There are two inscriptions in Tamil language displayed around the rim of the seal runs. தமிழ் நாடு அரசு ( Tamil Nadu arasu ) translating to "Government of Tamil Nadu" is inscribed on the top. Inscribed at the bottom is வாய்மையே வெல்லும் ( Vaymaiye Vellum ) which translates to "Truth Alone Triumphs" and derived from the words " Satyameva Jayate " in
150-496: A rock shelter under and behind the waterfall. Eventually, the outcropping , more resistant cap rock will collapse under pressure to add blocks of rock to the base of the waterfall. These blocks of rock are then broken down into smaller boulders by attrition as they collide with each other, and they also erode the base of the waterfall by abrasion , creating a deep plunge pool in the gorge downstream. Streams can become wider and shallower just above waterfalls due to flowing over
200-560: A day to build. The bottom of the boats are made waterproof by the use of hides , but sometimes with sheets of plastic. Use of plastics in the Hogenakkal vicinity, not just for boats, has been criticised due to problems with pollution. These boats are steered and propelled using a single paddle, making them unique. The coracles are locally called parisal in Tamil and teppa or harigolu in Kannada . Freshly caught fish are sold by
250-418: A distinct relationship with waterfalls since prehistory, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century, they have received increased attention as tourist destinations, sources of hydropower , and—particularly since the mid-20th century—as subjects of research. A waterfall
300-473: A long period of being fully formed, the water falling off the ledge will retreat, causing a horizontal pit parallel to the waterfall wall. Eventually, as the pit grows deeper, the waterfall collapses to be replaced by a steeply sloping stretch of river bed. In addition to gradual processes such as erosion, earth movement caused by earthquakes or landslides or volcanoes can lead to the formation of waterfalls. Waterfalls are an important factor in determining
350-480: A much higher extent than previously thought. Waterfalls also affect terrestrial species. They create a small microclimate in their immediate vicinity characterized by cooler temperatures and higher humidity than the surrounding region, which may support diverse communities of mosses and liverworts . Species of these plants may have disjunct populations at waterfall zones far from their core range. Waterfalls provide nesting cover for several species of bird, such as
400-465: A pioneering work on waterfalls. In 1942 Oscar von Engeln wrote of the lack of research on waterfalls: Waterfall sites more than any other geomorphic feature attract and hold the interest of the general public. Because they have such a popular approval waterfalls are not given serious attention by some students of systematic geomorphology. This attitude is not to be commended. Waterfalls are significant items for geomorphic investigation. As late as 1985
450-795: A role in many cultures, as religious sites and subjects of art and music. Many artists have painted waterfalls and they are referenced in many songs, such as those of the Kaluli people in Papua New Guinea . Michael Harner titled his study of the Jivaroan peoples of Ecuador The Jivaro: People of the Sacred Waterfalls. Artists such as those of the Hudson River School and J. M. W. Turner and John Sell Cotman painted particularly notable pictures of waterfalls in
500-603: A scholar felt that "waterfalls remain a very much neglected aspect of river studies". Studies of waterfalls increased dramatically in the second half of the 20th century. Numerous waterfall guidebooks exist, and the World Waterfall Database is a website cataloging thousands of waterfalls. Many explorers have visited waterfalls. European explorers recorded waterfalls they came across. In 1493, Christopher Columbus noted Carbet Falls in Guadeloupe , which

#1732773349653600-421: A waterfall continues to be debated. Waterfalls are sometimes interchangeably referred to as "cascades" and "cataracts", though some sources specify a cataract as being a larger and more powerful waterfall and a cascade as being smaller. A plunge pool is a type of stream pool formed at the bottom of a waterfall. A waterfall may also be referred to as a "foss" or "force". Waterfalls are commonly formed in

The legislature of Tamil Nadu was bicameral until 1986, when it was replaced by a unicameral legislature . The judiciary branch is led by a High Court ( Madras High Court ) led by a Chief Justice . The Governor is the de jure constitutional head of state while
700-824: Is also no agreement how to measure the height of a waterfall, or even what constitutes one. Angel Falls in Venezuela is the tallest waterfall in the world , the Khone Phapheng Falls in Laos are the widest, and the Inga Falls on the Congo River are the biggest by flow rate , while the Dry Falls in Washington are the largest confirmed waterfalls ever. The highest known subterranean waterfall
750-470: Is dominated by impacts of water-borne sediment on the rock, while downstream the erosion occurs more rapidly. As the watercourse increases its velocity at the edge of the waterfall, it may pluck material from the riverbed, if the bed is fractured or otherwise more erodible. Hydraulic jets and hydraulic jumps at the toe of a falls can generate large forces to erode the bed, especially when forces are amplified by water-borne sediment. Horseshoe-shaped falls focus
800-419: Is generally defined as a point in a river where water flows over a steep drop that is close to or directly vertical. In 2000 Mabin specified that "The horizontal distance between the positions of the lip and plunge pool should be no more than c 25% of the waterfall height." There are various types and methods to classify waterfalls. Some scholars have included rapids as a subsection. What actually constitutes
850-538: Is how Uguneer Kal(உகுநீர் கல்) became Hogenakkal. The name Hogenakal is derived from Kannada means ‘Smoky Rocks’. The river when falls on the rock below, the gushing force of water resembles like smoke emanating from the rocks. It is also called as Marikottayam by the people of Tamil Nadu. Hogenakkal falls is mentioned in Sangam Literature as Thalaineer aruvi (தலைநீர் அருவி). All the areas around this waterfalls are called Thalaineer Naadu (தலைநீர் நாடு). It

