Wave Transmission at Detached Breakwaters for Shoreline Response Modeling

Abstract : The Coastal and Hydraulics Engineering Technical Note (CHETN) herein evaluates selected available formulas for predicting wave transmission at reef breakwaters and more conventional multilayer structures, leading to recommendations for the most appropriate formulas for shoreline-response modeling. The GENESIS shoreline response numerical model is modified to allow for automated time-dependent calculation of the wave transmission coefficient, and a case study is presented to illustrate the new predictive capability.
