Statement: Bed load transportation
Abstract: A close up of bed load transportation with a still camera frame. 50g/m/s 7.0mm d50 50g/m/s 0.20mm d50 Grain Size ratio = 35
Theory
Bed load transportation is a function of the fluid force per area, or shear stress on the stream bed. Shear stress is proportional to the specific weight of the fluid, the depth and the surface slope of the fluid. The frictional resisting force is proportional to the specific weight of the sediment and the diameter of the sediment.
