Popis: | In rivers, alternating bars are often covered with vegetation and provide favorable spaces for natural habitat environment. Then one has to know more about the flow and sediment transport around vegetation-covered bars, which bring about river-morphological change during floods. In present study, river bed deformation around vegetation-covered alternating bars is discussed by flume experiments and numerical calculations with k-e turbulence model. The results show that vegetation over alternating bars changes the formation of main channel and has possibility to control the spatial variation of river bed. |
