EFFECT OF SHOREFACE NOURISHMENT FROM OFFRSHORE BAR ON THE RECOVERY OF SHORELINE

Abstract

 In this paper, a new method of beach nourishment, in which sediment dredged from a longshore bar is filled at the shoreface, was proposed as one of the measures for beaches that suffer from chronic beach erosion after a storm. Laboratory experiments showed that the proposed method effectively accelerates the recovery of the shoreline and formation of the berm. Among the parameters that may influence the effectiveness of the method, a volume of nourishment, characteristics of the recovery waves, and water level were important. The location of deposition was not very sensitive.
