Spatiotemporal Dynamics and Evolution of Groundwater‐Dependent Ecosystems in the West Liao River Plain

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Groundwater‐dependent ecosystems (GDEs) are essential to ecological stability in semi‐arid regions, yet their identification and mechanistic interpretation remain constrained by limited long‐term observations and insufficient model interpretability.

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

To Which Extent the Surface Water Ocean Topography (SWOT) Mission Is Currently Able to Monitor Water Surface Elevation and Extent on the French Lakes?

Earth and Space Science, Volume 13, Issue 6, June 2026.
Abstract This study (July 2023–December 2025) assesses the SWOT satellite's ability to measure water surface elevation (WSE) and surface water extent (SWE) over diverse French lakes. WSE estimates from SWOT were compared to in situ gauge data and conventional radar altimetry, while SWE was evaluated using the Global Water Watch (GWW) database.

NDWI-BASED TECHNIQUE FOR DETECTION OF CHANGE DATES OF THE GROWING SEASONS IN RUSSIAN SUBARCTIC [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
Abstract. The paper describes a technique for automated analysis of the annual graphs of Normalized Difference Water Index, which enables to allocate framing dates of the spring, summer and autumn growing seasons. The approach proposed and used for detection of growing season dates allows to detect beginning and ending dates for summer season (when the

The Shrinking Caspian Sea: Eco‐Hydrological Responses to Human and Climate Pressures

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract The Caspian Sea, the Earth's largest inland water body, faces water level decline, drawing comparisons to the collapse of the Aral Sea. Unlike the Aral Sea, the relative roles of climatic variability, hydrological changes, and anthropogenic pressures on the Caspian Sea remain poorly understood.

Performance Evaluation of Automated Flood Inundation Mapping Techniques Using Multi‐Temporal Sentinel‐1 SAR Data

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT In recent times, the development of algorithms to delineate water surface maps has significantly boosted flood monitoring and mitigation efforts by utilizing dual polarization, multi‐temporal Sentinel‐1 synthetic aperture radar (SAR) data. The Sentinel‐1 mission, with its global land monitoring capability, has been widely employed for SAR ...

Assessing Ecological Connectivity for Loxodonta africana Across Transfrontier Conservation Areas in Southern Mozambique

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We present the first spatially explicit assessment of ecological connectivity for African bush elephant (Loxodonta africana) in southern Mozambique, spanning the Great Limpopo and Lubombo Transfrontier Conservation Areas. By integrating Resource Selection Function with landscape connectivity analysis, we provide spatially explicit prioritization of ...
