抄録

As a basis for sediment yield estimation from bare slopes, the mechanism of erosion and sedi.Ment transport on the sandy bed with some bentonite is studied. Through experiments, thefollowing are found and partly explained by a simplified model:Under a constant tractive force, the bed degrades uniformly and sediment discharge increasesdownstream, until it reaches the transport capacity of the flow.Rate of erosion is proportional to shear velocity, when their values are large, but not so whensmall.Critical shear stress for cohesive material varies not only with its composition but with its fore-going and existing conditions.
