Ganges delta

region, India and Bangladesh
Also known as: Ganges-Brahmaputra delta

Ganges delta, region in West Bengal state, India, and Bangladesh. An area of about 220 miles (355 km) wide along the Bay of Bengal, it is covered by the network of streams forming the mouths of the Ganges (Ganga) and Brahmaputra rivers. In Bangladesh the Brahmaputra is joined by the Tista River and, from there to its junction with the Ganges, is known as the Jamuna River. The main streams, the Ganges and the Jamuna, unite to form the Padma River. The river farthest west that enters the Bay of Bengal is the Hugli River. Many smaller streams of the delta form a swamp region for about 160 miles (260 km) along the coast, known as the Sundarbans. The delta was struck in 1970 by one of history’s most devastating cyclones.
