| 摘 要： | 感潮河网地区的污染物质混合输移的机制十分复杂,本文结合广州河段1987年枯水期的水文水质同步实测资料,利用理论分析,室内实验及计算机模拟识别等方法,对感潮河网地带的纵向离散系数进行了全面的研究。对天然河流的振荡剪切离散提出了一个实用的解析分析方法;通过实验研究分析了等效离散系数D与振荡剪切离散系数D的关系;利用实测数据分析了典型断面的D/D的基本特征,并通过计算机模拟,为广州河段提供了D的预测公式。

| Abstract: | The mixing and transporting mechanism of contamination in tidal river networks is very complex. Based on theoretical analysis, test in laboratory and computer modelling, in this paper was studied deeply the longitudinal dispersion in tidal networks by means of hydrology and water quality data observed on the Guangzhou tidal networks of the Pearl River in December 1987.The main problems to be discussed are the determination of oscillatory shear dispersion coefficient on natural river, the relation between equal-effective dispersion coefficient and oscillatory shear dispersion coefficient, and predicting methods of dispersion coefficient. |
