基于Visusal ModFlow的苑庄水源地地下水位预测

摘要

根据苑庄水源地的水文地质条件，建立了水源地的水文地质概念模型。在此基础上，采用VisualModFlow对水源地地下水流场进行了数值模拟。误差统计分析表明，数值计算模型在识别与验证过程中的误差较小，模拟效果较为理想。根据所建立的数值模型，并按照设计开采量，对水源地运行后区域地下水位的变化趋势进行了预测。%　　AccordingtohydrogeologicalconditionsofYuanzhuangwatersources,hydrogeologicalconceptu-allmodelofwatersourcehasbeenestablished.Onthisbasis,byusingVisualModFlow,numericalsimu-lationofgroundwaterflowfieldinwatersourcesareahasbeencarriedout.Asshowedbyerrorstatistical analysis,numericalcalculationmodelhasthecharacteristicsofsmallerrorinidentificationandverification process,andhasgainedanidealeffect.Accordingtotheestablishednumericalmodel,andinaccordance withthedesignofextraction,thetrendofregionalgroundwaterlevelinthewatersourcehasbeenpredica-ted.
