Transboundary river

A transboundary river is a river that crosses at least one political border, either a border within a nation or an international boundary. Bangladesh has the highest number of these rivers, including two of the world's largest rivers, the Ganges and the Brahmaputra.
Transboundary rivers of Bangladesh.
Bangladesh has at least 58 major rivers that enter the nation from India or Myanmar. The hydrologic and political effects of rivers that cross significant boundaries are enormous. Rivers have positive effects in that they carry a significant amount of sediment, which aids in building land in estuarine regions. However this sediment raises the height of riverbeds, thereby causing flooding. International conventions governing water sharing have led to complex political disputes.
