Wave Dissipation and Sediment Transport Patterns during Shoreface Nourishment towards Equilibrium

Implementing shoreface nourishment is an effective method to protect sandy beaches. A better understanding of the equilibrium mechanism nourishments necessary for coastal engineering designs and constructions. Two experiments on beach profile are carried out under mild wave conditions reflective intermediate beach. It observed that increases local height strengthens nonlinearity by its shallow water depth. The most intense breaking dissipation has been found crest nourishment, distribution energy rate more uniform quasi-equilibrium than initial profile. process-based numerical model used reproduce bed evolution successfully. On basis, it onshore bedload transport primary cause migration nourishment. magnitude decreases during towards equilibrium. sediment occurs over or in front shoreline, depending ’lee effect’ Furthermore, effects incident height, period, sea-level rise analyzed.
