Abstract

Suspended sediment flux and cross-shore beach deformation in the breaker zone are elucidated experimentally with the CRIEPI's irregular wave flumes of large and middle sizes. Effects of long waves on suspended sediment transport are also investigated with a new experimental system for correct reproduction of infragravity waves bounded by irregular wave groups. Based on the experimental results, the pick up rate from sea bed and convection and diffusion of suspended sediment are modelled, and a new numerical model is developed for cross-shore beach deformation due to irregular waves. This numerical model can well reproduce wave deformation, suspended concentration, undertow, sediment flux and beach topography change.
