Short summary
Debris flow early warning has always been based on well-calibrated rainfall thresholds. For areas where historical data are insufficient, to determine a rainfall threshold, it is necessary to develop a method to obtain the threshold by using limited data. A quantitative method, a new way to calculate the rainfall threshold, is developed in this study, which combines the initiation mechanism of hydraulic-driven debris flow with the runoff yield and concentration laws of the watershed.
