ABSTRACT

The rainfall factor is an important subject for a better understanding of landslide activity and is essential for developing warning system. The soil water index has been identified as one of the essential variable in sediment disaster such landslide and debis flow warning system. In this paper, we conducted the verifying of the soil water index, which was used for predicting the triggering time of sediment disaster in mountainous area. We investigated the adeption possibility of tank model for validation of soil water index. We calculated storage amount rainfall by tank model with rainfall data obtained from 2001 to 2009 in Jecheon Area. Using the tank model, the storage amounts in three tanks were calculated in time series and the second tank storage amount (S2) and total storage amount (TS) were applied in verifying. The high ranked S2 and TS showed good matching for the debris flow occurrence. These results show the possibility of prediction tool for the landslide occurring.
