Due to groundwater overextraction, during the recent years, Malekan plain aquifer has been faced to a risk of increasing salination. The groundwater flow model of the plain was designed, invesitagion of groundwater flow regime and precise hydraulic parameters estimation, utilizing the various method such as geological surveys, tomography methods, hydrochemical analysis and simulation of aquifer conceptual model in the GMS interface software package (GMS 10.1.4). The mass transport model was designed, then, to simulate the passways of salinity and dissolved solid concentration (Cl-) in the aquifer, using MT3DMS numerical code. The results show that the flow and transport model has explained the real behavior of the system with a good approximation and there is a good adaptation between the observed and simulated data. The over exploration of groundwater resources, which caused the water table decreasing,also resulted the extending of the saltwater intrusion in the northwestern part of the plain and thereby the deteriorating of groundwater quality and quantity in northwestern part.
