Bharathappuzha, also known as the Ponnani River, is the second-longest river in Kerala, India, flowing through the districts of Palakkad and Thrissur. Originating from the Anamalai Hills in the Western Ghats, the river meanders for approximately 209 kilometers before emptying into the Arabian Sea at Ponnani. Bharathappuzha is a lifeline for the people living in its basin, providing water for irrigation, drinking, and transportation.
