DRIVING FORCE ANALYSIS AND POLLUTANT TRANSPORT SIMULATION IN GROUND WASER SYSTEM

本文介绍了地下水系统的概念和地下水系统分析方法,讨论了地下水系统模拟的驱动力场方法,推演出地下水驱动力方程和速度方程,建立了水流系统和污染质运移系统的模拟模型,并求得了它们的有限差分解,最后进行了实例模拟计算。

This paper deals with the silulations of flow and pollutant transport in ground water system on the basis of ground water driving force. The concepts of ground water system and system analysis are first introduced.The derivation of driving force and velocity differentiation equations are then presented,which provides the possibility to directly determine the velocity and the driving force fields.Thirdly,the flow model and pollutant transport model are setup,and finally,a finite difference solution of the models is given.Two computer programs are written for the simulation purpose. The example shows that the simulation results are satisfictory.
