佳木斯市地下水水量水质模型

Modeling of Groundwater Quantity and Quality in Jiamusi City

  • 摘要: 佳木斯市是一个以开采地下水为主要供水水源的城市.本文根据当地的水文地质条件,建立了佳木斯市的地下水的水量水质模型.用有限元法求解水量模型进行地下水资源评价.用特征有限元法求解水质模型进行地下水污染预测,该方法在求解对流一弥散方程时能有效地消除数值弥散和数值振荡,精度较高.为使该方法付诸实施,文中也提出了当利用特征有限元法求解时确定运动水质点所属单元的方法.

     

    Abstract: Jiamusi is an industrial city in north-east of Heilongjiang Province. Groundwater is the main source for water supply m this city. Two-dimensional mathematical models for groundwater resources and quality with their field applications in Jiamusi City were presented in this paper. The groundwater resource model was approached by a finite element method (FEM) and groundwater resource in this district was evaluated with the established model. The groundwater quality model was solved by a characteristic finite element method (CFEM). Numerical dispersion and oscillation were effectively reduced by using this method. Additionally, a simple but effective method was used to determine the serial number of the element where moving particle located, which is very important for the application of CFEM. The future distribution of contaminant concentrations in this area was predicted in the end of this paper.
