Abstract
Although the Katayamazu area in the south end of the Ishikawa Coast is located downstream of a longshore drift, its beach erosion is very intense and has frequently broken the coastal revetments. Therefore, the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) designated the area as its direct control area from June 2006. As the area located in the Etizen Kagakaigan quasi-national park and its offshore is a good fishing place and fixed netting fishery has vigorously grown, it is indispensable to consider its landscape and fishery when developing its beach erosion control works. This study determined the mechanisms of sediment transport in the area by constructing an artificial beach nourishment for test and implementing the monitoring field surveys of it. The study results will be used to develop beach nourishment works without longshore drift control in the area.
