Evaluation of ULS Bathymetry for Hydrodynamic Modelling [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The importance of accurate and reliable DTMs are paramount for hydrodynamic modelling. Currently, bathymetry is either not considered or a simpler mathematical representation of the river is created from observed cross sections for hydrodynamic models ...

Modelling Flood‐Induced Riparian Vegetation Disturbance and Hydro‐Morphodynamic Feedbacks

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
A process‐based framework links flood‐induced vegetation disturbance to hydro‐morphodynamic feedback by separating mechanical failure from postfailure outcomes, explaining spatial distribution patterns of washout, burial and localized embankment erosion during the 2019 Chikuma River flood.

Flood‐Scale Bedload Transport Dynamics From Acoustic Monitoring Compared With 2D Hydro‐Sedimentary Modeling

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Accurate estimation of bedload fluxes is critical to understanding sediment transport processes and associated channel evolution in gravel‐bed rivers, however, traditional direct measurements using samplers are time‐consuming and complex. To overcome these limitations, new indirect methods have been developed to estimate fluxes from bedload ...

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, Volume 73, Issue 5, Page 1378-1402, August 2026.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Beyond the panacea narrative: Evaluating the capabilities and limitations of remote sensing for biodiversity net gain in England

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Five priorities for integrating remote sensing into biodiversity net gain in England, highlighting the need for transparent, validated, and interpretable approaches that complement, rather than replace, ecological field surveys. Abstract In England, biodiversity net gain (BNG) is a relatively new mandatory approach applied to many development sites ...

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

River Research and Applications, Volume 42, Issue 6, Page 1115-1141, July 2026.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.
