Sediments and Structures
Golden Beach in south Taiwan is widely known and has been attracting many beachgoers. In recent years, this beach has been eroded and measures to restore the sandy beach were required. The cause of the beach erosion was investigated on the basis of bathymetric survey data. In the study area, northward longshore sand transport, which was induced by the wave-sheltering effect of Anping Harbor, prevailed, and the rate of transport was estimated to be 1.25×105 m3/yr given the depth of closure of -6 m, the berm height of 2.2 m, and the characteristic height of beach changes of 9.2 m.
