Abstract

Most commonly applied models for reference concentrations or sediment pickup rates do not account for wave breaking effects on sand resuspension. Consequently, they tend to underpredict the suspended sand load in the surf zone. Here, we present a new method to account for wave breaking turbulence effects in reference concentration models or pickup functions. An adapted reference concentration model is validated using recent laboratory measurements of near-bed turbulent kinetic energy and suspended sand concentration, yielding good agreement (r2= 0.60).
