Experimental Study on Improvement of Artificial Reef with Crests

Abstract

Wave flume tests and movable-bed experiments were carried out to improve wave dissipation effect of an artificial reef with crests and to reduce strong shoreward currents on the reef. Not only the effect of an ordinary-type artificial reef with crests but also that of a tandem-type artificial reef were investigated. It was found that the effect of an artificial reef with three crests was better than those of the other types in terms of the stabilization of the beach shoreward of the artificial reef.
