珠江广州河段纵向离散特性研究
Study on Longitudinal Dispersion in Guangzhou Reach of the Pear River

摘要: 根据珠江广州河段多年观测的流速分布资料和1987年、1988年两次大规模水文水质同步观测资料,利用非恒定流离散理论,对珠江广州河段的离散特性进行了分析,给出了纵向离散系数的瞬时值、潮平均值和等效值。Abstract: Accordint to the field data of velocity distribution in several years and the hydrology-water quality in 1987 and 1988,thd longitudinal dispersion in Guangzshou reach of the Pear River was analyzed,and the instantaneous value,the tidal averaged value and the equifinal value of dispersion coefficients were obtained by using the dispersion theory of unsteady flow.
