When landslides and debris flows occur, predicting sediment discharge is important for soil erosion control. In this study, aerial photography and GIS spatial analysis were carried out on a landslide and debris flow area. The sediment discharge was most affected by the flow length, flow width, and the amount of slope failure within the source area. In particular, the sediment discharge was highly correlated with the flow length. We have developed an equation that can estimate sediment discharge. The developed equations are grouped and four estimation equations are proposed. The developed sediment discharge equation can predict the amount of soil runoff downstream when a landslide and debris flow occur in a forest watershed. In addition, it can be used to make design decisions concerning the scale and location of erosion control dams, contributing to disaster prevention in downstream areas.
