摘要: The influence of rigid unsubmerged vegetation on flow structure and turbulent kinetic energy gradually varied are experimentally investigated in this research. Natural reed stems different densities employed to examine the effects rivers. results reveal that existence significantly changes state from type M1 M2 section. traditional power law describing vertical velocity profile is evidently invalid when density becomes high. With irregularity index proposed research, vegetated reach can be exponentially described relation density. Furthermore, found increase a maximum value near end section potential localized erosion area. research have significances river ecological restoration applications utilizing aquatic vegetation.
