【Abstract】 From the viewpoint of dynamic analysis of interactions between currents and muddy beds, the mechanism of cohesive sediment suspension is investigated. The water layer is modeled as viscous fluid and the mud layer is modeled as visco-elastic fluid. Coupling the motion equation of water layer with that of mud layer, the critical velocity of suspension, celerity and wave length of interfacial waves are calculated. Comparing the theoretical results with the experimental results, some meaningful conclusions are brought out.更多还原
