Hydrogeomorphology of Asymmetric Meandering Channels: Experiments and Field Evidence

Water Resources Research, 2023
Meandering channels display complex planform configurations with upstream (US)‐ and downstream (DS)‐skewed bends. Bend orientation is linked to hydrodynamics, bed morphodynamic regime, bank characteristics, riparian vegetation, and geological environment,

Extremes in dune preservation: controls on the completeness of fluvial deposits [PDF]

, 2015
Understanding sedimentary preservation underpins our ability to interpret the ancient sedimentary record and reconstruct palaeoenvironments and palaeoclimates.

The physics of wind-blown sand and dust [PDF]

, 2012
The transport of sand and dust by wind is a potent erosional force, creates sand dunes and ripples, and loads the atmosphere with suspended dust aerosols.

Monitoring Short-Term Morphobathymetric Change of Nearshore Seafloor Using Drone-Based Multispectral Imagery

Remote Sensing, 2022
Short-term changes in shallow bathymetry affect the coastal zone, and therefore their monitoring is an essential task in coastal planning projects.

Bedform characteristics in a gravel-bed river

Journal of Hydrology and Hydromechanics, 2017
Estimation of hydraulic and geometric parameters of a gravel-bed river such as dimensions of bedforms is very difficult task, although they play a fundamental role in river engineering projects.

Bedforms in a tidally modulated ridge and runnel shoreface (Berck-Plage; North France): implications for the geological record

BSGF - Earth Sciences Bulletin, 2018
Tidally modulated shoreface (TMS) corresponds to peculiar costal environments. The general morphology and the expressed bedforms are provided by the interplay of both waves and tides.

Wet subglacial bedforms of the NE Greenland Ice Stream shear margins

Annals of Glaciology, 2019
We describe elongate, wet, subglacial bedforms in the shear margins of the NE Greenland Ice Stream and place some constraints on their formation. Lateral shear margin moraines have been observed across the previously glaciated landscape, but little is ...

Combining SfM Photogrammetry and Terrestrial Laser Scanning to Assess Event-Scale Sediment Budgets along a Gravel-Bed Ephemeral Stream

Remote Sensing, 2020
Stream power represents the rate of energy expenditure along a stream reach and can be calculated using topographic data acquired via structure-from-motion (SfM) photogrammetry and terrestrial laser scanning (TLS).

Sediments and bedforms of the Harle tidal inlet (Wadden Sea, Germany)

Journal of Maps, 2023
The paper presents a map of sediment surface distribution and bedforms in the Harle tidal inlet, German Wadden Sea. Data collection, processing, and map editing were realized within the sublittoral mapping program of Lower Saxony national waters carried ...
