Abstract

This study tried to comprehend the generation mechanism of the rip current at the enclosed beach by the groins. Firstly, this study did field survey and comprehended the large scale and velocity of the rip current. In this method, the rip current was pigmented by the sea water colorant, and the pigmented current was recorded as the aerial photograph by the multi-copter. Secondly, this study simulated the rip current in accordance with the results of field survey, and the results of simulation and filed survey ware compared.
