STUDY ON SCOURING AT THE FOOT OF COASTAL STRUCTURES

Shoji Sato, Norio Tanaka, Isao Irie

Abstract


This paper presents the results of two-dimensional model experiments conducted in order to clarify the basic characteristics and to find out some preventive measures against scouring around coastal structures. The applicability of these results to the field are discussed on the basis of some results of field investigations. The results of two-dimensional experiments presented herein show that the characteristics of waves just in front of structures and their reflection by structures are most important factors of scouring. The results of field investigations, however, indicate that in addition to those two factors, the currents caused due to waves around structures play important roles m scouring.
