Which of the following pairs of dams and their corresponding rivers in Kerala is correctly matched?

💡 Solution & Explanation

The Idukki Dam, an arch dam, is constructed across the Periyar River between the Kuravan and Kurathi hills. Banasura Sagar Dam is built across the Karamanathodu River, a tributary of the Kabani River, not the Pamba. Mullaperiyar Dam is situated on the Periyar River, not the Bharathappuzha. Cheruthoni Dam is also part of the Idukki hydro-electric project across the Cheruthoni River, a tributary of the Periyar, not the Chalakudy River. These dams form the backbone of Kerala's hydroelectric power generation.
