Flooding is one of the known natural disasters which a lot of financial and living losses associated with it.This phenomenon with the help of identification of flooding areas and proper management can be controlled.The purpose of this article is evaluationand zoning of the risk of flooding in the basin of Zangmar inMaku City using fuzzy model. For this reason, layers of information related to the slope, height, planimetriccurvature, profile curvature, land use, soil, geology, distance from the river, drainage density, and NDVI gnomonare used. Flood zoning map using Gamma Operator 5/0, 7/0 and 9.0 were prepared and to test the efficiency of fuzzy model and choosing the appropriate Gamma Operator, correlation of parameters were calculated separately with each of the operators.The results showed that Gamma 9.0 is the most appropriate operator. At final zonation maps, the risk of flooding areas lies in upstream and north basin. Most of areas with very high risk of flooding are located in convex slopes, crest and slopes between 0-7 percent of the most mountainous regions. The height of these levels are often between 800-1200 meters.
