A new set of Boussinesq type equations is used in this paper to numerically simulate the shoaling of surface waves from deep to shallow water. The new equations, derived by Nwogu, one of the authors, are able to model larger coastal areas because of its improved linear dispersion characteristics. Numerical results are presented for the shoaling of solitary, regular and irregular waves. Comparisons are also made with field data obtained from the Hazaki Oceanographical Research Facility (HORF).
　The results demonstrate that the new Boussinesq model is a practical tool for simulating the nonlinear shoaling of ocean waves from deep to shallow water.
