-497: The Southeastern Anatolia Region of Turkey . Built both to generate electricity and to irrigate the plains in the region, it was renamed in honour of Mustafa Kemal Atatürk (1881–1938), the founder of the Turkish Republic . The construction began in 1983 and was completed in 1990. The dam and the hydroelectric power plant , which went into service after the upfilling of the reservoir was completed in 1992, are operated by

1464-631: The State Hydraulic Works (DSİ) . The reservoir created behind the dam, called Atatürk Reservoir ( Turkish : Atatürk Baraj Gölü ), is the third largest in Turkey. The dam is situated 23 km (14 mi) northwest of Bozova , Şanlıurfa Province, on state road D-875 from Bozova to Adıyaman . Centerpiece of the 22 dams on the Euphrates and the Tigris , which comprise the integrated, multi-sector, Southeastern Anatolia Project ( Turkish : Güney Doğu Anadolu Projesi , known as GAP), it

1525-592: The list of replaced loanwords in Turkish for more examples of Ottoman Turkish words and their modern Turkish counterparts. Two examples of Arabic and two of Persian loanwords are found below. Historically speaking, Ottoman Turkish is the predecessor of modern Turkish. However, the standard Turkish of today is essentially Türkiye Türkçesi (Turkish of Turkey) as written in the Latin alphabet and with an abundance of neologisms added, which means there are now far fewer loan words from other languages, and Ottoman Turkish

1586-402: The 1960s, Ottoman Turkish was at least partially intelligible with the Turkish of that day. One major difference between Ottoman Turkish and modern Turkish is the latter's abandonment of compound word formation according to Arabic and Persian grammar rules. The usage of such phrases still exists in modern Turkish but only to a very limited extent and usually in specialist contexts ; for example,

1647-545: The Euphrates Basin and 6 of which are in the Tigris Basin. Within the scope of these 13 projects, 27,000 GWh hydroelectric energy will be produced annually with 7.5 GW installed capacity and 18,200 km of land will be irrigated with the construction of 22 dams and 19 HEPPs. The Atatürk Dam , the largest in Turkey and among the world's largest dams , is the centerpiece of the project. State Hydraulic Works

1708-466: The Euphrates entirely for a month to begin filling up the reservoir. Turkey had notified Syria and Iraq by November 1989 of her decision to fill the reservoir over a period of one month explaining the technical reasons and providing a detailed program for making up for the losses. The downstream neighbors protested vehemently. At this point, the Atatürk Dam has cut the flow from the Euphrates by about

1769-571: The Euphrates-Tigris river system is the protocol annexed to the 1946 Treaty of Friendship and Good Neighborly Relations between Iraq and Turkey. The protocol provided the control and management of the Euphrates and the Tigris depending to a large extent on the regulations of flow in Turkish source areas. Turkey agreed to begin monitoring the two border-crossing rivers and to share related data with Iraq. In 1980, Turkey and Iraq further specified

1830-543: The Persian genitive construction takdîr-i ilâhî (which reads literally as "the preordaining of the divine" and translates as "divine dispensation" or "destiny") is used, as opposed to the normative modern Turkish construction, ilâhî takdîr (literally, "divine preordaining"). In 2014, Turkey's Education Council decided that Ottoman Turkish should be taught in Islamic high schools and as an elective in other schools,

1891-538: The Persian character of its Arabic borrowings with other Turkic languages that had even less interaction with Arabic, such as Tatar , Bashkir , and Uyghur . From the early ages of the Ottoman Empire, borrowings from Arabic and Persian were so abundant that original Turkish words were hard to find. In Ottoman, one may find whole passages in Arabic and Persian incorporated into the text. It was however not only extensive loaning of words, but along with them much of

1952-647: The Tigris are very irregular rivers, used to cause great problems each year with droughts in summer and flooding in winter. The water of the Euphrates River is regulated by means of large reservoirs of the Keban and Atatürk Dams. However, the waters released from the HEPPs of those dams also need to be regulated. The Birecik and the Karkamış Dams downstream the Atatürk Dam are constructed for the purpose of harnessing

2013-442: The additional - ـنـ [n] is a vowel, the final vowel ی is kept; otherwise it is removed (note the respective examples for kitaplarını versus kitaplarından ). Examples below : Below table shows the positive conjugation for two sample verbs آچمق açmak (to open) and سولمك sevilmek (to be loved). The first verb is the active verb, and the other has been modified to form a passive verb. The first contains back vowels,

2074-466: The building of the dam. The construction of the cofferdam began in 1985 and was completed in 1987. The fill work for the main dam lasted from 1987 to 1990. The Atatürk Dam, listed in international construction publications as the world's largest construction site, was completed in a world record time of around 50 months. The rock-fill dam undergoes deformations that are regularly and systematically monitored since 1990 with different types of sensors. It

2135-448: The country's cotton production, the region developed to the leader in Turkey. The Atatürk Reservoir , extending over an area of 817 km (315 sq mi) with a water volume of 48.7 km (63,400 million cu yd), ranks third in size in Turkey after Lake Van and Lake Tuz . The reservoir water level touched 535 m (1,755 ft) amsl in 1994. Since then, it varies between 526 and 537 m amsl. The full reservoir level

