what is the distance of the flow of river cauvery in kodagu district?

Answer 1

The Kaveri River (Kannada: ಕಾವೇರಿ, Tamil: காவிரி, also spelled Cauvery or Kaveri in English) is one of the major rivers of India, which is considered sacred by Hindus. The river originates at Talakaveri in the Western Ghats in the state of Karnataka, flows generally south and east through Karnataka and Tamil Nadu and across the southern Deccan plateau through the southeastern lowlands, emptying into the Bay of Bengal through two principal mouths.

The Kaveri River basin is estimated to be 27,700 square miles with many tributaries including the Shimsa River, the Hemavati River, the Arkavathy River, Honnuhole River, Lakshmana Tirtha River, Kabini River, Bhavani River, the Lokapavani River, the Noyyal River and the Amaravati River. Rising in southwestern Karnataka state, it flows southeast some 475 mi (765 km) to enter the Bay of Bengal. East of the city of Mysore it forms the island of Sivasamudra, on either side of which are the scenic Sivasamudram Falls that descend about 320 ft (100 m). The river is the source for an extensive irrigation system and for hydroelectric power. The river has supported irrigated agriculture for centuries and served as the lifeblood of the ancient kingdoms and modern cities of South India.

After the river leaves the Kodagu hills and flows onto the Deccan plateau, it forms two islands, Srirangapatna and Shivanasamudra and. It also drops into the Hogenakal Falls just before it arrives in the towns of Hogenakal in the state of Karnataka and Srirangam in Tamil Nadu. At Sivasamudra Island the river drops 320 ft (98 m), forming the famous Sivasamudram Falls known separately as Gagana Chukki and Bhara Chukki. India's first hydroelectric plant (built in 1902) was on the left falls and supplied power to the city of Bangalore. In 1906, Bangalore became the first city in Asia to be fully electrified and to have electric street lights.

The river enters Tamil Nadu in all splendor after leaving the great falls in Hogenakal. From there it meanders into the southern plains. It is in the composite district of Thanjavur that the rich, silt-laden river delta region is formed before it empties into the Bay of Bengal through its two mouths.

Kaveri in Karnataka

In its course through Karnataka, the channel is interrupted by twelve "anicuts" (dams) for the purpose of irrigation. From the anicut at Madadkatte, an artificial channel is diverted a distance of 72 miles, irrigating an area of 10,000 acres (40 km²), and ultimately bringing its water supply to the town of Mysore. Near Srirangapatna, there is an aqueduct, the Bangara Doddi Nala, which was constructed in the 17th century by the Wodeyar maharaja of Mysore, Ranadhira Kantirava, in memory of his favorite consort. It is said to be the only aqueduct where the water from a river, dammed upstream, is carried by the aqueduct over the very same river few miles downstream [citation needed]. This aqueduct also served as a motorable bridge till 1964. In addition to providing many ancient and modern canals with water from the river for irrigational purposes, the Kaveri also serves as the main drinking water source for many towns and villages. The cities of Bangalore and Mysore depend almost entirely on the Kaveri for their drinking water supply.

The great Hogenakal falls marks the exit of kaveri from karnataka.

Kaveri in Tamil Nadu
After entering Tamil Nadu, the Kaveri flows into Stanley Reservoir, and exits the reservoir at Mettur Dam. The Kaveri forms the boundary between the Erode District and the Salem district. The Bhavani River joins the Kaveri at the town of Bhavani, where the Sangameswara Temple, an important pilgrimage spot in southern India, was built at the confluence of the two rivers. The Amaravati River joins the Kaveri at a place called Tirumukkudalur near Karur.

Sweeping past the historic rock of Tiruchirapalli, it breaks into two channels (at the island of Srirangam), which enclose between them the delta of Thanjavur (Tanjore), considered both the "rice bowl" and garden spot of southern India. The northern channel is called the Kollidam (Coleroon). The other channel keeps the name of Kaveri and empties into the Bay of Bengal at Poompuhar, a few hundred miles south of Chennai in Madras. On the seaward face of its delta are the seaports of Nagapattinam and Karikal.

The most ancient surviving irrigation work is the Grand Anicut or Kallanai, a massive dam of unhewn stone, 328 meters (1080 feet) long and 20 meters (60 feet) wide, spanning the stream of the Kaveri proper. The area irrigated by the ancient tank system was 69,000 acres[citation needed] (280 km²), which by the early 20th century increased to about 1,000,000 acres[citation needed] (4,000 km²) and later drastically reduced after the construction of other dams upstream[citation needed].

The chief 19th century work is the anicut across the Kollidam which is 2250 ft. long, and was constructed by Sir Arthur Cotton between 1836 and 1838. The Grand Anicut is the most ancient surviving irrigation work in the Kaveri River delta.The dam is still in excellent condition, and served as an exemplary model to later engineers.
