Abstract

 The numerical models developed in previous our study are improved to simulate the influence of in- and exfiltration flow on swash sediment transport under the coarse grain condition. The interaction between runup wave transformation and seepage flow and the effect of in- and exfiltration flow on effective weight of coarse sand are considered in this models additionally. Through the comparison between present model results and previous experimental data, the influence of saturation in the beach slope becomes weaker according with increment of sand grain diameter. The characteristics of sediment transport under coarse grain condition can be evaluated by considering wave-induced infiltration-exfiltration flow.
