Mud transport in sand beds provides a better understanding of the knowledge involving the environment and sludge-ization of tidal flats. In this study, the permeability reductions due to mud deposition under different flow rates, porosities and mud properties are investigated through laboratory experiments, and the validities of previous models are confirmed. The filtration coefficient of mud in sand beds was determined, and a new experimental formula is proposed to estimate the amounts of residual mud in sand beds. This formula can estimate the amount with a relative error of 10%. Further, the previous models of permeability reduction were found to be impossible to represent the experimental data, thus a new model is proposed. The new model can estimate the permeability reduction with a relative error of 10%.
