Numerical model for solving Bousiinesq-type equations: comparison and validation

In order to solve the Boussinesq-type equations developed by Zou[1997, Science in China, 27(5), 460-473], two finite methods were used:a predictor-corrector scheme and an ADI algorithm.The comparicons of the matterical results of the two methods were through a breakwater gap and the wave refraction over made for a variety of cases, including the wave diffraction the bathymetry with a deep channel.Comparisons were also made between the mathematical model results and those from physical model in order to validate the two methods.The differences in computational efficiency and accuracy of the two methods were discussed.
