Abstract
Sub-basin prioritization and morphometric characterization analysis is one of the efficient and low-cost tools in identifying flood hazards. The purpose of this study is to Prioritize the flood potential of watershed sub-basins using morphometric parameters, combines of model statistical correlation and multi-criteria decision making systems. 17 morphometric parameters including slope, elevation, curvature, Ruggedness number, elongation coefficient, circularity coefficient, equivalent rectangle, drainage density, Stream Length, coefficient Permeability, concentration time, duration-intensity of precipitation, land cover, land use, geology, Bifurcation Raito, Length of overland flow were studied. the relationship between parameters and weighting results showed that in AHP in climate and Morphotopography (slope, height, curvature, number of roughness) was one of the important factors of flooding. In ANP method, slope and concentration time (0.11) duration-intensity of rainfall (0.12) has become one of the most important factors in flooding. Ranking in AHP method showed that the sub-basins of Imamzadeh Davood, Taloon and Doab to Respectively with the highest score (0.74, 0.50, 0.38) and in the ANP method with the highest score (0.97, 0.51, 0.48) in the sub-basins of Imamzadeh Davood, Talun and Sangan They are located in the first to third places and the intensity of flooding in them is higher than other sub-basins. According to the results, relationship between the equivalent rectangle (width) and the circularity showed a strong correlation between these two variables.
