The prominent rivers of Bihar all originating from Nepal and entering into Bihar, are adversely affected sands-play resulting from flood. In Nepal these rivers have very steep slope and acquire scouring velocity. Thus the water flowing down carries a lot of silt and sand. Theses silts are deposited in the flood plains when the water enters into the plains of Bihar. This also reduces the depth of river and thus leads to diversion of river course.
