Abstract: A high-order staggered grid numerical model based on Nwogu's two-dimensional Bous-sinesq equations is developed in the thesis. The equations are solved numerically by using a fourth order accurate predictor-corrector method. This scheme has the conservative form for both mass and momentum. An internal wave generation method has been incorporated into the model. Sponge layers are placed in front of the open boundaries to absorb wave energy and minimize wave reflections. The model can be used to simulate the evolution of relatively short and weakly nonlinear waves in water of constant or variable depth. The performance of the numerical model is demonstrated by the comparisons against theoretical results, numerical results of previously published numerical model and experimental data. The agreements are very good. In particular, excellent results in terms of mass and energy conservation were obtained in the numerical experiment of water sloshing in confined containers.
