Sediment Transport and Sediment load

SEDIMENT TRANSPORT A flowing water in a channel, always tries to scour its surface. Silt, gravel or even larger boulders are first detached from its bed or banks, and then swept D/S by moving water. The phenomenon of detaching and then sweeping The silt or gravel from bed or banks is know is sediment transport. The phenomenon is of great economic importance. Following are some of the important works where sediment transport has its effects. The design and execution of flood control schemes is chiefly governed by the peak flood level. Which in turn depends upon the scour and deposition of sediment. Silting of channels and reservoirs also depends upon the sediment transport. Sediment deposited in rivers and harbours requires costly dredging. SEDIMENT LOAD The quantity of solids (silt) entering the channel, is know sediment load. It is a single important factor which controls the shape and cross-section of the…
