formerly Gogra Nepali Karnali
River, northern India, Nepal, and China.
A major tributary of the Ganges , it rises as the Karnali in the Tibetan Himalayas and flows southeast into Nepal. Cutting south across the Siwalik Hills, it splits into two branches, to rejoin in India and form the Ghaghara proper. It flows southeast to enter the Ganges after a 600 mi (970 km) course. Together with the Ganges and its tributaries, it formed the vast alluvial plain of northern Bihar . Along its lower course it is also called the Sarju River and the Deoha.
