Among geophysical techniques, the electrical methods, especially geoelectric, are the best and most suitable methods for investigation of groundwater and layering. For the purpose, ۳۰ geoelectrical sounding in the ۶ profile north-south were done for the study area and obtained data were interpreted by two methods: quantitative and qualitative. The quantitative interpretation was made by the mannual method and computer method by the use of IPI and VES softwares. Then for studying and groundwater in the studied area the values of espatial electrical resistivity in the electrical sounding and in the per profile drawing cross section geology were used to these cross section recognized geology layers.Interprttation results indicates a layer limestone under the gravel and sand layer.The layer is thin, approximately ۵-۲۵ meters; According to studies profiles. Karstification in this layer came to show the exsistance of groundwater in fewer ves points. Low thickness of this layer makes the drillig water supply uneconomical.
