Abstract
Ibusuki coast has attracted many tourists by its scenic and recreational value, however, recent progress of coastal erosion has resulted in frequent wave overtopping disaster. To avoid interruption of oceanic view by shore protection works, the integrated shore protection system composed of artificial nourishment works and increase of seawall crown height were adopted. DRIM (Distorted RIpple Mat) was also applied for the first time in Japan as a permanent facility to prevent the beach nourishment sand from being washed away. The present study discusses the efficiency of the countermeasure works comprised of DRIM and a groin based on wave observations and field surveys.
