The current debris flow warning model in Taiwan is established on the basis of the rainfall warning index. The study tries to establishes "the critical line of the occurrence of debris flow" by using the Soil Water Index (SWI) in the tank model which was used widely in Japan. The procedure of the study is as follows. The study estimates the suitable coefficient in the tank model in Taiwan and the estimating method and procedures of the peak discharge in the mountainous watersheds in Taiwan. The estimating result can be a reference for the mountainous watersheds with insufficient data. The study uses the SWI to calculate the critical line of the occurrence of debris flow in the current debris flow warning model in Taiwan. The critical line of the occurrence of debris flow can increase the accuracy of the debris flow warning and decrease the casualties in the debris flow disasters in the future. Furthermore, the study also establishes customized user extension software in Arcview System for further application.
