Title: Numerical simulation for present a relationship for optimize exploitation groundwater (case study: Damaneh aquifer)
Abstract: In this study, an Analytical program has been conducted to identify the behavior of of amplitude aquifer to different water turbulence and find a relationship for optimal groundwater abstraction of this aquifer. The geographic information system is first used to process geological, hydrological, and hydrogeological data, and then the MODFLOW-2000 code is used to simulate the flow. After the initial simulation, the hydraulic conductivity parameter in a stabilized steady situation (April 2005) and in a unstable situation (2004-2005) The hydraulic conductivity parameter and the discharge coefficient, in particular, were measured. Then, for a period of 18 months, with the data of 2012-2013 and for the optimized parameters, the validation test was performed. Two different management scenarios for a 102-month period were defined to predict groundwater level fluctuations and the effect of water pumping from the domain aquifer. The results of the numerical model analysis show that if the aquifer is operate with the current situation, the sharp drop in water in the aquifer and the gradual drying of the aquifer will continue in the future, so that the maximum and minimum drop limit of observation wells number 5 und 3 is respectively 12/20 meters and 1.70 meters. Of course, lowering the discharge pumping rate will improve this situation. Therefore, considering that the range amplifier is fully developed, the power supply-pumping diagram was drawn. The results show that by using the nutrition-pumping diagram, the water level can be controlled to a certain extent by considering economic and environmental issues and the areas of aquifer that are close to the aquifer (trava boundaries) are affected and the wells operating in this area have the least effect on the drop in water level.