2196-427: The country's total electric power capacity) and generated in 2003 electricity of 35,329 GWh (25.1% of the total). State Hydraulic Works has currently 24 HEPPs throughout the country under construction with a total installed capacity of 2,722 MW and annual generation of 8,920 GWh. Turkey has a total of 280,000 square kilometres of agricultural area, of which 85,000 km is economically irrigable and 49,000 km

2257-467: The eight units of the HEPP is in operation while in times of high demand, all the eight units are in operation. Hence, depending upon the energy demand and the state of the interconnected system, the amount of water to be released from the HEPP might vary between 200 and 2,000 m /s in one day. Originating in the mountains of eastern Anatolia and flowing southwards to Syria and Iraq , the Euphrates and

2318-417: The end. Ottoman Turkish was highly influenced by Arabic and Persian. Arabic and Persian words in the language accounted for up to 88% of its vocabulary. As in most other Turkic and foreign languages of Islamic communities, the Arabic borrowings were borrowed through Persian, not through direct exposure of Ottoman Turkish to Arabic, a fact that is evidenced by the typically Persian phonological mutation of

2379-541: The foundation of the Turkish Republic, regional offices were opened in Adana , Ankara , Bursa , Edirne and İzmir under the "Waters Directorate". Due to insufficient financial resources and field observations data available, water projects could not be expedited as planned. Severe drought, occurred in 1929, led to the establishment of the more comprehensive institution of "Waters General Directorate". In 1939, it

2440-422: The grammatical systems of Persian and Arabic. In a social and pragmatic sense, there were (at least) three variants of Ottoman Turkish: A person would use each of the varieties above for different purposes, with the fasih variant being the most heavily suffused with Arabic and Persian words and kaba the least. For example, a scribe would use the Arabic asel ( عسل ) to refer to honey when writing

2501-465: The lower parts of the Euphrates and Tigris rivers in the 9 provinces of the region ( Gaziantep , Adıyaman , Kilis , Şanlıurfa , Diyarbakır , Mardin , Siirt , Batman , and Şırnak ), where a total of 6.5 million people live as of the 2000 census. The project is one of the biggest investments of the last century undertaken by State Hydraulic Works and contains 13 sub-projects, 7 of which are in

2562-587: The minister of environment and forestry. The State Hydraulic Works is organized in three levels: The management, the department offices and the regional offices. While the first two levels are located in Ankara , the 25 regional offices are dispersed throughout Turkey. Major functions of the regional offices are primarily collection of data in the field of mapping, conducting hydrometric measurements, surveying agricultural economy, land classification, drainage, groundwater and geology, and secondly to evaluate them for

2623-403: The nature of the earlier protocol by forming a joint committee on technical issues, which Syria joined later in 1982 as well. Turkey unilaterally guaranteed to allow 15.75 km /year (500 m /s) of water across the border to Syria without any formal agreement on the sharing of the Euphrates water. Mid-January 1990, when the first phase of the dam was completed, Turkey held back the flow of

2684-516: The objectives for regional development have changed significantly and the ambitions have grown in the 1970s, the original plan underwent major modifications. The most important change in the project was abandoning the Middle Karababa Dam design, and adopting the design of the Atatürk Dam to increase the storage and power generation capacities of the dam. Dolsar Engineering and ATA Construction, two prominent Turkish companies, signed for

2745-431: The planning, construction and operation of water structures. Since its establishment in 1954, State Hydraulic Works has made investments in the sector of energy for US$ 30.0 billion, agriculture for US$ 39.0 billion and services for US$ 12.0 billion, totaling up to US$ 81.0 billion. Of the 135 hydroelectric power plants in Turkey , State Hydraulic Works operates 53, which have a total installed capacity of 10,215 MW (29% of

2806-415: The reform was the Turkish nationalist Ziya Gökalp . It also saw the replacement of the Perso-Arabic script with the extended Latin alphabet . The changes were meant to encourage the growth of a new variety of written Turkish that more closely reflected the spoken vernacular and to foster a new variety of spoken Turkish that reinforced Turkey's new national identity as being a post-Ottoman state . See

2867-537: The regulated water by the dams as they protect all three riparian countries from seasonal droughts and floods. Two damaging earthquakes of M w 5.5 and M w 5.1 occurred in the town of Samsat near the Atatürk Reservoir in 2017 and 2018, respectively. The spatio-temporal evolution of seismicity and its source properties in relation to the temporal water-level variations and the stresses resulting from surface loading and pore-pressure diffusion shows

2928-464: The rehabilitation work for the post-tensioning of the dam crest with ground anchors by Vorspann System Losinger International (VSL). The HEPP of the Atatürk Dam is the biggest of a series of 19 power plants of the GAP project. It consists of eight Francis turbine and generator groups of 300 MW each, supplied by Sulzer Escher Wyss and ABB Asea Brown Boveri respectively. The up to 7.25-metre-diameter (23.8 ft) steel pressure pipes (penstocks) with

