The Cheleh basin is located in the south of Kermanshah province and the Zagros morphotectonic zone. According to the vast of limestone formation, and the presence of tectonic faults, developed karst land forms has evolved. The purpose of this study is to survey the development of karst and the effect of permeable factors on it. Main data of the research are formed by topographic and geologic maps and aerial photos along with hydrology stats of Department Energy. In this study are nine environmental factors as independent variables and Geomorphological karstic landforms as the dependent variable were examined. At first was identified quantitative and qualitative criteria and then doing field works, interviews and questionnaires, these criteria and factors are analyzed using Analytical Hierarchy Process and finally were gained in GIS, maps and unificating and Final correction with the help of fuzzy logic, respectively. In order to better conclusions, the region in terms of development in karst was divided into four sections. Combining data layers approve the effective role of lithology (Asmari Formation) in the process of development in karsting. Also has seen development in karst on the southern highlands of basin and flat lands at the head of the northern anticline and along the main fault of the region. karst areas Developed 107.95 square kilometers about 22.5 percent and regions with average development of karst covers 34 percent of the watershed basin.
