Fundamental issues in Japan’s management system of coast for preventing beach erosion

چکیده

When an offshore or port breakwater is constructed on a coast, beach erosion often occurs nearby beaches of the due to wave diffraction effect associated with formation wave-shelter zone, because longshore sand transport triggered from outside inside zone. Similarly, when unidirectional blocked by breakwater, will occur downcoast. In these cases, movement key factor. Another aspect arisen management system land near coast subject such movement. Japan, coastal under jurisdiction several agencies. transported alongshore across 2 areas, right belongs agency administrating area which deposited, and originated has no right. Thus, this leads uncoordinated solution problems, can freely move boundaries areas. study, issues were studied through real examples. Even though accuracy predictive model changes increased, implementing fundamental condition difficult issue unsolved as it is.
