Abstract: A numerical model is presented to evaluate wave conditions in a marina basin for development and analysis of marina concepts. This model is based on the boundary integral equation method and is applicable to arbitrary-shape marina basins with perfectly or partially reflective perimeter walls. Diffraction of normal or oblique incident waves through the marina entrance is incorporated in the model. Predictions of the numerical model were compared to available analytical solutions and hydraulic model results for verification. Several alternative plans for development of the Monroe Harbor Marina have been analyzed. The numerical model was used to investigate the wave conditions in the marina entrance and berthing area with and without a proposed rubblemound breakwater. The study concluded that a rubblemound breakwater at the marina entrance is necessary to reduce the wave energy in the berthing area to an acceptable level.
