Summary: | Erosional pattern of fine cohesive sediment must be defined to predict the transport
model in estuarial water Resistance to erosion is largely dependent on physicochemical
properties of sediment and fluid, as well as the interparticle bond which is
characterized by shear strength. Successively incremental flow-induced bed shear
stress is applied to initiate layer by layer erosion of soft cohesive sediment deposit to
determine the rate of erosion. A decrease in erosion rate is observed at the end of
each time step. This behavior is due to the increasing shear strength with depth. The
rate of erosion was found to vary exponentially with cubic root of excess bed shear
stress |
