NUMERICAL MODEL FOR LONGSHORE CURRENT DISTRIBUTION ON A BAR-TROUGH BEACH

Yoshiaki Kuriyama

Abstract


A numerical model for the time-averaged nearshore current in the surf zone is developed to simulate the longshore current distribution on a bar-trough beach that has a peak velocity shoreward of the bar crest. Momentum fluxes due to mass transport under broken waves, which are ignored in other models, are included in the present model. The validity of the model is verified with field data.
