Abstract
In this study, we evaluated the erosion prevention effect of a vegetation sheet against surface water flowing down a slope. An erosion test was conducted in which water flowed on the surface of a slope where a vegetation sheet was installed. SfM (Structure from Motion) photogrammetry was adopted as a method for observing erosion scars. The test results confirm that the vegetation sheet has the effect of significantly reducing the amount of erosion and delaying the start of erosion, and clarify that the vegetation sheet spreads the surface water and reduces the flow velocity. In addition, the vegetation sheet promotes the infiltration of surface water into the soil, saturates the soil, and increases the amount of infiltration water discharged from the toe of the slope.
