Emergent Headwater Types for Watershed Monitoring, Research, and Planning

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Headwaters—that is headwater streams and the watersheds they drain—strongly influence water quality, ecosystem services, and hydrologic connectivity, yet remain poorly mapped, monitored, and understood at large spatial scales. Using available spatial data to classify headwater “types” could therefore enhance the utility of sparse monitoring ...

Emergent Regimes of River Meandering and Permafrost Extent in Arctic Floodplains

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Permafrost in Arctic floodplains impacts carbon stores, ecosystems, and infrastructure, yet the processes controlling its distribution remain poorly constrained. Here we present a numerical model for the coupled evolution of river meandering and floodplain permafrost that captures the competition between bank erosion and permafrost growth.

How Much Water Can Be Seasonally Buffered by China's Largest Floodplain Lake? A Refined Estimate From SWOT

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Poyang Lake, China's largest floodplain lake, plays a crucial role in regional hydrology by seasonally regulating water to mitigate floods and sustain extensive wetland ecosystems. However, complex hydrodynamics and significant spatial hydraulic gradients often invalidate the traditional “flat‐water” assumption, making reliable estimation of ...

A two‐tier, reference‐informed framework for soil health assessment: Minimum indicator sets and ecologically dynamic thresholds

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Soil health underpins crop productivity and sustainability, but current soil health assessment frameworks struggle to balance global standardization with regional dynamic ecological realism. Indicators vary widely across soils and climates, often leading to one‐size‐fits‐all thresholds that penalize producers in inherently low‐capacity soils ...

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Revealing the Discrepancy Between Ecosystem Service Flows and Public Perception in Heavily Impacted Lowland Rivers of Armenia

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT River ecosystems are increasingly vulnerable to intensified human pressures associated with population growth and rising living standards, leading to structural changes and altered ecosystem service (ES) provision. The lower course of the Hrazdan River (Armenia) exemplifies these impacts, as it flows through Yerevan, the capital city, and ...

Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

The Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.
