Abstract

In order to investigate the influence of water depth on the profile of reshaping breakwaters, model tests have been performed in deep, intermediate and shallow water conditions. The results show that the reduction factor for the dimensions of a reshaped profile in intermediate and shallow water conditions does not depend only on the wave height reduction. Other influencing factors are identified as breaking depth, wave steepness and foreshore slope. Moreover, at any water depth condition, the characteristic wave height corresponding to the frequency of stone movements on a reshaped profile is larger than the significant wave height. In the present tests, good results are obtained using the 1/50 wave height. Finally, whereas the offshore evaluated reflection coefficient increases with the water depth at the structure, the same coefficient evaluated in front of the structure shows an opposite trend.
