It is important to predict occurring place and time of debris flow by the way of researching rainfall and morphological data. This study was carried out on the basis of investigation of hazard literature and inquiry of them to the competent firehouse, etc. Forecast model of debris flow's occurrence was created by the method of multiple discriminant analysis of geographical and rainfall factors. This model could give an effective warning and evacuation line for every debris flow with occurring potential in hazardous torrents. As a result of this research, it was shown that the precision of the predict of debris flow's occurrence by this method was higher than the standard one by only rainfall factor.
