Knickpoint Morphology in Homogenous Substrates Controlled by Sediment Cover and Base‐Level Fall Rate

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Knickpoints can form spontaneously under constant forcing, without external perturbations. Flume experiments reveal three distinct morphologies, controlled by the balance between base‐level fall rate and sediment cover. A new conceptual model shows how erosion, sediment armouring and plunge pool dynamics govern knickpoint morphology, challenging ...

Detailed observations of edge scour of riprap scour protection for offshore-wind monopile and its effect on monopile’s bearing capacity

Applied Ocean Research
Large-diameter offshore monopiles are frequently subjected to scour hazards, necessitating the implementation of scour protection measures to mitigate soil erosion around the pile foundation.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

New Semiempirical Formula for Evaluating the Equilibrium Scour Depth at Bridge Piers

Journal of Hydraulic Engineering
Estimating the equilibrium scour depth ( y se ) at bridge piers is essential for both bridge foundation design and flood risk assessment. Traditional methods typically rely on empirical formulas derived from data-fitting procedures, which often result in significant overestimations of the local scour phenomenon.

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, Volume 8, Issue 8, Page 2521-2540, August 2026.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, Volume 97, Issue 8, Page 4138-4161, August 2026.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Nutrient Removal and Recovery: Hazenite Precipitation From Livestock Manure Wastewater

Water Environment Research, Volume 98, Issue 8, August 2026.
This study presents an optimized precipitation process for complex livestock wastewater, achieving > 90% concurrent removal of phosphorus, magnesium, and ammoniacal nitrogen. The system successfully drives targeted Hazenite (KNaMg2(PO4)2.14H2O) crystallization, recovering essential nutrients into a high‐value, slow‐release agricultural fertilizer ...

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 ...
