The Amaravati River is a tributary of Kaveri River in Coimbatore District, Tamil Nadu state, South India. It is continuation of the Pambar and Chinnar rivers in Kerala.
The 175 km long Amaravati River begins at the Kerala/Tamil Nadu border at the bottom of Manjampatti Valley between the Annamalai Hills and the Palni Hills in Indira Gandhi Wildlife Sanctuary and National Park. It descends in a northerly direction through Amaravathi Reservoir and Amaravathi Dam at Amaravathinagar. It is joined by the Kallapuram River at the mouth of the Ajanda valley in Udumalaipettai. It joins with the Kaveri at Thirumukkudal, about 10km from Karur. The ancient name of the river is Anporunai and locals still use the name amrandhu, a derivative.[1]
This river irrigates over 60,000 acres (240 km2) of agricultural lands in Coimbatore, Erode and Karur districts.[2] The Amaravathi Dam has 4 Megawatts electric generating capacity installed. The Amaravathi River and its basin, especially in the vicinity of Karur, are heavily used for industrial processing water and waste disposal and as a result are severely polluted due to large amount of textile dyeing and bleaching units.[3]
