Abstract: This paper identifies tools that are being utilized to determine the most environmentally beneficial location for a nearshore berm to be constructed at Breton Island, Louisiana. The computer model STWAVE is being used to examine the wave field resulting from construction of various submerged berm configurations. A series of seabed drifter deployments is also being conducted to track the bottom currents which could provide information on likely directions of sediment movement. By studying the results of these two technologies, better berm siting guidance can be provided to maximize wave attenuation benefits and predict the fate of the material placed in a berm.
