Review on Water-sediment Movement in Swash Zone

Abstract:

In this paper， the basic characteristics of water-sediment movement in swash zone are described， and the latest research progress on the influence of infiltration or exfiltration， bore turbulence， sediment advection， settling or scour lag， longshore current， wave-swash interaction and wave group on the water-sediment movement in the swash zone is summerized. The basic facilities of physical experiments on the water-sediment movement in the swash zone are introduced， and the latest progress of the observation technology of the sediment movement in the swash zone is reviewed. Two types of numerical models used to study the water-sediment movement in the swash zone are presented， and their advantages and disadvantages are investigated. The limitations of existing research methods and results are discussed， and the future research prospects are proposed.
