Analysis for the Cause of Sharp Cutoff of Water and Sediment in He-Long Reach the Yellow River Middle Area

Abstract:

This paper analyzes the circumstance of the sharp cutoff of water and sediment in He-Long reach recently, discusses the cause of the change of water and sediment. The study shows that, the change of underling surface and the rainfall without runoff are the primary reason for the sharp cutoff of water and sediment, if the rainfall condition changes, especially under the rainstorm which in the large area, with high strength and last for long time, the accumulated and secluded sediments could make the sediment yield increase sharply, the circumstance of sharp cutoff of water and sediment would change.
