台灣多數山坡地往往因地質較為破碎及高降雨強度之降雨事件影響進而發生土壤侵蝕、堆積等土壤顆粒搬運行為，民生生活也多受其影響。因此如何評估降雨引致土壤顆粒搬運過程中之土壤沖蝕量成為研究重點，其中本研究對於降雨產生地表逕流使非飽和邊坡表層土壤沖蝕搬運之力學機制進行深入探討.研究場址位於曾文水庫旁之東西坑溪集水區大埔鄉嘉149線0.5K叉路旁一處邊坡，進行長期非接觸式表層土壤距離量測，採用邊坡沖蝕即時監測系統進行降雨量、地表分層含水量及土壤表層距離等量測，且藉由現地降雨量量測及土壤表層距離量測結合無限邊坡破壞理論進而探討現地有效降雨事件中邊坡表層土壤搬運之力學機制。

Most hillsides in Taiwan are often affected by erosion and accumulation of soil particle transport behavior due to weak geology and high rainfall intensity. Moreover, people's livelihoods are also affected by soil particle transport behavior. Therefore, how to evaluate the amount of soil erosion during the movement of soil particles caused by rainfall has become the focus of research. In this study, the mechanical mechanism of surface soil transport and erosion of unsaturated slopes caused by rainfall and surface runoff is deeply discussed. The research site is a slope at Chiayi County Dapu Township county road 149 0.5K. This area is in the water catchment area of Dongxikeng river next to Zengwen Reservoir. Then. The study uses a slope erosion real-time monitoring system to measure rainfall, surface water content and soil surface distance for long-term non-contact measurement of surface soil distance. In addition, after combining infinite slope failure theory ,rainfall and surface distance measurement, the mechanical mechanism of surface soil movement in the field of effective rainfall events is discussed.
