Bhatkal lies on National Highway 66 , which runs between Mumbai and Kanyakumari , and has Bhatkal railway station which is one of the major railway stations along the Konkan Railway line, which runs between Mumbai and Mangalore . Bhatkal was named after Jain Grammarian, Bhattakalanka, who hailed from Hadwalli village,

152-534: A navy and some form of coast guard . Coasts, especially those with beaches and warm water, attract tourists often leading to the development of seaside resort communities. In many island nations such as those of the Mediterranean , South Pacific Ocean and Caribbean , tourism is central to the economy . Coasts offer recreational activities such as swimming, fishing, surfing, boating, and sunbathing . Growth management and coastal management can be

228-478: A challenge for coastal local authorities who often struggle to provide the infrastructure required by new residents, and poor management practices of construction often leave these communities and infrastructure vulnerable to processes like coastal erosion and sea level rise . In many of these communities, management practices such as beach nourishment or when the coastal infrastructure is no longer financially sustainable, managed retreat to remove communities from

304-701: A corporation in 1668. The Keladi Nayakas invited Kazi Mahmoud, who was a grandson of the Chief Kazi of the Adil Shahi kingdom of Bijapur, to settle in Bhatkal in the year 1670. The revenue of Tenginagundi village was given to Kazi Mahmoud. The Kazi family of Bhatkal is popularly known as the Temunday Family due to the ownership of lands in Tenginagundi. Many Nawayath Muslims were appointed to

380-805: A good relationship with the Bijapur kings. The kings of one branch of the Saluva Dynasty of Vijayanagar ruled Gerusoppe while another dynasty ruled Haduvalli. King Immadi Devaraya (1515–50) of Gerusoppe, fought against the Portuguese. After his defeat in a fierce battle near MadaGoa in 1542, the Portuguese burnt down his capital Bhatkala. His wife Chennadevi was the elder sister of Chennabhairadevi. The Portuguese captain Alfonso D'Souza attacked Bhatkala , defeated Chennadevi and burnt Bhatkala, accusing her of sheltering non-cartaged Mohammedan ships in

456-655: A much higher capacity for carbon sequestration than many terrestrial ecosystems , and as such can play a critical role in the near-future to help mitigate climate change effects by uptake of atmospheric anthropogenic carbon dioxide . However, the economic importance of coasts makes many of these communities vulnerable to climate change , which causes increases in extreme weather and sea level rise, as well as related issues like coastal erosion , saltwater intrusion , and coastal flooding . Other coastal issues, such as marine pollution , marine debris , coastal development, and marine ecosystem destruction, further complicate

532-653: A proper name to the coast of the Ligurian Sea , in the form riviera ligure , then shortened to riviera . Historically, the Ligurian Riviera extended from Capo Corvo (Punta Bianca) south of Genoa , north and west into what is now French territory past Monaco and sometimes as far as Marseilles . Today, this coast is divided into the Italian Riviera and the French Riviera , although

608-435: A provider of sediment for coastlines of tropical islands. Like the ocean which shapes them, coasts are a dynamic environment with constant change. The Earth 's natural processes, particularly sea level rises , waves and various weather phenomena, have resulted in the erosion , accretion and reshaping of coasts as well as flooding and creation of continental shelves and drowned river valleys ( rias ). More and more of

684-456: A shoreline configuration. Swash is the shoreward flow after the break, backwash is the water flow back down the beach. The relative strength of flow in the swash and backwash determines what size grains are deposited or eroded. This is dependent on how the wave breaks and the slope of the shore. Depending on the form of the breaking wave, its energy can carry granular material up the beach and deposit it, or erode it by carrying more material down

760-425: A slightly different way in discussions of legal and economic boundaries (see territorial waters and international waters ) or when considering the geography of coastal landforms or the ecological systems operating through the continental shelf ( marine coastal ecosystems ). The research on coastal waters often divides into these separate areas too. The dynamic fluid nature of the ocean means that all components of

836-709: A town named 'Bhattakala' for his disciple, the king Devaraya. The rulers of Haduvalli were from the Suluva (Jain) Dynasty, and the Bhattakalanka was the last and well-known grammarian of Haduvalli as per the Biligi Ratnatraya Basadi inscription. At the time of Narasimha Deva Raya , he ended the tyranny of Virupaksha and re-established the friendship between the Nawayath. On 28 August 1502, Vasco de Gama -led Portuguese forces attacked and burned

