Noyyal is a 180 km (110 mi)–long seasonal river in Western Tamil Nadu, India. It is a tributary of the Kaveri river. The river rises in the Vellingiri hills in the Western Ghats, and flows westwards through the cities of Coimbatore, and Tirupur, before draining into the Kaveri at Noyyal in Karur district. The river basin covers an area of 3,500 km2 (1,400 sq mi), which consists of 1,800 km2 (690 sq mi) of cultivable lands.
The river is seasonal, and dependent on the monsoon. An extensive tank system has been developed to store the river water and the overflow during monsoon. There are several check dams, and two larger dams–Aathupalayam and Orathuppalayam. Flowing through major urban areas, the river is highly polluted and faces significant ecological concern.
