The Ganges delta is formed by the confluence of the Ganges (local name Padma or ''Pôdda''), Brahmaputra (Jamuna or ''Jomuna''), and Meghna rivers and their respective tributaries. The Ganges unites with the Jamuna (main channel of the Brahmaputra) and later joins the Meghna, finally flowing into the Bay of Bengal. Bangladesh is called the "Land of Rivers"; as it is home to over 57 trans-boundary rivers. However, this makes the resolution of water issues politically complicated, in most cases, as the country is a lower riparian state to India.
