Abstract

Vulnerability assessment and vulnerability mapping, is an important strategy for management of karst WATER RESOURCES. Due to the geomorphology of developed karst in DALAHOO karst aquifers and in other natural conditions of the area, the spread of contamination in these karstic sources is rapid and extensive. Therefore, the purpose of this study was to provide a DALAHOO karstic aquifer vulnerability map in Kermanshah province against surface contamination using the COP model. According to the aforementioned approach, the COP method considers three factors to assess the resource vulnerability: Overlying layers (O), Concentration of flow (C) and Precipitation regime (P). After calculating three factors C, O, P and preparing their vulnerability map, these layers were multiplied and the final map of the vulnerability of the Dalaho karstic aquifer was calculated. The results show that 32.83%, 14.32%, 22.22%, 14.34% and 16.47% of the area are located in the very high, high, moderate, low and very low vulnerable zones and this classes have been 2222.88, 97.2, 147.49, 97.38 and 11.82 km2 of this area, respectively. Also, the results of vulnerability classes and their area indicate that 69.2% of the total area are located in the very high, high and moderate vulnerabilities, which indicates the high vulnerability of DALAHOO aquifer to contamination. The very high vulnerability zone with 222.88 Km2, has the largest area of the region.
