Abstract

This paper presents the study of coastal topography changes and observes the situation with surf wave motion influenced by CKPB. CKPB is set some different experimental conditions, including location, spacing, row count to test. The CKPB made from nets is permeable structure. The wave will happen breaking when the wave passes through CKPB and wave energy is decreased. The sand wave in sea bed is changed from off-shore to inshore by CKPB. The changes are sand ripples, primary bar, primary pit, secondary pit and final bar. The spacing (d) of CKPB is the main factor for test in this paper .
The best condition from test results is 0d for a single row and is 1d for double row. Overall, the optimal spacing of 0.5d, will contribute to the final deposition mound siltation.
