ABSTRACTDeferent theories that have used in saltwater intrusion studies have reviewed in this thesis And the properties of Kashan plain as case study region have introduced Transmisivity ofcase study aquifer have estimated by R T map and pumpage tests results Groundwaterflow and its quality modeled by VISUAL MODFLOW model We study the variation ofchloride for control of groundwater quality 38 year 1964 2002 have been selected foraccuracy test of model Flow model by 1 4 meter and quality model by 52 milligram perlitter mean absolute of errors are reasonable and acceptable Then we predict the aquiferwater table and chloride concentration by this model under different scenarios in year2020 By running of model under present conditions the maximum of drawdown in 56 yearof model run is 78 meter There is a pipeline that is transport the water from Zayanderoodriver to Kashan model indicate that the backwater of Zayanderood water decriesdrawdown in center of plain to year 2020 Model indicate that the chloride of regiongroundwater at year 2020 under two above alternatives is very similar and in twoalternatives discharge wells that are near the saltwater region will have maximum impacton aquifer chloride change Next we study the hydraulic gradient of aquifer in cross sectionperpendicular the saltwater region Cross section indicates that the hydraulic gradient hasbeen inversed near the saltwater region By terminate discharge of wells near this region model indicate that the hydraulic gradient again will be inverse By moving the dischargeof these pumpage cells to upstream of plain also model indicate that the hydraulic gradientwill change to downstream of plain to 2020
