Numerical Simulation of Shallow Groundwater Flow and Solute Transport in Typical Areas

根据典型地区地下水动态和溶质运移情况,结合水文地质条件和其他资料,建立了相应的水文地质概念模型。利用有限元数值模拟软件FEFLOW实现了对研究区地下水流系统和溶质运移的模拟。在水位过程线拟合、水位误差分析和溶质相关性分析的基础上,对地下水流系统和溶质运移模型进行了识别、校验,并利用所建立的数值模型预测了研究区地下水溶质运移演化情况。

According to the groundwater dynamic and solute transport situation of study area, combining with the hydrogeological conditions and rel- ative data, this paper established a hydrogeological conceptual model. The finite element numerical simulation software FEFLOW was applied to simulate the subsurface flow system and solute transport. Based on water level line fitting, error analysis of groundwater level and correlation analy- sis of solute, the coupled model was proved to be reliable due to the effectiveness of identification and verification. Finally, the evolution of solute transport of groundwater in the study area was predicted by using the established numerical model.
