Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

Water and Environment Journal, EarlyView.
Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Strategies for Mitigating Seasonal Heavy Metal Release in River Sediments Using Natural Mineral‐Based Materials

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT This study presents an ecological and geochemical assessment of trace element contamination in the Huyva River (Ukraine), a right tributary of the Teteriv River that supplies drinking water to Zhytomyr and nearby settlements. The research involved monitoring key physicochemical parameters, including pH, mineralization, hardness, and major ion ...

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Harnessing Community Science to Address Flood Risks and Build Climate Resilience With Nature‐Based Solutions (NbS)—A Case Study From the Quad Cities Region

Community Science, Volume 5, Issue 1, March 2026.
Abstract Urban regions situated along major river systems are increasingly facing flood risks, driven by the combined effects of rapid urbanization and intensifying climate change. The Quad Cities region, comprising Davenport and Bettendorf in Iowa, and Rock Island, Moline, and East Moline in Illinois, is vulnerable to flood hazards caused by extreme ...

Geospatial Analysis of Population Exposure to Flooding in the Sudd Region, South Sudan

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The Sudd wetland in South Sudan extends over 90,000 km2. Large‐scale flood events in recent years (2019–2022) are said to have led to the displacement of an estimated 1.8 million people in total. However, these estimates are approximate and to date there has not been a systematic analysis of population exposure to flooding in the Sudd region ...

Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate ...

Hydrochemical Characteristics of Four Retreating Glacier Forefields Off the Coast of Admiralty Bay (King George Island, Maritime Antarctic): Diverse Sources of Metals and Metalloids

Land Degradation &Development, Volume 37, Issue 4, Page 1330-1352, 28 February 2026.
ABSTRACT This study examines the impact of geological, marine and anthropogenic sources on metal and metalloid concentrations in the forefields of four glaciers (Ecology, Sphinx, Tower and Windy) on King George Island, Antarctic. Water samples were collected at the beginning and end of the hydrological season (austral summer, December 2021 to February ...

When Rain Meets Surge: Assessing Future Typhoon‐Driven Compound Flood Hazard Profiles in a Rapidly Urbanizing Delta

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Typhoon‐induced Compound Flood (TCF), driven by the combined impact of extreme rainfall and increasing coastal water level (CWL), poses a substantial threat to urban safety. This study presents a framework for assessing the future compound flood hazard profiles in a coastal megacity in the Delta region of southern China.
