| Abstract | The constructions of 700m Songkhla jetty and Songkhla Deep-sea Po1t cause the dramatic shoreline morphology, large amount of accretion at the updrift side and erosion at the downdrift of Songkhla Jetty. The Meditation Center is considered as an essential public area which confronting severe coastal erosion. The present remedial measure, sand-bag/small stone groin is ineffective and can not fully protect eroding area. So more effective remedial measure is urgently desired. In order to control beach erosion nearby Songkhla Deep-sea Port, it is necessary to search for the most suitable remedial measures. Various feasible shore protective measures both by construction of coastal structures and non-coastal structures are analyzed as remedial measures. The preliminary design for project life of 50 years of rubble mound groin, offshore breakwater, detached breakwater and rubble mound seawall are performed. Sand bypassing is select as non-coastal structure method. In this site condition, sand bypassing can be conducted by the use of truck and boat. The considering parameters are composed of economic consideration, construction technique, construction material, functional purpose, environmental impact, and aesthetic view. From this investigation, based on multicriteria decision method it is found that construction of rubble mound groin is the best alternative to remedy beach erosion at the Meditation Center. Economic analysis is introduced to show reliability of proposed project. The estimated construction and maintenance cost of rubble mound groin is 1,900,000 Baht. Benefit/Cost ratio based on discounting rate of 5 per cent is 6.0 which strongly confirm longterm profitable of project. |
