LABORATORY REPRODUCTION OF SEABED SCOUR IN FRONT OF BREAKWATERS

Isao Irie, Kazuo Nadaoka

Abstract


Mechanism of scour in front of breakwaters by standing waves in two and three dimensions has been studied theoretically and experimentally to clarify the experimental conditions by which the prototype behavior could be best reproduced in laboratory. The phenomenal reproduction of scour in laboratory is satisfactory if some conditions on the characteristics of waves and bed materials are fulfilled. This enables experimental approach to find out the optimum protection methods against scour in front of breakwaters.
