Effect of Ground Conditions and Mesh Size of Net-type Barrier on Debris Flow Behavior

Debris flow is a type of landslide that occurs mainly in mountain valley areas during heavy rainfall. Various types barriers have been installed South Korea to reduce the damage caused by debris flows. However, there no reasonable design standard when installing barrier, and an experimental study for performance evaluation insufficient. In this study, net-type barrier was evaluated analyzing effect ground conditions mesh size on behavior reducing front velocity deposition volume. As result, with less fine content, efficiency increased as decreased. Accordingly, significantly influence barrier. The can be sufficiently reduced through
