Snow drought propagation and its impacts on streamflow drought in the Alps

Environmental Research Letters
Snow droughts, that is negative anomalies in annual snow storage, challenge water resources management in snow-rich catchments and their downstream regions because they can lead to succeeding streamflow droughts in the following melt season.

SWOT‐Fitted River Bathymetry for Global Hydrodynamic Models

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present a robust, global method to reconcile absolute water surface elevations (WSE) from the Surface Water and Ocean Topography (SWOT) mission with a large‐scale hydrodynamic model by iteratively correcting river bathymetry. After removing sensor and representativeness bias, we update riverbed elevations under DEM and min‐depth feasibility

From Soil to Canopy: Using Moisture Data From Soil and Tree Sensors to Predict Live Fuel Moisture and Guide Forest Management in a Mediterranean Coastal Woodland

Ecohydrology, Volume 19, Issue 7, October/November 2026.
ABSTRACT Ecosystem response to forest management and disturbance is governed by many factors and their interactions. This has historically made it difficult for practitioners to reach consensus on ideal management prescriptions and restoration activities.

Coupling Machine Learning and Physically Based Hydrological Models for Reservoir-Based Streamflow Forecasting

Remote Sensing
High-accuracy streamflow forecasting with long lead times can help promote the efficient utilization of water resources. However, the construction of cascade reservoirs has allowed the evolution of natural continuous rivers into multi-block rivers.

Investigating Ice Aggradation and Thermal Erosion Induced by Seasonal Water Flow in Cold Regions With a Cold Room Flume

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
A new experimental setup investigates the natural occurrence of meltwater flow over permafrost terrain creating thermal erosion or ice aggradation in periglacial environments. Figure: Water tracks (about 50 m in length up‐down) over permafrost hillslopes during end of June 2018 melt‐out. Photo credit by D. Fortier. ABSTRACT In periglacial environments,

The Decline of Seasonal Snowpack by Mid‐Century in Mountainous National Parks of the Iberian Peninsula

Hydrological Processes, Volume 40, Issue 10, October 2026.
Snow water equivalent change by mid‐century in five national parks of the Iberian Peninsula extracted from high‐resolution snowpack modelling and climate projections. A general snow cover reduction is documented in detail with large spatial variability within and between parks.

Variable Source Area Runoff Representation in the Water Erosion Prediction Project (WEPP) Model Using Multiple Overland Flow Elements

Hydrological Processes, Volume 40, Issue 10, October 2026.
This study presents a systematic evaluation of the effects of hillslope discretisation into multiple overland flow elements (OFEs) on watershed scale hydrologic process representation using the WEPP model. The key findings provide improved representation of: Lateral subsurface flow dynamics along the hillslope.

Catchment Hysteresis From Pathway Branching and Storage Trapping: A Two‐Parameter Mittag‐Leffler Closure and Its Application to the Great Catchment Hysteresis Challenge

Hydrological Processes, Volume 40, Issue 10, October 2026.
Answering the great catchment hysteresis challenge, we derive a catchment closure whose memory kernel follows from counting flow pathways and measuring how long water is detained. Applied to four Cumbrian micro‐catchments, it shows that the observed hysteresis index conflates event retention with genuine memory, and separating them weakens the inferred

The Impact of Model Resolution on the Water Balance of a Dryland Basin

Hydrological Processes, Volume 40, Issue 10, October 2026.
Dryland regions are poorly represented in large‐scale hydrological models. The spatial and temporal resolution of these models strongly influences model performance and affects the partitioning of precipitation into hydrological fluxes and storage changes.
