Abstract
The numerical simulation of the surf zone in very shallow water particularly requires a proper reproduction of the topography in the model. The information about bottom elevation comes from diverse measurement methods with different accuracies. To complete the topographical information, a simple method to generate additional points considering the shape of groynes will be presented. The keynote of this paper is a novel procedure to generate an equidistant rectangular calculation grid. This method is based on b-spline surfaces which approximate the topography. Results for numerical wave simulations are used to compare this novel meshing method with the classical way of generating element grids.
