Abstract

This study proposes a sediment-budget model to predict the temporal variation of debris volume stored in a debris-flow prone watershed. The AA. acquire a dataset of 44 potential debris-flow torrents (PDFTs) from the Tungshih area of central western Taiwan, where many shallow landslides and debris flows were triggered by the 1999 Chi-Chi earthquake and subsequent typhoons. This dataset is utilized to derive and to validate the susceptibility model. A susceptibility index, which reflects the possibility of debris flow occurrence in a PDFT, is then calculated based on the proposed susceptibility model
