【 摘 要 】

This paper is to investigate experimentally the beach erosion control function of a submerged tension-moored breakwater. Two- and three-dimensional laboratory experiments are performed. The single-peaked, double-peaked and triple-peaked cuspate spits are formed by placing the submerged tensionmoored breakwater on an accreted-type or intermediate-type beach. When the submerged tension-moored breakwater is placed on an eroded-type beach, the shoreline denudation is stopped and the shoreline is restored to the original location. The submerged tension-moored breakwater is concluded to be possibly one of effective measure works against beach erosion in an inner gulf area in which huge waves do not attack.