2989-504: The remaining part is added in Syria , but nothing is contributed further downstream in Iraq. In general, the stream varies greatly in its flow from season to season and year to year. As an example, the annual flow at the border with Syria ranged from 15.3 km (3.7 cu mi) in 1961 to 42.7 km (10.2 cu mi) in 1963. One of the most important legal texts on the waters of

3050-496: The same way, with a possessive pronoun if needed, and copula وار var , followed by the 3rd person singular form of the verb 'to do: ایتمك etmek attached as a suffix (or separate as a stanadalone verb); as conjugated in the above section. The verbs 'not to exist' and 'not to have' are created in the exact same manner and conjugation, except that the copula یوق yok is used. Turkish being an agglutinative language as opposed to an analytical one (generally), means that from

3111-609: The second front vowels; both containing non-rounded vowels (which also impacts pronounciation and modern Latin orthograhpy). Below table shows the conjugation of a negative verb, and a positive complex verb expressing ability. In Turkish, complex verbs can be constructed by adding a variety of suffixes to the base root of a verb. The two verbs are یازممق yazmamaq (not to write) and سوه‌بلمك sevebilmek (to be able to love). Another common category of verbs in Turkish (more common in Ottoman Turkish than in modern Turkish),

3172-410: The suffixes for creating possessed nouns. Each of these possessed nouns, in turn, take case suffixes as shown above. For third person (singular and plural) possessed nouns, that end in a vowel, when it comes to taking case suffixes, a letter - ـنـ [n] comes after the possessive suffix. For singular endings, the final vowel ی is removed in all instances. For plural endings, if the letter succeeding

3233-413: The tunnels is about 328 m /s (11,600 cu ft/s), which makes one-third of the total flow of the Euphrates. The tunnels are the largest in the world, in terms of length and flow rate, built for irrigation purposes. The first tunnel was completed in 1995 and the other in 1996. The reservoir behind the dam will irrigate another 406,000 ha by pumping for a total of 882,000 ha. The Atatürk Dam and

3294-471: The waters released from large-scale dams and HEPPs. Nearly 4,760 km (1,840 sq mi) of arable land in the Şanlıurfa - Harran and Mardin - Ceylanpınar plains in upper Mesopotamia is being irrigated via gravity-flow with water diverted from the Atatürk Dam through the Şanlıurfa Tunnels system, which consists of two parallel tunnels, each 26.4 km (16.4 mi) long and 7.62 m (25.0 ft) in diameter. The flow rate of water through

3355-476: The words of Arabic origin. The conservation of archaic phonological features of the Arabic borrowings furthermore suggests that Arabic-incorporated Persian was absorbed into pre-Ottoman Turkic at an early stage, when the speakers were still located to the north-east of Persia , prior to the westward migration of the Islamic Turkic tribes. An additional argument for this is that Ottoman Turkish shares

3416-580: The Şanlıurfa Tunnel system are two major components of the GAP project. Irrigation started in the Harran Plain in the spring of 1995. The impact of the irrigation on the economy of the region is significant. In ninety percent of the irrigated area, cotton is planted. Irrigation expansion within the Harran plains also increased Southeastern Anatolia's cotton production from 164,000 to 400,000 metric tons in 2001, or nearly sixty percent. With almost 50% share of

3477-406: Was expropriated. 70,000 families and 350,000 people were relocated by dam projects. It is estimated that 50,000 families and 250,000 people more will be affected in the future. Ottoman Turkish language Ottoman Turkish ( Ottoman Turkish : لِسانِ عُثمانی , romanized :  Lisân-ı Osmânî , Turkish pronunciation: [liˈsaːnɯ osˈmaːniː] ; Turkish : Osmanlı Türkçesi )

3538-403: Was not instantly transformed into the Turkish of today. At first, it was only the script that was changed, and while some households continued to use the Arabic system in private, most of the Turkish population was illiterate at the time, making the switch to the Latin alphabet much easier. Then, loan words were taken out, and new words fitting the growing amount of technology were introduced. Until

3599-474: Was reorganized in "Water Works General Directorate". The agency conducted studies on feasibility, planning, gauging and water level recording. Finally in 1954, the institution was named "General Directorate of State Hydraulic Works" and assigned to the Ministry of Public Works. State Hydraulic Works was reassigned later to the Ministry of Energy and Natural Resources. Since not a long time, the agency reports to

3660-594: Was the standardized register of the Turkish language in the Ottoman Empire (14th to 20th centuries CE). It borrowed extensively, in all aspects, from Arabic and Persian . It was written in the Ottoman Turkish alphabet . Ottoman Turkish was largely unintelligible to the less-educated lower-class and to rural Turks, who continued to use kaba Türkçe ("raw/vulgar Turkish"; compare Vulgar Latin and Demotic Greek ), which used far fewer foreign loanwords and

3721-475: Was transformed in three eras: In 1928, following the fall of the Ottoman Empire after World War I and the establishment of the Republic of Turkey , widespread language reforms (a part in the greater framework of Atatürk's Reforms ) instituted by Mustafa Kemal Atatürk saw the replacement of many Persian and Arabic origin loanwords in the language with their Turkish equivalents. One of the main supporters of
