PHYSICALLY BASED FORMULATION OF COHESIVE SEDIMENTRESUSPENSION

In most widely used resuspension formulations, the user calculates the erosion flux as a functionof excess bed shear stress and up to three empirical material coefficients. Some frequently usedapproaches, define excess bed shear stress as current induced bottom shear stress minus criticalshear stress below that no erosion occurs.