912-593: A town on the state highway toward Jog Falls, Shimoga. It was also known as Susagadi, and Manipur in Sanskrit. The Hamilton referred to it as Batuculla, which means 'Round town'. Some have claimed that Marathi influence is responsible for the word's derivation. According to Deshabandhu M. Shanker Linge Gowda, when the military leaders of the Patwardhan family under the Peshwas used to periodically invade and pillage

988-529: A wide range of sessile animals (e.g. mussels , starfish , barnacles ) and various kinds of seaweeds . In physical oceanography , a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 m (3.3–164.0 ft). According to an atlas prepared by

1064-541: Is a coastline that has experienced a fall in sea level, because of either a global sea-level change, or local uplift. Emergent coastlines are identifiable by the coastal landforms , which are above the high tide mark, such as raised beaches . In contrast, a submergent coastline is one where the sea level has risen, due to a global sea-level change, local subsidence , or isostatic rebound . Submergent coastlines are identifiable by their submerged, or "drowned" landforms, such as rias (drowned valleys) and fjords According to

1140-528: Is connected to marine pollution which can occur from a number of sources: Marine debris (garbage and industrial debris); the transportation of petroleum in tankers , increasing the probability of large oil spills ; small oil spills created by large and small vessels, which flush bilge water into the ocean. Marine pollution occurs when substances used or spread by humans, such as industrial , agricultural and residential waste , particles , noise , excess carbon dioxide or invasive organisms enter

1216-533: Is connected to other cities and states in India by roads and railways. The National Highway 66 (India) crosses the town, which had a major impact on its development. Under the Konkan Railway , many trains run day and night to and from the town. The Bhatkal railway station has two platforms. The nearest airports to Bhatkal are Mangalore International Airport and Goa-Dabolim International Airport . The town has one large, one medium, and one small fishing port. As per

1292-415: Is extremely important to geologists. These provide vital clues for reconstructing the geography of ancient continents ( paleogeography ). The locations of these beds show the extent of ancient seas at particular points in geological time, and provide clues to the magnitudes of tides in the distant past. Sediments deposited in the shoreface are preserved as lenses of sandstone in which the upper part of

1368-408: Is more important. Macrotidal coasts lack barrier islands and lagoons , and are characterized by funnel-shaped estuaries containing sand ridges aligned with tidal currents. Wave action is much more important for determining bedforms of sediments deposited along mesotidal and microtidal coasts than in macrotidal coasts. Waves erode coastline as they break on shore releasing their energy; the larger

1444-423: Is moved along the coastline by the waves. This forms an abrasion or cliffed coast . Sediment deposited by rivers is the dominant influence on the amount of sediment located in the case of coastlines that have estuaries. Today, riverine deposition at the coast is often blocked by dams and other human regulatory devices, which remove the sediment from the stream by causing it to be deposited inland. Coral reefs are

1520-407: Is shayya biryani, made from vermicelli  (shayyo) instead of rice. The dishes used for breakfast are theek and goad thari (sweet and spicy semolina), gavan or thalla shayyo (wheat or rice vermicelli), varieties of appo  (pancakes), fau ( poha ), theek and goad khubus (sweet and spicy bread), masala poli (heavy spiced paratha), gavan poli (wheat paratha), and puttu (steamed cakes). Bhatkal

1596-412: Is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the fractal curve –like properties of coastlines; i.e., the fact that a coastline typically has a fractal dimension . Although the "paradox of length" was previously noted by Hugo Steinhaus , the first systematic study of this phenomenon was by Lewis Fry Richardson , and it

1672-462: The Aegean Sea . The following articles describe some coastal landforms: "Coastal waters" (or "coastal seas") is a rather general term used differently in different contexts, ranging geographically from the waters within a few kilometers of the coast, through to the entire continental shelf which may stretch for more than a hundred kilometers from land. Thus the term coastal waters is used in

