Role of Geological Structures and Lithology in the Quantitative and Qualitative Changes of Eshtehard Aquifers

Eshtehard aquifers are Shoor River's catchment basin and water potential in different areas. Eshtehard aquifers, because of the diversity of geological formations and structures have different quality and quantity. This paper aims, to determine the relationship between quantitative and qualitative characteristics of water resources with the lithology and structural geological features of the area. In order to determine the scope of the area to survey and identify Eshtehard and distribution of geological formations and faults location using available geological maps ,then identify the wells and using the results of analysis of water samples from the map of the concentration of chlorine, sulfate, calcium, magnesium, etc. were traced. Interpretation of drawn map showed that the highest concentration of plains and the northern half of them changes, the mountains to the North and East of the center, which is consistent with passion Shoor River’s according to the results of water quality, northern plain the type and sodium chloride for drinking in the area of moderate to very unpleasant and harmful for agriculture in the category passion for agriculture are. As a result of salt in the northern of Plain along with the drop in water levels in the central of plain region have had a great impact on water quality.
