Shoreline change in sandy beaches formed between two
headlandsto the wave actions was investigated in this reserch
by meansodel tests. The shoreline between the headlands was
firstlyed from an initially straight line to an equilibrium
shorelinehe model experiment then was received the wave action
which ishigh wave energe. It was found that equilibrum
shoreline wasually destroyed. Typical sand bar was also found
in the bottomr this situation. However, both the equilibrum
profile andeline will soon be reconstructed when the original
low energyaction again. The result implies that the headland
control isicable in defence of the coastal erosion.