1748-554: The Portuguese ), was the 16th-century Jain queen of Nagire province under the Vijayanagara Empire . She was officially known as Mahamandaleshwari Rani Chennabhairadevi . She is regarded as being the longest ruling queen in Indian history, from 1552 to 1606, a period of 54 years. She is also known for her wars against the Portuguese in 1559 and 1570, which she won, which helped to start commercial relationships with

1824-456: The US EPA considers this region to extend much further offshore. "Coastal waters" has specific meanings in the context of commercial coastal shipping , and somewhat different meanings in the context of naval littoral warfare . Oceanographers and marine biologists have yet other takes. Coastal waters have a wide range of marine habitats from enclosed estuaries to the open waters of

1900-617: The United Nations , about 44% of the human population lives within 150 km (93 mi) of the sea as of 2013 . Due to its importance in society and its high population concentrations, the coast is important for major parts of the global food and economic system, and they provide many ecosystem services to humankind. For example, important human activities happen in port cities. Coastal fisheries (commercial, recreational, and subsistence) and aquaculture are major economic activities and create jobs, livelihoods, and protein for

1976-686: The Western Interior Seaway , a shallow sea that flooded central North America during the late Cretaceous Period (about 100 to 66 million years ago). These are beautifully exposed along the Book Cliffs of Utah and Colorado . The following articles describe the various geologic processes that affect a coastal zone: Larger animals that live in coastal areas include puffins , sea turtles and rockhopper penguins , among many others. Sea snails and various kinds of barnacles live on rocky coasts and scavenge on food deposited by

2052-469: The ocean and cause harmful effects there. The majority of this waste (80%) comes from land-based activity, although marine transportation significantly contributes as well. It is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Since most inputs come from land, either via

2128-596: The ocean . Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping . Naturally occurring debris, such as driftwood and drift seeds , are also present. With the increasing use of plastic , human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10%) and majority of large plastic in

Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen , silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff , wind-blown debris , and dust. These nonpoint sources are largely due to runoff that enters

2280-433: The 2011 India census , Bhatkal Taluk had a population of approximately 161,576 out of which, 49.98% were males and 50.02% were females. Bhatkal has an average literacy rate of 74.04%, with 78.72% and 69.36% of male and female literacy, respectively. Around 11% of the town's total population is under age 5. Scheduled Castes constitute 8.87% and Scheduled Tribes constitute 5.67% of the total population. Bhatkal municipality

2356-773: The French use the term "Riviera" to refer to the Italian Riviera and call the French portion the "Côte d'Azur". As a result of the fame of the Ligurian rivieras, the term came into English to refer to any shoreline, especially one that is sunny, topographically diverse and popular with tourists. Such places using the term include the Australian Riviera in Queensland and the Turkish Riviera along

2432-792: The Ghats were under the rule of Chennabhairadevi. Pepper , cinnamon , nutmeg , ginger and sandalwood were exported to Europe during her reign. The remains of the Mirjan Fort and Kanur Fort from her reign can still be seen. She built the Chaturmukha Basadi in Karkala in 1562. The queen gave shelter in her kingdom to the Saraswat Brahmins and Konkanis who sought refuge in Chennabhairadevi's kingdom to escape

2508-478: The Manipura kingdom, they called it Vatkul, which means "hills around the town," because the Manipura fort was located in a valley surrounded by hills. In slang, Vatkul has now evolved into Bhatkal. The Bhatkal term originated and can be found in one of the oldest manuscripts of Nawayathi from 1100 A.H. (or 1688 A.D.) by Akhun Seedy Mohammed. The author mentions the old name for bhatkal as Abadaqilla (آبادقلعه). But

She earned the title "The Queen of Pepper" from the Portuguese, as she exported a great amount of pepper and other spices to European and Arab regions through the ports of Bhatkal and Honnavar . Nagire province, also known as the province of Gerusoppa , was one of the small provinces under the control of the king of Vijayanagara, known as Mahamandala. The province followed

2660-546: The United Nations has declared 2021–2030 the UN Decade on Ecosystem Restoration , but restoration of coastal ecosystems has received insufficient attention. Since coasts are constantly changing, a coastline's exact perimeter cannot be determined; this measurement challenge is called the coastline paradox . The term coastal zone is used to refer to a region where interactions of sea and land processes occur. Both

