Restoration Ecology, Volume 34, Issue 4, May 2026.Abstract Introduction Seagrass meadows, composed of submersed aquatic vegetation (SAV), are changing due to climate change, increasing the need for adaptive restoration approaches such as incorporating native species that thrive under new environmental regimes.

Bar dynamics and sediment transport pulses in gravel-bed channels
E3S Web of Conferences, 2018 Mountain rivers exhibit sediment transport rate fluctuations that often cover more than two orders of magnitude. Bedform migration is often cited as the key process that causes giant fluctuations in the sediment transport rate.

Laser Ranging For Monitoring Water Waves In The New Deltares Delta Flume [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 Currently a new wave flume for hydraulic experiments near to prototype scale is under construction at Deltares. In the flume, modern measurement equipment will be installed. One of the potential sensor techniques is Terrestrial Laser Scanner (TLS) based

The emerging use of magnetic resonance imaging to study river bed dynamics [PDF]
, 2015 The characterization of surface and sub-surface sedimentology has long been of interest to gravel-bed river researchers. The determination of surface structure is important as it exerts control over bed roughness, near-bed hydraulics and particle ...

Hydraulic or Seepage Erosion: What Drives Bank Collapse in Tidal Environments?
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The collapse of channel banks in tidal environments has typically been interpreted using fluvial concepts that prioritize hydraulic (flow‐driven) erosion. Yet daily tidal fluctuations trap pore water in channel banks, potentially producing sustained seepage flows capable of triggering collapse even without strong currents.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Bedload transport of sediment mixtures is fundamental to river morphology and impacts aquatic ecology. Adding fine grains enhances coarse‐grain transport, yet controlling mechanisms remain elusive. Employing discrete element simulations, we examine how fine‐grain size and proportion influence coarse‐grain flux.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Laboratory experiments measured velocity and bedload transport in vegetated channels under current‐dominated, combined wave‐current conditions. Waves and vegetation, respectively, introduced temporal and spatial heterogeneity in the velocity, which significantly impacted sediment transport rate.

Bedform dimensions under supply limited conditions [PDF]
, 2008 The volume of mobile sediment on the river bed is the primary control on the dimensions of the bed forms that develop. If an unlimited supply of sediment is available the bed form dimensions which develop are determined by the water depth, the flow ...

Drag Coefficients of a Long Flexible Circular Cylinder with Wake Interference [PDF]
, 2009 Drag coefficients of the downstream cylinder in a tandem arrangement of two models aligned with the flow are shown in this work. The models, which experienced vortex-induced vibrations with wake interference, had an external diameter of 16 mm and a ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Laboratory experiments investigated how the presence of biofilm and particle size influenced deposition in both bare and vegetated channels. Both abiotic and biotic sediment beds were considered, with the biotic beds containing Extracellular Polymeric Substances (EPS). As current magnitude and turbulent kinetic energy increased, particles were
