Factors affecting ammonium uptake in streams - an inter-biome perspective [PDF]

, 2003
The Lotic Intersite Nitrogen experiment (LINX) was a coordinated study of the relationships between North American biomes and factors governing ammonium uptake in streams. Our objective was to relate inter-biome variability of ammonium uptake to physical,

Nutrient cycling in bedform induced hyporheic zones [PDF]

, 2012
The hyporheic zone is an ecotone connecting the stream and groundwater ecosystem that plays a significant role for stream biogeochemistry. Water exchange across the stream-sediment interface and biogeochemical reactions in the streambed concur to affect ...

Remobilisation of fine sediment from chalk stream gravel beds under flushing flows: A flume experiment

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Through progressive flume experiments, this study demonstrated that increased bed shear stresses corresponded with increased cohesive fine sediment (<62‐μm) remobilisation depths from a representative chalk stream gravel bed. This represents some of the first scientifically robust data, which can direct revised and targeted fine sediment management in ...

Benthic and Hyporheic Macroinvertebrate Distribution Within the Heads and Tails of Riffles During Baseflow Conditions [PDF]

, 2016
The distribution of lotic fauna is widely acknowledged to be patchy reflecting the interaction between biotic and abiotic factors. In an in-situ field study, the distribution of benthic and hyporheic invertebrates in the heads (downwelling) and tails ...

A framework for in‐stream jams formed by snow avalanche‐delivered large wood

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Large wood delivered by avalanches organizes into blanket or transport jam complexes.Jam complexes increase channel width and promote pool and bar formation. Avalanche frequency and magnitude, which are dependent on hillslope angle and roughness characteristics, controls jam complex type.

Using Geophysical Observations of a Tracer Injection in a Riparian Aquifer to Explore How Bimodal Transport and Mixing Influences Nitrate Processing

Hydrological Processes, Volume 40, Issue 3, March 2026.
Our results embrace a simple conceptual model of preferential flow to illuminate the relationships among riparian groundwater nitrate concentration, flow dynamics, and substrate composition in stream corridors loaded with elevated nitrate from agricultural activities.

Silicon Isotopes Reveal a Non-glacial Source of Silicon to Crescent Stream, McMurdo Dry Valleys, Antarctica

Frontiers in Earth Science, 2020
In high latitude environments, silicon is supplied to river waters by both glacial and non-glacial chemical weathering. The signal of these two end-members is often obscured by biological uptake and/or groundwater input in the river catchment.

Effect of acidification on leaf litter decomposition in benthic and hyporheic zones of woodland streams [PDF]

, 2012
Anthropogenic acidification has deleterious effects on both structure and functioning of surface water ecosystems. This study examined how it may affect the leaf decomposition rate and the community structure and activity of decomposers in both benthic ...

Planning, Implementing, and Evaluating Stage 0 and Valley Bottom Restoration Projects: A Review With Lessons From the Grande Ronde Basin, USA

WIREs Water, Volume 13, Issue 2, March/April 2026.
Successful valley bottom restoration requires an understanding of current and historical conditions determining whether a reach can currently support a multi‐thread or meandering channel, an understanding of reference conditions to assist with design, clear objectives to evaluate design alternatives, and post‐project monitoring of success using a ...