Coastal town Coasts are important zones in natural ecosystems , often home to a wide range of biodiversity . On land, they harbor important ecosystems such as freshwater or estuarine wetlands , which are important for bird populations and other terrestrial animals . In wave-protected areas, they harbor salt marshes , mangroves or seagrasses , all of which can provide nursery habitat for fin fish , shellfish , and other aquatic animals . Rocky shores are usually found along exposed coasts and provide habitat for

2812-555: The administrative positions. The families of these nobles from Nawayath still use their surnames as Ikkeri and are mainly settled in and around Bhatkal. The Golden Kalasa on the dome of Bhatkal Jamia Masjid, popularly known as 'Chinnada Palli' meaning 'Golden Mosque' is believed to be a generous gift from Keladi rulers. From the Keladi rulers, Bhatkal passed on to the Mysore Sultanate . Hyder Ali and Tipu Sultan made Bhatkal

2888-571: The average sea level rose by 15–25 cm (6–10 in), with an increase of 2.3 mm (0.091 in) per year since the 1970s. This was faster than the sea level had ever risen over at least the past 3,000 years. The rate accelerated to 4.62 mm (0.182 in)/yr for the decade 2013–2022. Climate change due to human activities is the main cause. Between 1993 and 2018, melting ice sheets and glaciers accounted for 44% of sea level rise , with another 42% resulting from thermal expansion of water . International attention to address

2964-417: The average wind wave and swell conditions are relatively mild. Low energy coasts typically change slowly, and tend to be depositional environments. High energy coasts are exposed to the direct impact of waves and storms, and are generally erosional environments. High energy storm events can make large changes to a coastline, and can move significant amounts of sediment over a short period, sometimes changing

3040-547: The banks of Sharavathi river and extended from South Goa to Malabar. Gerusoppa served as the capital of the province. The province was rich in spices and had important ports on the west coast, such as Bhatkal, Honnavar and Karwar. Jog Falls, India's second highest plunge waterfall is located near Gerusoppa. In fact locals call Jog Falls 'Gerusoppa Falls' after the province. The provinces of Bilgi and Keladi were Nagire's neighbours and often tried to conquer Nagire to extend their kingdoms. To counter them, Chennabhairadevi developed

3116-461: The coast of Wales and other countries. Coastal fish , also called inshore fish or neritic fish, inhabit the sea between the shoreline and the edge of the continental shelf . Since the continental shelf is usually less than 200 metres (660 ft) deep, it follows that pelagic coastal fish are generally epipelagic fish , inhabiting the sunlit epipelagic zone . Coastal fish can be contrasted with oceanic fish or offshore fish , which inhabit

3192-812: The coast. Estuarine and marine coastal ecosystems are both marine ecosystems . Together, these ecosystems perform the four categories of ecosystem services in a variety of ways: The provisioning services include forest products, marine products, fresh water , raw materials, biochemical and genetic resources. Regulating services include carbon sequestration (contributing to climate change mitigation ) as well as waste treatment and disease regulation and buffer zones. Supporting services of coastal ecosystems include nutrient cycling , biologically mediated habitats and primary production . Cultural services of coastal ecosystems include inspirational aspects, recreation and tourism , science and education. According to one principle of classification, an emergent coastline

3268-567: The continental shelf. Similarly, the term littoral zone has no single definition. It is the part of a sea , lake , or river that is close to the shore . In coastal environments, the littoral zone extends from the high water mark , which is rarely inundated, to shoreline areas that are permanently submerged . Coastal waters can be threatened by coastal eutrophication and harmful algal blooms . The identification of bodies of rock formed from sediments deposited in shoreline and nearshore environments (shoreline and nearshore facies )

3344-804: The conversion by the Portuguese. A Jain Rani helped to build and renovate many Shaiva, Vaishnava and Shakti temples. The Rani also assisted in the renovation of Yoganarasimha Swami Temple and Vardhamana Basadi in Baderu or Venupura. Abhinava Bhattakalanka of the Swadi Digambara Jain Math, author of the grammar book "Karnataka Shabdanushasana", was under the patronage of this queen. "Between Batikala (Bhatkala) and Goa there are places called Onor (Kanur), Marzen (Mirjan) and Ankola. I have heard that they export 5000 cruzados (a fifteenth century Portuguese gold coin) of pepper annually. These places were under

