太原盆地地下水污染数值模拟

NUMERICAL SIMULATION OF GROUNDWATER POLLUTION IN TAIYUAN BASIN

提出了一个越流含水层系统地下水污染的数学模型．模型应用于描述太原盆地地下水污染，Ｃｌ－浓度和水位计算结果与野外观测结果拟合良好．文中还探讨了现行溶质运移模型求解中井点附近容易出现不合理结果的原因，并从理论上给出了正确的表达式．

A mathematical model for groundwater pollution in a leaky aquifer system is presented. This model is applied to describing the groundwater pollution in Taiyuan Basin. The simulated values of the concentration of Cl in groundwater and Hydraulic head agree very vell with the field data. The reasons are also discussed why unreasonable results easily occur near well point in the present solute transport simulation. In addition, the exact expressions of various source/sink terms in the advection dispersion equation are derived theoretically.
