A Study on the Shoreline Variations of Long Sandy Beach with Artificial Headlands

Headland is a coastal structure to control longshore sediment transport. This study focuses on the annual variations of shoreline configurations around three headlands established along a long sandy beach at Kashima coast, Ibaraki. With results of radar measurement, shoreline position, intertidal beach slope, and beach volumes are estimated by data analyses. Seasonal features of shoreline position are discussed in terms of seasonal wave conditions. Morphology around headlands and locations of breaker line are examined.
