Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

The Effects of Space–Time Dynamics of Precipitation on the Shape and Timing of Streamflow Event Hydrographs

Hydrological Processes, Volume 39, Issue 11, November 2025.
The analysis of 93 862 hourly streamflow events using interpretable machine learning shows that their timing is controlled by the location of the corresponding rainfall relative to the river network and outlet. Moreover, space–time interaction of precipitation and wetness states is particularly crucial for the shape and timing of large streamflow ...

Modelling of manure production by pigs and NH3, N2O and CH4 emissions. Part II: effect of animal housing, manure storage and treatment practices

Animal, 2010
A model has been developed to predict pig manure evolution (mass, dry and organic matter, N, P, K, Cu and Zn contents) and related gaseous emissions (methane (CH4), nitrous oxide (N2O) and ammonia (NH3)) from pig excreta up to manure stored before ...

Combined Gravel Augmentation and Flood Control Area to Rehabilitate Riverbed Diversification: Lesson From Unexpected Effects of a 30 Years Flood (Upper Rhine)

River Research and Applications, Volume 41, Issue 9, Page 1819-1831, November 2025.
ABSTRACT Gravel augmentation measures are common practices in the context of large, bypassing river reaches, with the aim of mitigating the adverse effects of sediment starvation conditions that frequently occur below dams. However, the impacts of these structures on bedload transport reactivation and habitat diversification are typically transient due

Unveiling the Stochasticity of Bank Erosion: A Hybrid Deterministic and Stochastic Modeling Approach

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract This paper presents a new hybrid deterministic‐stochastic river morphodynamics numerical modeling approach that integrates a hydrodynamic model (deterministic) with a bed morphodynamic model (deterministic) and a bank erosion model (Markovian stochastic).

Quantifying the Form‐Flow‐Saltation Dynamics of Aeolian Sand Ripples

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 10, October 2025.
Abstract Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. However, these attributes also make ripples excellent flow indicators, and they have been used extensively in planetary locations for this purpose.

Projected Climate Change Impacts on Groundwater–Surface Water Connectivity in a Compartmentalized Mountain Headwater Bedrock Aquifer

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract How mountain headwaters and their groundwater‐dependent ecosystems will respond to future climate change remains largely unknown. These challenges stem from the difficulty of gathering relevant hydrological observations and implementing modeling strategies suited to data‐scarce systems.

Pratiquer les terres riveraines : géographie d’un dialogue à la frontière des cours d’eau

Belgeo
The riparian lands along the Eygues River, located in the Baronnies Provençales massif (Southern Alps, France), were long considered marshland before being permanently developed for agriculture. This transformation took advantage of the river’s proximity
