A numerical model is developed for the simulation of wave transformations and wave induced nearshore current, that is applicable to irregular bottom topographies. Combined model has two components, a wave propagation model and a wave driven current model. Wave propagation model is based on extended mild slope equation and could simulate wave shoaling, refraction, diffraction and breaking. Linear, harmonic, and irrotational waves are considered. To describe the wave motion, mild slope equation has been decomposed into three equations that are solved in terms of wave height, wave approach angle and wave phase function. Model does not have the limitation that one coordinate should follow the dominant wave direction. Different wave approach angles can be investigated on the same computational grid. Wave driven current model is based on vertically averaged non-linear shallow water equations. In the solution method, partial differential equations are replaced by a set of finite difference equations on a space staggered grid. Model has been applied to Obakoy coastline that is located at the Mediterranean Sea coast of Turkey.
