The objective of the Phase I SBIR project was to demonstrate the feasibility of using Boussinesq type models to simulate time dependent three dimensional near shore ocean waves intended to be used as a military planning tool. The main issues are the accuracy and the domain of applicability of the model, and the adequacy of current computers to simulate these models for a sufficiently large domain. We used Nwogu's form of Boussinesq model or the Phase I work. Following Wei and Kirby, we developed codes to simulate one and two dimensional eguations. We tested the one dimensional code with an approximate analytical solitary wave solution and several monochromatic waves on flat or uniform slope bathymetry. We used the two-dimensional code to simulate one of the cases of the CERC elliptical shoal experiment of Vincent and Briggs. We compared the experimental and numerical time series at several gage locations with good agreement between the two. We also made some sample runs on field scale problems with uniform slope bathymetry. We analyzed the performance of the code on several computers. These results show the feasibility of this approach.
