摘要

本文建立了含化学物质分布的浅水流动一维有限元模型。确定性模型基于污染物的非定常流动和对流-扩散-衰变，允许在时空域的任何点评估化合物的浓度值。所采用的数值方法在稳定性和准确性方面具有计算成本效益，并且可以预测浓度的演变。

Shallow Water 1D Model for Pollution River Study

In this paper a finite element 1D model for shallow water flows with distribution of chemical substances is presented. The deterministic model, based on unsteady flow and convection-diffusion-decay of the pollutants, allows for evaluating in any point of the space-time domain the concentration values of the chemical compounds. The numerical approach followed is computationally cost-effectiveness respect both the stability and the accuracy, and by means of it is possible to foresee the evolution of the concentrations.