When warm and cold water meets by a gorge in the ocean, large underwater waterfalls can form as the cold water rushes to the bottom. The caprock model of waterfall formation states that the river courses over resistant bedrock , erosion happens slowly and
1000-837: Is the tenth largest Indian state by area . Tamil Nadu is divided into 38 districts , each of which is administered by a District Collector , who is an officer of the Indian Administrative Service (IAS) appointed to the district by the Government of Tamil Nadu. For revenue administration, the districts are further subdivided into 87 revenue divisions administered by Revenue Divisional Officers (RDO) which comprise 310 taluks administered by Tahsildars . The taluks are divided into 1349 revenue blocks called Firkas which consist of 17,680 revenue villages. The local administration consists of 15 municipal corporations , 121 municipalities and 528 town panchayats in

Hudson theorizes that they make good tourism sites because they are generally considered beautiful and are relatively uncommon. Activities at waterfalls can include bathing, swimming, photography, rafting , canyoning , abseiling , rock climbing , and ice climbing . Waterfalls can also be sites for generating hydroelectric power and can hold good fishing opportunities. Wealthy people were known to visit areas with features such as waterfalls at least as early as in Ancient Rome and China . However, many waterfalls were essentially inaccessible due to

Some waterfalls are also distinct in that they do not flow continuously. Ephemeral waterfalls only flow after a rain or a significant snowmelt. Waterfalls can also be found underground and in oceans. The geographer Andrew Goudie wrote in 2020 that waterfalls have received "surprisingly limited research." Alexander von Humboldt wrote about them in

Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf . Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had

The presence or absence of certain species can have cascading ecological effects, and thus cause differences in trophic regimes above and below waterfalls. Certain aquatic plants and insects also specialize in the environment of the waterfall itself. A 2012 study of the Agbokim Waterfalls , has suggested that they hold biodiversity to
1750-435: The erosion to a central point, also enhancing riverbed change below a waterfall. A process known as "potholing" involves local erosion of a potentially deep hole in bedrock due to turbulent whirlpools spinning stones around on the bed, drilling it out. Sand and stones carried by the watercourse therefore increase erosion capacity. This causes the waterfall to carve deeper into the bed and to recede upstream. Often over time,

European explorers often preferred to give waterfalls names in their own language; for instance, David Livingstone named Victoria Falls after Queen Victoria , though it was known by local peoples as Mosi-oa-Tunya. Many waterfalls have descriptive names which can come from the river they are on, places they are near, their features, or events that happened near them. Some countries that were colonized by European nations have taken steps to return names to waterfalls previously renamed by European explorers. Exploration of waterfalls continues;

The administration of the state government functions through various secretariat departments. Each department consists of
2200-426: The waterfall will recede back to form a canyon or gorge downstream as it recedes upstream, and it will carve deeper into the ridge above it. The rate of retreat for a waterfall can be as high as one-and-a-half metres per year. Often, the rock stratum just below the more resistant shelf will be of a softer type, meaning that undercutting due to splashback will occur here to form a shallow cave-like formation known as
2250-460: The way down. At Hogenakkal, the Kaveri, now a large river, drops and creates numerous waterfalls as the water cuts through the rocky terrain. In places the water falls as much as 20 m (66 ft) and is said to sound like continual thunder. The river carries sediment which makes the downriver land fertile. At Hogenakkal the river spreads out over a wide area of sandy beaches, then flows south to

Conversely, other waterfalls have seen significantly lower water levels as a result of diversion for hydroelectricity , such as the Tyssestrengene in Norway. Development of the areas around falls as tourist attractions has also destroyed the natural scene around many of them. Waterfalls are included on thirty-eight World Heritage Sites and many others are protected by governments. Waterfalls play

The pure Tamil name of Hogenakkal Falls is Uguneer Kal (உகுநீர் கல்). It was under the rule of Mysore Kingdom from 1652 to 1768 and during that period many Kannadas were employed and settled here in large numbers for tax collection work. Due to this reason, many Tamil names there became Kannada names .That
