Research on the Development of Wai-Shan-Ding Barrier, SW Coast of Taiwan, R.O.C.
Due to the abundant supply of sediment from the rivers, the west coast of Taiwan has shown a rapid accretion in history. As a result of this large areas could be reclaimed, such as the delta North of Putai — Wai-Shan-Ding sand barrier. In recent years, however, sediment supply is reduced due to river training and flood control. Consequently, the coastal area is now subject to erosion as the net sediment transport exceeds the supply to the beach. Therefore, shore protection is going to be cultivating the Australian pine tree by the Chia-Yi County Government.
Since the relatively well protected location of the area with regard to both waves and wind, no special navigational problems have to be envisaged. For the point view of whole development, it is easily planned the lee wind side of the delta as a marina, and wharf could be simply constructed as a floating type for sightseeing and cargo handling between this island to offshore island (such as P’eng-Hu or King-Meng, etc.). The main purpose of this marina is used for happy vacation time, such that the wharf is designed for the anchoring of yacht and hydro-foil cruiser, etc., the breakwater is need to constructed convenient to be fishing. Siwwing beach, beach park and some facilities for sightseeing are planned and designed in this offshore area for utility of the coastal management.
