Statement: Bed Load Transport
Abstract: Bed load transport due to moving water flowing over the bedload surface from multiple angles. All scenes are slowed down. The first is a mixture of 95% sand and 5% gravel. The second is a mixture of 80% sand and 20% gravel. The third is the same mixture.
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.
