Because of its abundance of land and water, Khouzestan has long been one of Iran's most productive agricultural provinces. Individual farmers have been effectively managing these resources to serve their short-term economic purposes. However, no long-range management plan has existed for groundwater. This thesis presents the results of a mathematical groundwater model developed for the ghale khawje plain in the Khouzestan province, employing conceptual groundwater modelling approach. For this purpose, Groundwater Modelling Software (GMS7.1) was used which supports the MODFLOW-2000 code. For modeling the Source/Sink Coverage,Recharge Coverage, Extraction Coverageand Soil Coverage were considered.The model was calibrated against the historical and observed water level data for period 2010 to 2011 in the non-steady state and verified for period 2011 to 2012. The results of applying this model to conditions in the study area provide a guide for managing groundwater resources in future. Selected water-management alternatives for the study area were evaluated with the aid of the ground-water flow.for coping with water shortage in the study area, feasibility of underground dam was assessed .After selecting the effecting parameters, they were surveyed in the plain by building associated layers and appropriated sites were determined by overlay method in GISenvironment. Then, based on simulation of groundwater model, the best place was selected.The proposed model was implemented for the conditions of drought and groundwater dam This study shows that underground dams may be a very useful instrument to substantially increase the available storageAnd reduce the negative balance in the ghale khawje plain aquifer..
