Karst development zoning to identify karst water resources using Fuzzy logic model and AHP (Takab Basin)

Regarding the role and importance of water resources in supplying water resources and location of settlements, one of the tasks that are carried out in karst areas is the zoning and influence of factors affecting the development of karst areas. Accordingly, in the present study, the factors affecting the development of Karst and the zoning of this development in the Takab Basin (Sarouq) And the aim is to identify areas susceptible to Karst development with a geomorphological view. For this zoning, eight parameters of geology, rainfall, river, fault, slope, direction of gradient, elevation amplitude and temperature have been used. Accordingly, in this research, two methods of fuzzy gamma and AHP for zoning of karst in The studied basin has been used. According to this objective, in this research, two methods of fuzzy gamma and AHP for zoning of karst in the studied basin have been used and the results show that finally, by comparing these two methods in terms of the highest accuracy and The accuracy of the map with field observations, the final map of the hierarchical analysis method (AHP), is most consistent with reality in the region. So that the highly developed, developed and middle class has more than half the area of the basin and is geographically located in the southern and central parts of the basin, which are Choploo, Qoche, and Dorbash and district Takhtsoliman and the city of Takab includes.
