Abstract
On the Shonan coast, the reduction of a river mouth terrace offshore of the Sagami River and the shoreline recession downcoast of an artificial headland and Chigasaki fishing port breakwater have occurred owing to the imbalance in sand budget, causing several unsolved issues. In this study, these issues were studied, while refering the results of the the previous studies by the analysis of the shoreline changes on the basis of the aerial photographs and NMB data collected since 1999. The beach changes on the entire Shonan coast were triggered by the decrease in eastward longshore sand transport, even though beach nourishment has been carried out. Sand bypassing and recycle use of sand is required.