3420-555: The deep seas beyond the continental shelves. Many coastal areas are famous for their kelp beds. Kelp is a fast-growing seaweed that can grow up to half a meter a day in ideal conditions. Mangroves , seagrasses , macroalgal beds, and salt marsh are important coastal vegetation types in tropical and temperate environments respectively. Restinga is another type of coastal vegetation. Coasts also face many human-induced environmental impacts and coastal development hazards . The most important ones are: The pollution of coastlines

3496-789: The human uses of the coast and threaten coastal ecosystems. The interactive effects of climate change, habitat destruction , overfishing , and water pollution (especially eutrophication ) have led to the demise of coastal ecosystem around the globe. This has resulted in population collapse of fisheries stocks, loss of biodiversity , increased invasion of alien species , and loss of healthy habitats. International attention to these issues has been captured in Sustainable Development Goal 14 "Life Below Water", which sets goals for international policy focused on preserving marine coastal ecosystems and supporting more sustainable economic practices for coastal communities. Likewise,

One of Tipu's wives was from Bhatkal. Bhatkal later came into the hands of the British Empire in 1799 after they defeated Tipu. In 1862, Bhatkal was annexed to the Bombay Presidency . With the reorganization of

3648-410: The majority of coastal human populations. Other coastal spaces like beaches and seaside resorts generate large revenues through tourism . Marine coastal ecosystems can also provide protection against sea level rise and tsunamis . In many countries, mangroves are the primary source of wood for fuel (e.g. charcoal ) and building material. Coastal ecosystems like mangroves and seagrasses have

3724-673: The margins of the continental shelves , make up about 7 percent of the Earth's oceans, but at least 85% of commercially harvested fish depend on coastal environments during at least part of their life cycle. As of October 2010, about 2.86% of exclusive economic zones were part of marine protected areas . The definition of coasts varies. Marine scientists think of the "wet" (aquatic or intertidal ) vegetated habitats as being coastal ecosystems (including seagrass, salt marsh etc.) whilst some terrestrial scientists might only think of coastal ecosystems as purely terrestrial plants that live close to

3800-587: The microplastics go through the water filtration system and into the ocean, but because of their small size they are likely to escape capture by the preliminary treatment screens on wastewater plants. These beads are harmful to the organisms in the ocean, especially filter feeders, because they can easily ingest the plastic and become sick. The microplastics are such a concern because it is difficult to clean them up due to their size, so humans can try to avoid using these harmful plastics by purchasing products that use environmentally safe exfoliates. Between 1901 and 2018,

3876-480: The middle and are cylindrical in shape. Bhatkali cuisine is a blend of Arabian and Konkan cuisine. Bhatkali biryani is an integral part of the Nawayath cuisine and a specialty of Bhatkal, prepared with basmati rice that has been spiced with full garam masala and saffron. Separately, pieces of mutton, chicken, fish, or prawns are cooked. Some people even refer to it as a layered korma and rice meal with fried onions, curry, or mint leaves on top. Another type of biryani

3952-507: The more resistant rocks erode more slowly, remaining as headlands or outcroppings . Parts of a coastline can be categorised as high energy coast or low energy coast. The distinguishing characteristics of a high energy coast are that the average wave energy is relatively high so that erosion of small grained material tends to exceed deposition, and consequently landforms like cliffs, headlands and wave-cut terraces develop. Low energy coasts are generally sheltered from waves, or in regions where

4028-441: The ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution , bilge pollution , atmospheric pollution and, potentially, deep sea mining . Marine debris , also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or

4104-485: The oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish , seabirds , marine reptiles , and marine mammals , as well as to boats and coasts. A growing concern regarding plastic pollution in the marine ecosystem is the use of microplastics. Microplastics are beads of plastic less than 5 millimeters wide, and they are commonly found in hand soaps, face cleansers, and other exfoliators. When these products are used,

