Unsteady 1D flow model of compound channel with vegetated floodplains
In areas that are occasionally inundated by floods, it is essential to know the quantity and density of vegetation that can be allowed while avoiding flooding beyond the intended floodplains. An unsteady flow model was developed for a channel with vegetated floodplains, to take into account the retention effects of the vegetated areas on flood wave conveyance. A one-dimensional (1D) unsteady fl...
متن کاملmean flow and turbulence in compound channels with vegetated floodplains
the study of flow in compound channels with vegetated floodplains is essential to assessing the development of the stage-discharge relationship and sediment and pollutant transport. the present study experimentally investigated mean flow and turbulence characteristics in a prismatic compound channel. the experimental program consisted of vegetated and non-vegetated floodplains with different re...
متن کاملDetermination of flow resistance of vegetated channel banks and floodplains
Flow resistance due to vegetation may greatly affect the conveyance of a channel, and thus evaluating the resistance is a critical task in river engineering and restoration. Therefore, flow resistance of natural willows and sedges was studied in a laboratory flume. The aim was to investigate, how type, density and combination of vegetation, flow depth and velocity influence vegetal drag or fric...
متن کاملUnsteady 1D flow model of a river with partly vegetated floodplains - application to the Rhine River
A relatively simple unsteady flow model was proposed which estimates velocities, friction factors and the components of discharge in the main channel and on the floodplains simultaneously. Bottom roughness of the main channel and the floodplains, the flow resistance of vegetation on the floodplains and the flow resistance caused by the momentum transfer between the main channel and the floodpla...
متن کاملNumerical analysis of on the effects of Hydrokinetic turbine presence in flow structure of a compound open-channel
In the recent years, due to the hydropower plants environmental problems, hydrokinetic turbine usages has been increased. Using such turbines in rivers modify natural flow-field. In previous studies, impacts of turbine on the flow-field just only in rectangular open-channel is studied. In this work, the effects of hydrokinetic turbine in a straight compound channel has been numerically studied ...
