Abstract

Water is one of the most fundamentals demands of human society. Water consumption in industry, agriculture and household consumption, and also the lack of this source result in more extraction from groundwater sources. Irregular extraction from aquifers in dry condition of recent decades lead to significant drawdown in this sources. Recharging of the aquifer by injection wells is one of the solution for revival of the aquifers. The main purpose of this study is to investigate the effect of the injection well in recharging of the Unconfined aquifer by using meshless local Petrov-Galerkin. The approximation and weight functions are moving least squares and cubic spline functions respectively. The groundwater table in unsteady extraction mode simulated. The achieved results compared with finite difference, finite element and analytical method. Small amount of error of meshless method indicated the suitable accuracy of this method. Then the aquifer simulated in recharge mode. The height of water rise in the aquifer because of injection well, computed. Finally sensitivity analysis carry out on transmission coefficient, specific yield and rate of flow parameters. The height of water has more dependency to transmission coefficient and rate of flow than specific yield.
