Determination 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 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...
متن کاملEvaluation of an analytical model for hydraulic resistance of submerged vegetation
The hydraulic resistance of vegetation can play a major role in the hydrodynamics of vegetated streams or rivers with extensive natural floodplains. Contrary to commonly used wall roughness methods, vegetation penetrates the flow field causing drag and, subsequently, additional energy losses. Klopstra et al. (1997) derived an analytical solution of the flow velocity profile over and through a f...
متن کاملTurbulent 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 کاملFlow through Non-submerged Vegetation: a Flume Experiment with Artificial Vegetation
Vegetation growing in the water along rivers plays an important role on the hydrodynamic behavior, on the ecological equilibrium and on the characteristics of the river. It has effects on the flow resistance and, as a result, has a large impact on water levels. The influence of non-submerged vegetation on flow is not so clear as yet; it needs to be further studied. The Acorus Calmus L is a kind...
