用特征有限无法预测大运河对某市潜水污染的影响
- PREDICTION OF GROUNDWATER POLLUTION FROM THE GRAND CANAL USING CHARACTERISTIC FIHITE ELEMENT METHOD
- 摘要：用特征有限元法预测了在井群开采条件下大运河水对某市潜水污染的影响, 计算了直到2020年的污染物相对浓度的分布。
- Abstract：The pollution of groundwater by polluted surface water from The Grand Canal under pumping condition was predicted using means of characteristic finite element method.The method is to decompose the transport equation into an advection problem and a residual dispersion problem. The advection contribution can be solved independently by characteristic line method and the dispersion one may be treated by Galerkin finite element approach.By this methods, the distributions of the relative concentrations of pollutants by 2020 were computed.
- Key words：Phreatic water characteristic finite element method, advective-dispersive equation groundwater pollution.
