Abstract

Saltwater intrusion is in the bottom of aquifer with gradually horizontal and vertical moving shortcoming of the most important quality issue especially in desert area. In this study the 3-D simulation of saltwater intrusion carried out by MODFLOW, MT3D and SEAWAT models. The results of flow modelling show that the decreasing in water table has been continued, in order to the hydraulic gradient in bottom of aquifer is reversed. . Considering the trend of groundwater direction indicated a huge volume of saltwater with high concentration moved to the aquifer. For 3-D simulation of quality flow MT3D model have been used. The results of this study show that the chloride concentration considerably increased due to 7000 ppm in the bottom of aquifer. Moreover, the saltwater intrusion moved about 100 meters to the aquifer in interface area. Consequently, the prediction of saltwater intrusion reach to 400 meters in near future.
