Modeling of Groundwater Quantity and Quality in Jiamusi City

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.
