    Regional model and imbedded model of the Tianqiao karst groundwater system in the northeastern Ordos basin

    • 摘要: 如何评价陕北能源化工基地黄河西岸非完整岩溶水系统的地下水资源是一个难点。通过建立区域模型(1km×km)和嵌套水源地模型(100m×100m),利用大尺度的区域模型为小尺度的精细水源地模型提供边界水头。通过6种不同的开采方案模拟的结果,分析了黄河西岸水源地开采对周边水源地和区域地下水系统的影响,确定了天桥岩溶系统中各子泉域之间的相互关系和万家寨水库蓄水对地下水循环补给的影响,评价黄河西岸水源地可开采资源量为60×104m3/d。

       

      Abstract: How to evaluate the groundwater resources of the incomplete groundwater system on the west bank of the Yellow River in the Northern Shaanxi Energy and Chemical Industry Base is a difficult problem. In this study a regional model (1 km×1 km) was constructed, which provided specified head boundaries for the imbedded model (100 m×100 m). By using the results of simulation of six different exploitation plans, the influence of water mining on the adjacent well fields and the regional groundwater system was analyzed, and the interrelation between various sub-spring domains of the Tianqiao karst system and influence of the construction of the Wanjiazhai Reservoir on groundwater circulation was identified. At last the exploitable water resources in the water source area on the west bank of the Yellow River is estimated at 60×104 m3/d.
