MATHEMATICAL MODELLING OF WAVE OVERTOPPING AT COMPLEX STRUCTURES: VALIDATION AND COMPARISON

Abstract

A validation study for a mathematical model called OTT-1d from HR-Wallingford modified by the Coastal research Station is presented in this paper. The model is based on the one-dimensional nonlinear shallow water equations (NLSWE) on a sloping bed describing the horizontal mass and momentum balance. Demonstrating for several wave flume test data OTT-1d can be verified as a reliable tool for predicting the mean overtopping discharge at simple an complex geometries. Furthermore a comparison of the modelling results to actual used calculation methods is done to show the limits of each calculation methods relating to the complexity of the structure.
