Stability of hardly reshaping berm breakwaters has been investigated in this paper, mainly focusing on exposure to long waves. The study continues previous work by Aalborg University, which suggested that stability of berm breakwaters follow the plunging equation of the Van der Meer stability formula also in the surging domain. Different combinations of berm widths and elevations were tested in order to see if berm breakwaters in general follow the plunging formula or if they start to behave more like conventional breakwaters.
