Water ways
Country made crafts are the most widely used carriers on the rivers. These carry passengers and merchandise on a large scale. The landscape of Bangladesh is dominated by about 250 major rivers which flow essentially north-south. The alluvial flood plain formed by these rivers covers most of the country. Wherever there is a river and a village, a launch or steamer will ply for trade.
Bangladesh Inland Water Transport Authority (BIWTA) has been established by the government for maintenance of navigability of ports and channels while the state-owned BIWTC provides passenger and cargo services in inland waterways and coastal areas of the country.
