The flat delta lands of Bangladesh offer little resistance to the hydraulic forces of its rivers, particularly during periods of high flow. As a consequence, in many regions rivers such as the Jamuna run wide rather than deep: easily 10 km wide at places during high water, yet rarely in channels with sides deeper than two or three meters.
