分汊型河道水流运动特性和污染物输移规律研究进展
Advances in flow characteristics and pollutant transport laws in braided rivers
摘要
Abstract
The relevant researches on the flow characteristics and pollutant transport laws in braided rivers were reviewed. They were summarized from four aspects, namely the flow characteristics of bifurcation, confluence and the whole braided river, and the pollutant transport laws in braided rivers. Firstly, as to the flows at the bifurcation and confluence of braided rivers, the research achievements from the ID and 2D flow characteristics including energy loss, water level variation, flow separation and so on to the 3D flow structure and turbulent characteristics were introduced. Secondly, the flow characteristics of the whole braided river were described by means of field tests, laboratory tests and numerical simulations. Thirdly, the relevant researches on the pollutant transport laws in braided rivers were reviewed and analyzed, and the numerical simulations were found out to be the main method. Finally, some further problems about the flow characteristics and pollutant transport laws in braided rivere were put forward, especially the experimental studies on the pollutant transport mechanism under different discharge modes, pollutant densities and braided forms.关键词
