The 'Bhavani' is the second largest river in Tamil Nadu, South India and a major tributary of the Kaveri River. The Bhavani is a 217 km. long perennial river fed mostly by the southwest monsoon and supplemented by the northeast monsoon. Its watershed drains an area of 6,200 km² spread over Tamil Nadu (87%), Kerala (9%) and Karnataka (4%). The main river courses through Coimbatore District and Erode districts of Tamil Nadu. About 90 per cent of the river’s water is used for agriculture irrigation. 6 million people live along its banks. Textile, leather, sugar, paper, slaughterhouse and distilling industries are located along the river and its tributaries at many points. Industrial, municipal and agricultural pollution of the river results in poor water quality and negative impacts on the health of people, plants and animals dependant on the river water.^[1]

Headwaters

The river's headwaters are on the eastern slopes of the Western Ghats range, in Attappadi Reserve Forest, in Palakkad district of Kerala state and the Kunda hills in the south west corner of the Nilgiri Hills of Tamil Nadu. The Upper Bhavani has been dammed creating the large Bhaktavalsalam Sagar reservoir. The river flows northwest, into Karnataka, draining the south slope of the Nilgiri Hills, flowing for a few kilometers southward it enters Kerala through a deep gorge and continues south for another 20 km, between two high, forested ridges till Mukkali.

Tributaries

12 major rivulets join Bhavani draining the southern Nilgiri slopes. The west and East Varagar tributaries coming from the Nilgiris are the largest and each have dams in Tamil Nadu. At Mukkali, Bhavani takes an abrupt 120° turn towards the northeast and flows for another 25 km through Attappady plateau and for 7 km. along the inter-State border
It gets reinforced by The Kunda river coming from the north. The Kunda drains an extensive part of the Nilgiris and forms the boundary between Kerala and Tamil Nadu for 5 km. It joins the Bhavani on its left flank in western Tamil Nadu at a place called Athikadavu. The Siruvani river a perennial stream of Coimbatore District and the Kodungarapallam river, flowing from the south and southeast respectively join the Bhavani at Koodappatti on the Kerala-Tamil Nadu border.
Thereafter Bhavani flows east along the base of Nilgiris and enters the plains near Bathra-Kaliamman Temple near Mettupalayam and is joined by the Coonoor River coming from Coonoor to the northwest. 30 km downstream, at Kottamangalam the Moyar River, a major tributary originating in Mudumalai National Park, flows in from the northwest, where it drains the valley between the northern slopes of the Nilgiris and the southern slopes of the Bilgiri Hills. After the Moyar it is blocked by the Lower Bhavani Dam, creating the Bhavanisagar reservoir near Sathyamangalam in Erode District.
The river continues east for over 160 km. through Erode District, traversing Gobichettipalayam and Bhavani taluks, before merging with the Cauvery. The Bhavani flows due east past the town of Sathyamangalam. Between Sathyamangalam and Gobichettipaalayam, a mini dam, the Kodivery dam feeds the Arakkankottai and Thadappalli canals constructed for agricultural purposes. Just a small distance before it joins cauvery a small barrage across the river was built by Kalingarayan in 1283 AD. to feed the 56-mile-long Kalingarayan irrigation canal. The Noyyal River joins at Aavudaiaaparai.
The Bhavani joins the Kaveri at the town of Bhavani. The Sangameswarar Temple at the confluence of the two rivers is an important pilgrimage spot.
