Numerical Simulation of Groundwater Level Using MODFLOW Software (a Case Study: Narmab Watershed, Golestan Province)

To evaluate the effects of the current situation and future development on Source groundwater whether quantitative or qualitative point of view, simulation computer resources, a powerful tool in the optimal utilization of source is considered. Year recent several model of math and computer simulation of hydraulic behavior of underground water resources focus is located. Like making mathematical phenomenon hydraulic set of algebraic relations, differential and integral that the groundwater flow hydrodynamics and its relations with aquifer levels to show. In this study, like making Narmab aquifer located in Golestan province, using a mathematical model Visual Mudflow 3.1 was performed. Changes of water level data from 15 wells piezometer water table in the study area, were evaluated. Results with coefficient estimates 97 percent representation for all to month showed that the water level model with acceptable accuracy similar building and to model groundwater flow in the aquifer above the complex nature of her is. Predictedresults indicate that the probability of the next few years the water leveldrops in the aquifer, in the case of a large harvest process, will be verysevere
