Analysis of mitigation effect of the open- and closed-type check dam
Debris flow caused by intense rainfall can damage facilities and endanger human life.

| description | Debris flow caused by intense rainfall can damage facilities and endanger human life. Accordingly, several models have been developed to predict and mitigate the debris flow damage, for which check-dam construction is essential. There are two types of check dams: open type and closed type. The former is suitable for granular debris flow containing little water, whereas the latter is suitable for water-laden debris flows. However, it is challenging to site the check dam to realize optimal mitigation effects. Therefore, we determined the best check dam location to reduce debris flow damage considering the two types. In this study, we simulated the Raemian apartment basin for the Mt. Umyeon landslides, which occurred in 2011. Constructing the open- and closed type dam at the upper side of the catchment produced the best performance. |