4180-722: The port and for not paying Kappa as per the agreement with the Portuguese. After her elder sister, Chennabhairadevi got the power of Gerusoppe along with Haduvalli. Mahamandaleshwari Chennabhairadevi was praised by historians for being a good administrator. She reigned from 1552 to 1606. Bhairadevi built Mirjan Fort on the banks of the Aghanashini river, using it to control the pepper business. Chennabhairadevi's kingdom consisted of Dakshina Goa, Uttara Kannada, Dakshina Kannada, Bhatkala, Malpe, Honnavara, Mirjan, Ankola, Byndur, and Karwar. Along with this coast, Bharangi, Marabidi, Karuru, Hannar, Bidanur, Saulnadu, Avinahalli regions on

4712-401: The seashore (see also estuaries and coastal ecosystems ). While there is general agreement in the scientific community regarding the definition of coast, in the political sphere, the delineation of the extents of a coast differ according to jurisdiction . Government authorities in various countries may define coast differently for economic and social policy reasons. The coastline paradox

4788-427: The second principle of classification, a concordant coastline is a coastline where bands of different rock types run parallel to the shore. These rock types are usually of varying resistance , so the coastline forms distinctive landforms, such as coves. Discordant coastlines feature distinctive landforms because the rocks are eroded by the ocean waves . The less resistant rocks erode faster, creating inlets or bay ;

4864-404: The slope than up it. Steep waves that are close together and break with the surf plunging down onto the shore slope expend much of their energy lifting the sediment. The weak swash does not carry it far up the slope, and the strong backwash carries it further down the slope, where it either settles in deeper water or is carried along the shore by a longshore current induced by an angled approach of

Folk sports like Kambala and folk arts like Yakshagana are also popular. Unlike other states, Nawayathi men wear lungis , which are stitched in

5016-758: The terms coast and coastal are often used to describe a geographic location or region located on a coastline (e.g., New Zealand's West Coast , or the East , West , and Gulf Coast of the United States .) Coasts with a narrow continental shelf that are close to the open ocean are called pelagic coast , while other coasts are more sheltered coast in a gulf or bay . A shore , on the other hand, may refer to parts of land adjoining any large body of water, including oceans (sea shore) and lakes (lake shore). The Earth has approximately 620,000 kilometres (390,000 mi) of coastline. Coastal habitats, which extend to

5168-487: The wave the more energy it releases and the more sediment it moves. Coastlines with longer shores have more room for the waves to disperse their energy, while coasts with cliffs and short shore faces give little room for the wave energy to be dispersed. In these areas, the wave energy breaking against the cliffs is higher, and air and water are compressed into cracks in the rock, forcing the rock apart, breaking it down. Sediment deposited by waves comes from eroded cliff faces and

5244-476: The wave-front to the shore. These waves which erode the beach are called destructive waves. Low waves that are further apart and break by spilling , expend more of their energy in the swash which carries particles up the beach, leaving less energy for the backwash to transport them downslope, with a net constrictive influence on the beach. Riviera is an Italian word for "shoreline", ultimately derived from Latin ripa ("riverbank"). It came to be applied as

5320-407: The waves surge up the river estuaries from the ocean. Geologists classify coasts on the basis of tidal range into macrotidal coasts with a tidal range greater than 4 m (13 ft); mesotidal coasts with a tidal range of 2 to 4 m (6.6 to 13 ft); and microtidal coasts with a tidal range of less than 2 m (7 ft). The distinction between macrotidal and mesotidal coasts

5396-469: The whole ocean system are ultimately connected, although certain regional classifications are useful and relevant. The waters of the continental shelves represent such a region.

Many major cities are on or near good harbors and have port facilities. Some landlocked places have achieved port status by building canals . Nations defend their coasts against military invaders, smugglers and illegal migrants. Fixed coastal defenses have long been erected in many nations, and coastal countries typically have

5624-441: Was expanded upon by Benoit Mandelbrot . Tides often determine the range over which sediment is deposited or eroded. Areas with high tidal ranges allow waves to reach farther up the shore, and areas with lower tidal ranges produce deposition at a smaller elevation interval. The tidal range is influenced by the size and shape of the coastline. Tides do not typically cause erosion by themselves; however, tidal bores can erode as

5700-466: Was founded in 1890 and was part of Honnavar Taluk ; a decade later, in 1903, the income was 6500 rupees. Two small mosques and two large mosques existed within the town.
