ARC-SHAPED SAND DUNE TO PREVENT LOCAL BEACH EROSION AND ITS CONSTRUCTION METHOD

摘要

Disclosed is an arc-shaped sand structure that prevents local beach erosion and a construction method therefor. The arc-shaped sand structure and the construction method for preventing the local beach erosion of the present invention is to prevent the loss of the beach made of sand by reducing the blue energy, to the ground between the high and low coastal line, a predetermined height and It includes a sand hill formed by stacking in width, and the sand hill forms an arc opening toward the land surface so as to correspond to the incident direction of blue, or is arranged in a straight line or wave form parallel to the high or low coast line. do. According to the present invention, the blue energy is formed by being piled up at a predetermined height and width on the ground between the shoreline and the low-shore shoreline or between the high-shore shoreline and the low-shore shoreline to prevent sand from being lost by the blue energy and reducing the beach width. At the same time as it is reduced, it is possible to provide the effect of preventing beach erosion by supplying the lost sand to the sand of the dunes.
