Kalingarayan Canal
 Kalingarayan Canal is a 90-mile long irrigation canal in the Erode district Tamil Nadu India. It was constructed by Kongu chieftain Kalingarayan and was completed in 1283. It starts with Kalingarayan dam on River Bhavani near Bhavani and flows through Erode before terminating near Kodumudi. Recently the canal has suffered from pollution. In 2007 a 12-crore (120 million) rupee programme to develop the canal was announced funded by the National Bank for Agriculture and Rural Development.
