Abstract

To determine the potential for groundwater contamination, Vulnerability should be evaluated in different areas susceptible to contamination should be investigated. Aquifer (carbonate) karst or part of it is karst aquifer in the western region of Iran; due to the natural conditions of the region and human activities, they are susceptible to contamination by carbonate aquifer through holes devourer and feeding point leading to pollution. The aim of this study was to analyze aquifer Vulnerability zoning map karst plain elster by using COP. This model uses three parameters including lining (O) the concentra flow(C) and precipitation regime (P) to assess the Vulnerability of groundwater against pollution GIS software. The results showed that the plain with an area 7. 8 km2 was dominated in terms of Vulnerability, being in the middle class. Other classes, respectively, were low with the area 18. 69 km2, high with the area 0. 65 km2 as part of the northeast plain, and much less with the area of 0. 6 km2, The results of the sensitivity analysis also showed that at the factorization (P) due to appropriate rainfall area, the maximum impact was in determining the Vulnerability of the area. And the factor (C) minimum has impact on determining the Vulnerability of the area. Due to the small size of the mature karst area, the wide extent of non-karst region was shown for the verification of results related to electrical conductivity data (EC) against discharge wells in the region with the high Vulnerability and moderate. A comparison was made too.
