Abstract

Wave load and wave propagation over forelands S. Mai, N. von Lieberman Franzius-Institut for Hydraulic, Waterways and Coastal Engineering, University of Hannover, Germany Abstract Forelands are an important part of the coastal protection system at the German coast because they significantly reduce the wave load on the dike, i.e. on the main protection element. The effectiveness of forelands in wave damping was analysed using transmission coefficient for a site at the coast of Schleswick- Holstein, Germany, on the basis of field measurements, numerical modelling with SWAN and additional physical model tests in the large wave flume GWK of the University of Hannover, Germany. Besides of the influence the ratio of water depth and wave height the transmission coefficients strongly depend on the width of the foreland. With a width of more than 325 m the foreland provides maximum damping of the incoming wave field. 1 Introduction The German coastal system comprises a series of protection ele
