Flood inundation prediction

PD Bates - Annual Review of Fluid Mechanics, 2022 - annualreviews.org
Every year flood events lead to thousands of casualties and significant economic damage.
Mapping the areas at risk of flooding is critical to reducing these losses, yet until the last few …

From discovery to recognition of periodic large scale vortices in rod bundles as source of natural mixing between subchannels—a review

L Meyer - Nuclear Engineering and Design, 2010 - Elsevier
The mixing of cooling fluid in rod bundles from one subchannel to another through the gaps
between the rods reduces the temperature differences in the coolant as well as along the …

Shear instability and coherent structures in shallow flow adjacent to a porous layer

BL White, HM Nepf - Journal of Fluid Mechanics, 2007 - cambridge.org
Results are presented from an experimental study of shallow flow in a channel partially
obstructed by an array of circular cylinders. The cylinder array is a model for emergent …

A vortex‐based model of velocity and shear stress in a partially vegetated shallow channel

BL White, HM Nepf - Water Resources Research, 2008 - Wiley Online Library
This paper presents a method for predicting the distributions of velocity and shear stress in
shallow channels with a boundary of emergent vegetation. Experiments in a laboratory …

Comparison of flexible and rigid vegetation induced shear layers in partly vegetated channels

G Caroppi, K Västilä, P Gualtieri… - Water Resources …, 2021 - Wiley Online Library
Natural riparian vegetation generally presents a complex hydrodynamic behavior governed
by plant morphology and flexibility. By contrast, hydrodynamic processes in partly vegetated …

Lateral momentum flux and the spatial evolution of flow within a confluence mixing interface

BL Rhoads, AN Sukhodolov - Water resources research, 2008 - Wiley Online Library
Mixing interfaces at confluences have been viewed as analogous to shallow mixing layers in
which lateral fluxes of momentum generally are viewed as unimportant. This investigation …

Analytical modelling of sidewall turbulence effect on streamwise velocity profile using 2D approach: A comparison of rectangular and trapezoidal open channel flows

JH Pu, M Pandey, PR Hanmaiahgari - Journal of Hydro-Environment …, 2020 - Elsevier
Natural earth-bounded channel flows usually subject to various sidewall turbulences, ie in
the form of secondary currents, due to non-constant channel shapes at different sections …

Compound open-channel flows: effects of transverse currents on the flow structure

S Proust, VI Nikora - Journal of Fluid Mechanics, 2020 - cambridge.org
The structure of free-surface flows in a straight compound channel was investigated in a
laboratory flume, consisting of a central smooth-bed main channel (MC) and two adjacent …

Stage-discharge prediction for straight and smooth compound channels with wide floodplains

KK Khatua, KC Patra, PK Mohanty - Journal of hydraulic …, 2012 - ascelibrary.org
A modified expression to predict the boundary shear distribution in compound channels is
derived and is found to provide significant improved results. The practical method to predict …
