The Anatomy of Convection Under Lake Ice: Reynolds Stresses and Convective Energy Budget From In Situ Observations
Rapid drought-to-flood weather whiplash amplifies climate change governance failure
Prediction of Hydroclimatic Anomalies Using a New Isotope Precipitation Index
The authors used stable water isotopes to trace the origin of precipitation and are developing a new, isotope-based Evaporation and Moisture Recycling Index (iEMI). The iEMI can identify anomalous dry periods and links evaporation-driven precipitation to droughts in Europe, Africa, and Australia. This innovative index can help improve drought monitoring and optimize water management worldwide.
Unravelling the Role of Surface Water–Groundwater Connectivity in the Andean Páramo
Effects of temporary streamflow interruption on hyporheic oxygen dynamics
This study provides high-resolution, field-based evidence of the importance of accounting for short-term flow interruptions in river management strategies. It demonstrated that a one-day streamflow interruption of the side channel of the River Erpe caused a significant decrease in diel surface water oxygen amplitude and porewater oxygen concentrations, as well as a metabolic shift after rewetting.
Enhancement of Hyporheic Flow and Solute Transport by Random Burrow- and Mound-Induced Bioturbation
This study examined how bioturbation alters sediment structure and surface roughness, and how this influences hyporheic exchange and biogeochemical processes. It reveals that irregular burrow galleries promote deeper and spatially heterogeneous solute penetration by generating tortuous and highly connected flow paths within the sediment.
A Novel In Situ Experimental Setup for Studying the Impact of Bedform Celerity on 2D Oxygen Distribution in the Hyporheic Zone of Streams
The authors investigated the influence of dynamic hyporheic zones. They developed of a novel field-based setup that enabled the simultaneous monitoring of oxygen dynamics and bedform migration in a stream. Contrary to what has been reported in several studies, they observed more strongly oxygenated bedforms at the highest velocity studied.
Coupling an Isotope-Enabled Global Spectral Model (IsoGSM) With Hydrological Modelling Using Streamflow-Isotope-Based Correction
Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments
Enhancing process interpretation with isotopes: potential discharge-isotope trade-offs in ecohydrological modelling of heavily managed lowland catchments
The authors enhanced a tracer-aided hydrological model to help constrain estimates of ecohydrological partitioning and water balance compartments in sub-catchments of the Middle Spree catchment. They disentangled ecohydrological funtioning in this ET dominated region despite the complexity of the heterogeneous landuse, extensive hydraulic infrastructure and long legacy of intensive management.
