Turbulent Flow in Wetlands with Submerged and Floating Vegetation
Turbulent Flow in wetlands with submerged and floating aquatic plants was studied by applying Boit’s poroelastic theory to turbulent flow. The velocity distribution formulas were described by solving the modified Bessel equations. The effects of plant porosity and turbulent coefficient on the velocity distribution, shear stress distribution and energy relations were analytically derived. Severa...
متن کاملMean Velocity Modeling of Open-Channel Flow with Submerged Rigid Vegetation
Abstract—Vegetation affects the mean and turbulent flow structure. It may increase flood risks and sediment transport. Therefore, it is important to develop analytical approaches for the bed shear stress on vegetated bed, to predict resistance caused by vegetation. In the recent years, experimental and numerical models have both been developed to model the effects of submerged vegetation on ope...
متن کاملDetermination of flow resistance caused by non-submerged woody vegetation
This paper investigates the determination of flow resistance caused by stiff and flexible woody vegetation. A new procedure has been developed which allows the determination of friction factor f or Manning’s n using measurable characteristics of vegetation and flow. The procedure is capable of predicting flow resistance due to: (1) leafless bushes or trees and (2) leafy bushes or trees. The app...
متن کاملVertical Velocity Distribution in Open-Channel Flow with Rigid Vegetation
In order to experimentally investigate the effects of rigid vegetation on the characteristics of flow, the vegetations were modeled by rigid cylindrical rod. Flow field is measured under the conditions of submerged rigid rod in flume with single layer and double layer vegetations. Experiments were performed for various spacings of the rigid rods. The vegetation models were aligned with the appr...
متن کاملA phenomenological model for the flow resistance over submerged vegetation
[1] The bulk velocity Ub in streams is conventionally estimated from Manning’s equation, but difficulties remain in parameterizing the roughness coefficient n when the streambed is covered with vegetation. A two-layer velocity model is proposed to determine n and Ub for the submerged vegetation case. The modeled n is derived as a function of flow and vegetation properties that can be inferred f...
