Docks and Harbor Engineering When a wave strikes a vertical breakwater in deep water, it is reflected back and on meeting another advancing wave of similar amplitude merges and rises vertically in a wall of water. This phenomenon is called Swell Clapotis Fetch Surf Swell Clapotis Fetch Surf ANSWER DOWNLOAD EXAMIANS APP
