The numerical model documented here, RCPWAVE, can be used to solve wave 

 propagation problems over arbitrary bathymetry. The governing equations 

 solved in the model are the "mild slope" equation for linear, monochromatic 

 waves, and the equation specifying irrotationality of the wave phase function 

 gradient. Finite difference approximations of these equations are solved to 

 predict wave propagation outside the surf zone. Inside the breaker zone, an
