This paper reviews the advancement in impacts of tidal dynamics on radial sand ridges (RSR), including its morphology, development time, formation mechanism, particle size distribution, material sources, sandbank evolution and stability of tidal inlet. Thousands of years ago, huge and radialized RSR was formed because sediment entered the radial tidal current field. Under the effect of tidal dynamics, fringe of RSR was eroded, center of RSR was deposited, and the tidal inlet tends to be stable. This paper proposes that the sediment module can be added in the tidal flow simulation, and long-term model can be applied to reproduce the whole process of formation and evolution of the RSR in order to compensate for many inadequacies of existing research.
