Abstract
The bathymetric changes and changes in longshore sand transport passing through the tip of the headland were investigated using the contour-line-change model, while changing the shape and scale of the artificial headland. The maximum shoreline recession and eroded area downcoast of the headland, and rate of decrease in longshore sand transport were compared each other. It is concluded that the groin part of the headland must be extended first to reduce longshore sand transport off the artificial headland.
