Simulation and Preparation Mathematical Water Budget Evan Plain ‎Groundwater Using MODFLOW and GIS in GMS6.5 Environment and ‎Comparison It with the Manual Budget

ABSTRACT: One of the appropriate management ways to understand and manage the countryʹs water resources, which are largely dependent on groundwater, is the use of mathematical models of numerical and results of the water budget model. Models of Groundwater simulation nowadays play crucial role in the development and use of policies of groundwater. In this study, to obtain water budgets have been considered the‎‏ using mathematical optimization techniques. This technique is based on the simulation ‎ data of finite difference model of the Evan plain and evaluates its results using unit hydrograph and comparison it with manually budget the aquifer. The comparison this two budget shows that the mathematical model to optimize of the data and define the different zones of hydrogeological have a high power in the aquifer simulation and provides a better data.
