Abstract

Beach cusps are a series of arcuate scallops roughly uniformly spaced on beaches. They are inseparably related with nearshore current systems. Nearshore current systems form a variety of circulation patterns,which have been attracting many researchers'interest since a long time ago. In several theories proposed to explain the formation of nearshore current systems, Hino attributed their formation to the dynamic instability, and explained it in terms of linear stability analysis. In this study, his theory is revisited and improved in several aspects. The analysis proposed in this study successfully shows that beach cusps can be formed on beaches even when the wave crests are parallel to the shoreline.
