Delineating groundwater-surface water exchange flux using temperature-time series analysis methods [PDF]

, 2013
Groundwater-surface water interactions can play a crucial role in river-, riparian and wetland management. Their delineation and quantification at various spatial and temporal scales has become an important aspect in the study of contaminant transport ...

Hydrodynamics of Four Moments in the Life of a Floodplain Forest in Compound Channels

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Natural rivers often function as compound channels, comprising main channel and floodplain. Flow dynamics in these systems, particularly during floods, are influenced by factors such as vegetation, and flood intensity. Floodplain vegetation significantly modifies flow structures, affecting hydraulic conveyance and ecological functions.

Event‐Based Suspended Sediment Budgets Across a Gravel Bed River Network

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract This study explores the variability of suspended sediment transport down a river main stem by identifying sediment sources and in‐stream processes. It examines event‐scale suspended sediment budgets across a catchment with diverse sediment sources and assesses the influence of hydrological drivers such as spatial and temporal variability in ...

Enhancement of Hyporheic Flow and Solute Transport by Random Burrow‐ and Mound‐Induced Bioturbation

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Bioturbation significantly modifies sediment structure and surface roughness, thereby altering hyporheic exchange and associated biogeochemical processes. However, the role of random burrow galleries and mound arrangements in lotic environments remains unclear, particularly when considering field representative conditions.

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,

Evident Dependence of Dynamics of Baseflow on Groundwater Across the Contiguous United States

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Understanding baseflow dynamics is essential for sustainable ecosystem and water resource management. While most studies have documented climate‐baseflow relationships at regional scales, observational evidence of how groundwater influences baseflow dynamics across different spatiotemporal scales remains limited, substantially constraining ...

Effect of Surface Water Stage Fluctuation on Mixing‐Dependent Hyporheic Denitrification in Riverbed Dunes

Water Resources Research, 2019
The hyporheic zone, where surface water (SW) and groundwater (GW) interact in shallow sediments beneath rivers, is uniquely reactive and attenuates pollutants.

Compounding effect of meandering degree and vegetation density on hyporheic residence time in riparian zone

Shui kexue jinzhan, 2020
Hyporheic linkages between riparian zones and stream channels are a key component to riparian and stream system, which greatly influence the solutes transportation and transformation that are fundamental to sustaining biogeochemical cycling, biological ...

Fine sediment reduces vertical migrations of Gammarus pulex (Crustacea: Amphipoda) in response to surface water loss [PDF]

, 2015
Surface and subsurface sediments in river ecosystems are recognized as refuges that may promote invertebrate survival during disturbances such as floods and streambed drying.
