| The Application of Visual Modflow to the Simulation of Groundwater Nitrate Contamination in Shijiazhuang |
| Two-dimensional unconfined flow and nitrate transport models for a long period of 42 years in Shijiazhuang were built up by using Visual Modflow. A large number of groundwater monitoring reports and research reports were consulted so as to provide data for the models. Detailed water table and nitrate concentration monitoring data and historical water table contours were used to calibrate the models. Sensitivity analysis show that the areal nitrate recharge concentration seems to be the most sensitive factor causing the variation in nitrate concentrations of groundwater. The models calibrated were used to predict groundwater nitrate concentrations within the coming 30 years under three management schemes. The results of fitting, verification and prediction show that the models can serve as an effective tool for groundwater management in Shijiazhuang. |
