Evaluation of karst development and karst water resource potential In drought conditions Using fuzzy logic model (FAHP) and analysis hierarchy process (AHP): a case study, Kohgiluyeh and Boyer-Ahmad Province, Southwest Iran

The main objective of this study is to prepare maps of karstification potential in the northwest of Kohgiluyeh and Boyer Ahmad provinces, southwest of Iran. The present study is elaborated in the broad area of the northwest of Kohgiluyeh and Boyer-Ahmad province, covering ۱۱۴۸ km۲. Geographic Information Systems (GIS) and Remote Sensing (RS) are used to create two maps depicting the development of karstification, consisting of five classes, showing the karstification potential and ranging from very high to very low. The extractions of these maps are based on the study of input data such as: lithology, lineament density, elevation, slope, rainfall, temperature, drainage density and vegetation cover. Weights are assigned to all these factors according to their relevance to karstification potential. Eventually, two maps based on weighted spatial modeling system are created. The verification results show that the fuzzy logic model outperformed the AHP model for the study area. .
