Uncertainty Quantification of Large-Eddy Simulation Results of Riverine Flows: A Field and Numerical Study

  title={Uncertainty Quantification of Large-Eddy Simulation Results of Riverine Flows: A Field and Numerical Study},
  author={Kevin Flora and Ali Khosronejad},
We present large-eddy simulations (LESs) of riverine flow in a study reach in the Sacramento River, California. The riverbed bathymetry was surveyed in high-resolution using a multibeam echosounder to construct the computational model of the study area, while the topographies were defined using aerial photographs taken by an Unmanned Aircraft System (UAS). In a series of field campaigns, we measured the flow field of the river using the acoustic Doppler current profiler (ADCP) and estimated…

Equivalent Roughness Height for Plane Bed under Steady Flow
This paper presents a new relationship between the roughness height and the main hydrodynamic and sediment parameters for plane beds under steady current conditions. In order to derive such a…
Velocity and concentration profiles in sheet-flow layer of movable bed
Sheet-flow layer of movable bed in steady currents has been investigated experimentally, using four kinds of sediment. Velocity and concentration profiles as well as flow resistance were measured…

On the Impact of Bed-Bathymetry Resolution and Bank Vegetation on the Flood Flow Field of the American River, California: Insights Gained Using Data-Driven Large-Eddy Simulation
AbstractHigh-fidelity models can simulate many detailed hydrodynamic features of flow in natural rivers. However, it is challenging to explicitly capture the effects of highly complex bathymetry an...
Turbulent flow characteristics around a non-submerged rectangular obstacle on the side of an open channel
The three-dimensional flow structure and turbulence characteristics around a non-submerged rectangular obstacle in an open channel are explored using numerical simulation. In particular, a low…
