摘要
首先建立了汾河二库及其下游地区水文地质概念模型,然后根据地下水水头长观资料识别模型的水文地质参数,运用可视化标准软件Visual Modflow,建立了地下水三维不稳定流模型来刻画汾河二库地下水下游区域流动的基本规律。运用识别后的模型预测了未来2010年和2015年水库不同蓄水位条件下的地下水动态变化。模拟结果表明,汾河二库的建成使周围地下水流动发生了变化,水库蓄水造成流域地下水位的上升,但对兰村水源地的影响有限。
The paper established a Hydrogeological conceptual model of Second Fenhe Reservoir and its downstream region,and then established a three-dimensional instability groundwater flow model to characterize the basic law of the Second Fenhe area of groundwater flow downstream,using standard software visualization Visual Modflow on the basis of information on groundwater-head long-recognition model of the hydro-geological parameters.To use the identified model to predict the future in 2010 and 2015,reservoir storage spaces under the conditions of the different groundwater dynamics.Simulation results show that the completion of Second Fenhe Reservoir to make a change in groundwater flow around the reservoir water storage basin caused by the rising water table,but it impacts limited on the Lan-cun Water Sources.
