SEDIMENT TRANSPORT IN SWASH ZONE UNDER OBLIQUELY INCIDENT WAVES

Toshiyuki Asano

Abstract


Time dependent calculations on two-dimensional sediment transport are carried out. The swash wave front is treated as a moving boundary which can reproduce non-vanishing sediment transport rate even for landward region of the still water shoreline. Meanwhile, experimental investigations on this subject are conducted by florescent sand tracer method. By comparing the present and existing experimental results with the numerical ones, the sediment transport mechanism in the swash zone is discussed.

Keywords
