Detection of Ground Water Changes Using Geographic Information System (A Case Study; Arak Plain, Iran)

K. Solaimani and S. Sadeghi    

Abstract: The aim of this study is to investigate the detection using hydrometric data and GIS technique for the central part of Iran because of the water shortage for agricultural and industrial activities. In many parts of Iran, the pressure of agricultural development is causing a surface-water scarcity. That means groundwater resources recharge will be effected for this reason which caused a major problems in future. The study area of Mayghan is located in Central Iran with 2854.63 km2 as a part of Arak plain and near to 110 km2 as a playa. Before 1951, there was no evidence of deep well in this area and the related activities were depended on the low stream rivers, aqueducts and wells. According to the hydrometric records of the regional water organization 3161 wells added to the injection wells, between 1970 and 2004. The qualitative increasing of these wells can be calculated as annually growth of 94 for the study area which are totally pumping about 531.5/million/m3 with annual increasing of 15.63/million/m3. The growth of annual demands for water supply has caused some environmental problems since there was no sufficient water intrusion to the aquifer plain which causes constantly the height of ground water reservoir declination as shown in related graphs. In this study, groundwater data were analysed using ArcGIS, statistical methods, geographic information techniques of Arc view and Ilwis.
