Ganges Delta Ganges Delta The Ganges-Brahmaputra Delta (also known as the Brahmaputra Delta, the Sunderbans Delta or the Bengal Delta) is a river delta in the Bengal region of the Indian subcontinent, consisting of Bangladesh and the Indian state of West Bengal. It is the world's largest delta and empties into the Bay of Bengal the combined waters of several river systems, mainly those of the Brahmaputra river and the Ganges river.

River delta is called an inverted river delta. Sometimes a river divides into multiple branches in an inland area, only to rejoin and continue to the sea. Such an area is called an "inland delta", and often occurs on former lake beds. The Inner Niger Delta and Peace–Athabasca Delta are notable examples. The Amazon also has an inland delta before the island of Marajó, and the Danube has one in the valley on the Slovak-Hungarian border between Bratislava and Iža. In some cases, a river flowing into a flat arid area splits into channels that evaporate as it progresses into the desert.
