Abstract
A wave propagation model for linear periodic waves in a coastal sea region is developed. The model includes refraction and diffraction of gravity waves on water over arbitrary bathymetry. Energy dissipation in the form of wave breaking and turbulent bottom friction is modeled. The authors discuss the use of the computer model in simulating waves nearshore in the absence of any current. The method of solution involves complex potential theory. This complex potential can be decomposed in two ways: (a) real and imaginary parts and (b) amplitude and phase. The authors compare solutions from both techniques, regarding such issues as mesh resolutions, storage requirements, and computation times.
