Karnaphuli River

Karnaphuli ( Kôrnophuli; also spelt Karnafuli), the largest and most important river in Chittagong and the Chittagong Hill Tracts, is a wide river in the south-eastern part of Bangladesh. Originating from the Lushai hills  in Mizoram, India, it flows southwest through Chittagong Hill Tracts and Chittagong into the Bay of Bengal. A large hydroelectric power plant using Karnaphuli river was built in the Kaptai region during the 1960s. The mouth of the river hosts Chittagong's sea port, the main port of Bangladesh.
