EXPERIMENTAL STUDY ON BORE-INDUCED SWASH INTERACTIONS

Botao Chen, Gustaaf Kikkert

Abstract


The current study reports the results from a new laboratory experimental investigation, carried out to improve understanding and modeling of the internal kinematics of swash interactions, and its role on beach face morphology. Two typical types of swash interactions, wave capture interaction and backwash interaction (Erikson et al., 2005), were observed in detail by conducting large-scale dam-break experiments in a flume with two adjacent reservoirs and a fixed coarse-sand beach. The experiments were designed to enable detailed measurements of swash depths, velocity fields and turbulent quantities at different locations across the swash zone to be obtained.
