The reduction of wave overtopping by means of rubble mound revetment (at the Dawlish coastline)

To evaluate the performance of an additional rubble mound breakwater to the Dawlish Coastline sea wall defence, a number of 2-dimensional physical model tests were undertaken at the Plymouth University Coast Laboratory. The subsequent results of the tests are presented and analysed in this paper. The research found that the most significant influencing factors on overtopping were the significant wave height and the crest freeboard.
