Abstract: |
The studies of velocity distribution, flow resistance, the turbulent mechanism and the migration of pollutants in environmental channels are introduced at home and abroad. It is pointed out that the real aquatic plants should be introduced and the similarity of branch leaves of different plants should be studied. The simulation of the shape and temper of plants, the quantitative correlation between the toughness of vegetation, the density of vegetation, the submerging percent and flow structures, contaminant migration need to be solved. The influence of boundary effect of plants on flow characteristics in areas with and without plants, and the interaction between two areas should be further studied. Influence of plants on the settlement, migration and re-suspend process of sediments should be studied. Researches on flow structures and contaminant migration in bend channels should also be developed.
