Abstract: Longshore currents are mainly generated by wave breaking, and defined as the nearshore current inside the surf zone, the importance of longshore current is its effects on initiation and transport of sediment. The convention methods of studying longshore current by physical experiment and empirical wave formulae were replaced by numerical model based on modified Boussinesq type wave equations to study the longshore currents and radiation sand group evolution of in coast of Jiangsu province. Directional spectrum wind wave was generated in pseudo three dimensional numerical wave basins to simulate the wave field with directional wind wave. Satellite map was used and compared with the numerical results. It is concluded the numerical model is of satisfactory accuracy and can be of engineering reference value in the design and planning of coastal structures and harbors.
