| 摘 要： | 本文总结了连续源和瞬时源的示踪模拟与分析方法,说明怎样利用示踪模拟为大江大河的事故污染和正常纳污的污染输移扩散时空分布计算预测提供一种简便实用的模式,并讨论了在大江大河中污染输移扩散的某些特性.认为离散系数主要应由摩阻流速U※和湿周P决定。

| Abstract: | This paper demonstrates how to work out a model from tracer test to predict pollutant dispersion and transport after an accident or normal release in large river. Some characteristics of pollutant dispersion and transport in large river is disscused. It is concluded that, dispersion coefficients of river is mainly relative to shear velocity U and wetted perimeter P. |
