heal.abstract In the present study a modified Boussinesq-type model is derived to account for propagation of regular and irregular waves in two horizontal dimensions. An improvement of the linear and nonlinear characteristics of the model is obtained by optimizing the coefficients of each term in the momentum equation, expanding in this way its applicability in very deep waters and thus overcoming a dominant short-coming of most likewise models. The values of the coefficients were obtained by an inverse method in such a way to satisfy exactly the dispersion relation in terms of both first and second order analyse. The modified model was applied to simulate the propagation of regular and irregular waves in one horizontal dimension, in a variety of bottom profiles, such as constant depth, mild slope, submerged obstacles. The simulations are compared with experimental data and analytical results, indicating very good agreement in most cases.
