Flume experiments on macro‐roughness elements: Hydraulic response and potential influences on flood risk and habitat diversity

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Physical modelling of macro‐roughness elements for river restoration showed that backwater rise depends mostly on the relative structure width and approaching flow Froude number, with only minor differences among designs. Internal geometry modulated turbulent kinetic energy and flow partition between gap and wake.

A hybrid particle tracking algorithm for characterizing particle motions in pneumatic dispersion [PDF]

AIP Advances
Accurate measurement of particle motion in pneumatic dispersion is essential, yet challenging, because current imaging techniques cannot clearly resolve individual particles within dense agglomerations.

Flow resistance parameterization for large wood in two‐dimensional depth‐averaged models: Effects of flow condition, blockage, and sediment

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Using 16 flume experiments and 2D modeling, we show that large‐wood flow resistance is not a fixed property of wood porosity but varies systematically with flow condition, blockage and most strongly sediment‐shaped bed topography. The drag coefficient and Manning's n are interchangeable, but calibration is essential where scour occurs.

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, Volume 97, Issue 8, Page 4207-4222, August 2026.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Overland Flow Dynamics on a Cracked Soil Slope Under Drying‐Wetting Cycles: An Integrated Hydrological and Infrared Thermographic Study

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Although overland flow strongly governs soil erosion and sediment transport, its response to desiccation cracking induced by drying‐wetting cycles is not fully understood. This study addresses this gap through laboratory rainfall simulations on a slope model subjected to three drying‐wetting cycles.

Silicone-Based Molding Technique for Optical Flow Analysis in Transparent Models of Fluidic Components

Applied Sciences, 2018
Optical flow analysis methods such as particle image velocimetry can only be performed in fluid systems or components with optical access. Many fluidic components, such as metallic tubes, do not typically feature optical accessibility.

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Topography‐Based Particle Image Velocimetry of Braided Channel Initiation

Water Resources Research
River channels shape landscapes through gradual migration and abrupt avulsion. Measuring the motion of braided rivers, which have multiple channel threads, is particularly challenging, limiting predictions for landscape evolution and fluvial architecture.
