Abstract
Artificial headlands (HLs) have been constructed to reduce longshore sand transport. However, part of longshore sand transport could be transported downcoast turning around the tip of the HLs, because the tip depth is generally smaller than the depth of closure when HLs are constructed on exposed beaches. This often causes discrepancy between the previous explanation of the formation of a stable beach using the HLs and the reality of the eroded beach. Furthermore, the extension of the head part of the headlands at the final stage of the construction often causes beach erosion at the central part of the pocket beach surrounded by the HLs. These effect and limitations of the HLs were discussed.
