摘要：

The model is applicable to open sandy coastal environents and consists of ten beach stages incorporating erosional and accretionary sequences of beach-surfzone morphodynamic conditions. Each stage is associated with a particular level of breaker wave power. Decreasing breaker wave power produces spatially controlled onshore bar migration, eventual bar welding, beach accretion and reflective surfzone conditions, increasing wave power generates beach erosion, dynamically controlled bar-channel formation and dissipative surfzone conditions. The effect of beach gradient is considered with regard to the influence on the degree of dissipativeness, edge wave length and cut-off modes, and standing wave length. -from Author
