AbstractAssessment of debris flow hazards is important for developing measures to mitigate the loss of life and property and to minimize environmental damage. Two modified uncertainty models; Set Pair Analysis (SPA) and modified Set Pair Analysis (mSPA); were suggested to assess the regional debris flow hazard. A case study was conducted in seven towns of the Beichuan county; Sichuan Province; China; to test and compare the application of these two models in debris flow hazard assessment. The results showed that mSPA only can fit for value-variables; but not for non value-variable assessment indexes; Furthermore; as for a given assessment index xi; mSPA only considers two cases; namely; when grade value increases with xi and when grade value decreases with xi. Thus; mSPA can not be used for debris flow hazard assessment but SPA is credible for the assessment because there are no limitations when using SPA model to assess the debris flow hazard. Therefore; in this study SPA is proposed for assessing debris flow hazard.
