river Kaveri is the lifeblood as both Karnataka and tamilnadu analyse
Answers
Answer:
In Karnataka the river bifurcates twice, forming the sacred islands of Srirangapatnam and Sivasamudram, 50 miles (80 km) apart. Around Sivasamudram are the scenic Sivasamudram Falls, comprising two series of rapids, Bhar Chukki and Gagana Chukki, plunging a total of 320 feet (100 metres) and reaching a width of 1,000 feet (300 metres) in the rainy season. The falls supply hydroelectric power to Mysuru , Bangalore, and the Kolar Gold Fields, more than 100 miles (160 km) away.
Upon entering Tamil Nadu, the Kaveri continues through a series of twisted wild gorges until it reaches Hogenakal Falls and flows through a straight, narrow gorge near Salem. There the Mettur Dam, 5,300 feet (1,620 metres) long and 176 feet (54 metres) high, impounds a lake (Stanley Reservoir) of 60 square miles (155 square km). The Mettur Project, completed in 1934, created an important agricultural and industrial area by improving irrigation and providing hydropower.
Important:
The river is also called the life support system of Coorg as it's the source of an extensive irrigation system and the generation of hydroelectric power. The Cauvery has supported irrigated agriculture for centuries together and served as the lifeblood of both ancient kingdoms and modern cities of Southern India
