Simulation of waves in near-shore zone for real time applications

This paper is dedicated to the simulation of waves in the near-shore zone (the zone where wave height is comparable with the depth). The method described allows simulating waves transformation and destruction phenomena. At the same time, it satisfies computer performance restrictions in real time applications. The method solves 2D problem and is based on boundary element method. To simplify calculations and increase performance, we use piecewise constant elements which does not have essential influence upon precision, as we modify the method properly. Results of this method - 2D profiles - can be easily used for imitation of 3D problem solution by interpolation between 2D profiles for different bathymetric charts. The paper contains the model description, drawings of wave profiles and 3D waves screenshots.
