Analysis of environmental dispersion in a wetland flow under the effect of wind: Extended solution--论文发表-槐文信课题组

简介

Abstract The accurate analysis of the contaminant transport process in wetland flows is
essential for environmental assessment. However, dispersivity assessment becomes
complicated when the wind strength and direction are taken into consideration. Prior studies
illustrating the wind effect on environmental dispersion in wetland flows simply focused on
the mean longitudinal concentration distribution. Moreover, the results obtained by these
analyses are not accurate when done on a smaller scale, namely, the initial stage of the
contaminant transport process. By combining the concentration moments method (the Aris'
method) and Gill's expansion theory, the previous researches on environmental dispersion
in wetland flows with effect of wind have been extended. By adopting up to 4th-order
moments, the wind effect—as illustrated by dimensionless parameters Er (wind force) and …
