Abstract: Alternate wetting and drying beachface induced by tide is one of the most important process influencing beach aeolian sediment transport. From the aspects of temporal and spatial variabilities of surface moisture content and cyclical variation of wind fetch length, as well as their own effect on beach aeolian sediment transport in the environment of alternate wetting and drying induced by tide, this paper summarizes the main progress and achievements of beach aeolian sediment transport influenced by tide. The main conclusions of this review are shown as:(1) The relationship between surface moisture variabilities and tidal oscillation is nonlinear, which is separated by a double hysteresis effect induced by watertable and capillary fringe; (2) A positive correlation between aeolian sediment transport threshold and surface moisture has been found in the case of surface moisture less than critical moisture threshold and the beach aeolian transport system will nearly shut down once surface moisture greater than critical moisture threshold; (3) The correlation between aeolian mass flux and fetch length can be divided into three stages according to the equilibrium state of sediment transport:positive before equilibrium state, negative after equilibrium state and irrelevant during equilibrium state. Finally, some necessary future research directions in China are put forward, according to the present research situation of beach aeolian sediment transport influenced by tide.
