Morphological resilience to flow fluctuations of fine sediment deposits in bank lateral cavities
TLDR
In this paper, the authors investigated the resistance and resilience of the sediment deposits in the banks of a river during high flow and flushing events, and found that the resilience of sediment deposits is strongly dependent on the flow field and the mass exchange between the main channel and the cavities.About:

Floodplain Land Cover and Flow Hydrodynamic Control of Overbank Sedimentation in Compound Channel Flows
Carmelo Juez,Carmelo Juez,Carmelo Juez,C. Schärer,H. Jenny,Anton Schleiss,Mário J. Franca,Mário J. Franca +7 more
TL;DR: In this paper, the existence and pattern of sedimentation are conditioned by both the hydrodynamic variables (the flow-depth ratio and the width ratio) and the floodplain land cover simulated in terms of smooth walls, meadow-type roughness, sparse-wood type roughness.

Investigating the Flow Hydrodynamics in a Compound Channel with Layered Vegetated Floodplains
Muhammad Ahmad,Usman Ghani,Naveed Anjum,Ghufran Ahmed Pasha,Muhammad Kaleem Ullah,Afzal Ahmed +5 more
TL;DR: In this article, a numerical study was carried out to investigate the complex 3D flow structures with the vertically layered vegetation placed over the floodplains in a symmetric trapezoidal compound channel, and the simulations were conducted using a Computational Fluid Dynamics (CFD) code FLUENT, whereas a Reynolds Averaged Navier-Stokes (RANS) technique based on Reynolds stress model (RSM) was implemented for turbulence closure.

Depth-averaged unsteady RANS simulation of resonant shallow flows in lateral cavities using augmented WENO-ADER schemes
TL;DR: It is shown that depth-averaged unsteady Reynolds averaged Navier Stokes (URANS) models based on the Shallow Water Equations are a suitable choice for the resolution of turbulent shallow flows with sufficient accuracy in an affordable computational time.

TL;DR: In this article, Naiman et al. pointed out that harnessing of streams and rivers comes at great cost: Many rivers no longer support socially valued native species or sustain healthy ecosystems that provide important goods and services.

Stream Ecology: Structure and Function of Running Waters
TL;DR: An overview of the diversity of rivers and streams, including some of the causes of this diversity, and some of their consequences, can be found in this article, where the authors provide a roadmap for individual chapters that follow, rather than define terms and explain principles in any detail.
Journal ArticleDOI
Modern Global Climate Change
TL;DR: It is clear that these changes will be increasingly manifested in important and tangible ways, such as changes in extremes of temperature and precipitation, decreases in seasonal and perennial snow and ice extent, and sea level rise.

Biological Effects of Fine Sediment in the Lotic Environment
Paul J. Wood,Patrick D. Armitage +1 more
TL;DR: A holistic approach to the problems associated with finesediment is outlined to aid in the identification of sediment sources, transport, and deposition processes in the river catchment, and the multiple causes and deleterious impacts associated with fine sediments on riverinehabitats, primary producers, macroinvertebrates, and fisheries are identified.

Unified view of sediment transport by currents and waves. I: Initiation of motion, bed roughness, and bed-load transport
TL;DR: In this paper, the effect of fine silt on the bed composition and on initiation of motion (critical conditions) of sediment beds over the full range of conditions (silts to gravel) is discussed.
