摘要：

Debris flow generated by landslides due to intense rainfall can cause extensive damage to residential areas. To predict and prevent the severity of such damage, several numerical models have been developed. However, there are limited studies regarding the entrainment and erosion effect of debris flow. This research aims to analyze several erosion-entrainment models for the selection of erosion-entrainment models in debris-flow analysis. The study focuses on landslides that occurred in the Raemian and Sindonga apartment basins in Mt. Umyeon, Republic of Korea, on July 27, 2011. The impact area, entrainment volume, maximum velocity, inundated depth, and erosion shape resulting from the debris-flow modeling were compared with field data. The simulation results of each erosion-entrainment model were assessed through the receiver operating characteristic method.
