[email protected] Abstract—The present research uses a simple and direct response. Raaijmakers et al. [2] also applied multi- method to assess the hazard rating of potential debris flows objective evaluation to examine flood risk perception and in Changhua County of Taiwan based on field investigation mitigation, and Boamah et al. [3] used Generalized and numerical simulation. Taking 7 potential debris flow Linear Models (GLM) to examine how personality areas in Changhua County as the research objects, linear combination is utilized to evaluate the hazard rating of disposition, social network, and socio-demographic debris flow disaster in disaster-prone areas. In addition, factors mitigate the complex relationship between Analytic Hierarchy Process (AHP) is applied to design the stressful life experiences of floods and the adoption of expert questionnaire for determining the factor weight, and coping strategies among communities in Nigeria and pair-wise comparison is used to calculate the eigenvector as Tanzania. As for debris flow disasters, a multi-criterion the weights of criteria. The calculated weights are further decision analysis method and fuzzy synthetic evaluation used for the hazard assessment.
