Dispersion Model for Varying Vertical Shear in Vegetated Channels
Publication: Journal of Hydraulic Engineering
Volume 137, Issue 10
Abstract
A dispersion model for a wide range of depthwise vertical shear is derived by using perturbation analysis and power () law velocity profile. For , the velocity profile provides linear shear, whereas provides nonlinear shear, and for , the velocity profile resembles the flow through emergent vegetation. The power law represented parametrically simulates well the complex shear profiles involved in emergent and submerged vegetated flows. The proposed model shows reasonable agreement with past data on vegetated flows for a wide range of nonlinear shear velocities.
