Limited experiments on the initiation of motion of sand grains in the annular channel-ring system showed a reasonable agreement with Shields. curve for incipient motion. The resuspension rates of stratified beds continuously decrease, and may even become zero, as the depth of erosion increases. On the other hand, the erosion rates of uniform beds remain constant. This is in agreement with earlier observations on natural bay deposits. The nondimensional plot of the erosion rate against the bed shear stress for uniform beds agrees with earlier results based on soils with drastically different mineralogical composition.
