Alluvial ridge morphology on avulsing rivers

Sedimentology, EarlyView.
ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

Organic‐matter sources and stability in kettle‐hole sediments: A combined thermogravimetric and isotopic approach

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Kettle‐holes are small but biogeochemically active landscape elements that integrate terrestrial inputs and influence carbon and nitrogen cycling. However, the stability and sources of organic matter (OM) in kettle‐hole sediments remain poorly understood.

Unravelling β‐Diversity and the Role of Small Streams in Shaping Fish Communities Using a National‐Scale eDNA Database

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
The role of river size on fish communities remains underexplored in freshwater ecology. Small streams, despite accounting for 75% of stream length, are more vulnerable to human impacts and often lack legislative protection. Nevertheless, they can serve as refuges and rearing areas for fish, including rare or threatened species.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...
