碩士 === 國立中山大學 === 海洋環境及工程學系研究所 === 97 === This study is based on restoration of Kinmen coast fishing village of hydraulic model test of a comparative analysis of the planned project, as a result of long-term by Kinmen County coast north-east monsoon and the impact of ocean currents. In recent years, many coastal erosion and land damage case of loss. In order to avoid continued erosion, Kinmen county government since starting in 1990 for rebuild seawall to protect the coast. This paper is mainly due to a new erosion of lake waters near the fishing village, and a result of Economic Planning and Development Council''s request for a hydraulic model test and do the related planning and research. In order to achieve the purpose of beach erosion does not continue to be subject to planning. It can be found from previous research to study, the tidal effects of drift sand to the scene by investigate multi-based; and laboratories in order to describe the phenomenon of the different drift sand sharply degrees and to examine the different size. The purpose of this study is the tidal waves of the beach bed on the role, which will be part of tidal changes in water level simulation. Test results to a net drift of sand to make a comparative analysis of throughput and classified by Horikawa compared cross-section tank. The typhoon waves should be able to tell by the tidal waves but the bed is the rules of dramatic impacted. The monsoon is not much variance. In addition monsoon forecasting can be applied to multi-wave cross-section of the terrain slope changes. In addition it can be not exercised after the embankment of typhoon waves in Horikawa empirical section.
