The majority of soil (known as effective sediment) that flows into the ocean originates from rivers. However, if the movement of soil within the sedimentary system is interrupted by activities such as excavation or construction, the balance of sediment in the coastal area will eventually collapse, leading to accelerated coastal erosion. Therefore, in areas where soil is supplied from rivers, it is important to evaluate effective sedimentation along with coastal sedimentation. This requires a quantitative evaluation system that takes into account the mountainous topography of Korea. The aim of this study is to improve the predictive performance of the change in alignment by evaluating the effective sediment, taking into account the amount of artificial runoff soil. In the absence of quantitative evaluation data on the amount of artificial soil runoff resulting from the development of mountainous areas within a sedimentary system, the amount of runoff was evaluated through satellite imagery. As a result, the predictive performance of line change according to the effective sediment was significantly improved.
