ABSTRACT

When wave energy builds up, beach berm and even dunes are quickly eroded with this material being removed offshore to form a bar parallel to the beach. It proceeds seawards during the course of the storm to reach some ultimate location prior to being dismantled and moved back to the beach by subsequent swell. There is difficulty in defining the steepness associated with storm, although it has commonly been accepted that steeper waves often produce a bar or a barred beach bar position and its crest height for a given storm condition. Therefore, criteria for the formation of bar and berm profiles respectively, need to be clarified. In this paper, the available experimental data of large wave tank (LWT) from U.S. Army Crops of Engineering and Japanese Central Research Institute of Electric Power Industry are used to construct a new relationship. Finally, criteria for bar and berm formation and seawalls design are found, and new criteria form are quite simple and widely applicable.
