Reproducibility Evaluation of Pore Groundwater Based on Numerical Simulation in Taiyuan Basin
In order to evaluate the renewable ability of pore groundwater in Taiyuan basin,taking the pore aquifer in Taiyuan basin as the re-search object,based on the hydrogeological conditions of the study area,the groundwater flow numerical model was established and calibrated by using the MODFLOW module in GMS software.According to the simulation results,six evaluation indexes were calculated,including nat-ural recharge availability,regression recharge rate,regulation and storage coefficient,supplementary mining balance rate,groundwater resi-dence coefficient and hydraulic conductivity coefficient.The evaluation system of groundwater renewability was established and the renewabili-ty of groundwater resources in this area was analyzed.The results show that the overall flow characteristics of groundwater in the study area are from the northern part of the basin to the southern part,from the surrounding mountains to the plain area.The comprehensive evaluation index of groundwater renewability in each region of the study area ranges from 0.06 to 0.08,indicating that the renewable capacity of groundwater resources is weak.
