The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics in breakwaters, and at historical breakwaters designers have been able to develop a configuration that uses smaller stones than conventional design approaches. The cost savings are thus very significant over conventional design. This paper examines a berm breakwater under construction in the Bering Sea in the most severe wave environment a berm breakwater has yet been built.
