Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

River Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

A mathematical approach to improving the representation of surface water–groundwater exchange in the hyporheic zone

Journal of Water and Climate Change, 2021
It is well known that land surface topography governs surface–groundwater interactions under some circumstances and can be separated in a Fourier-series spectrum that provides an exact analytical solution of both the surface and the underlying three ...

Temporal responses of groundwater-surface water exchange to successive storm events [PDF]

, 2015
Groundwater-surface water exchange within the hyporheic zone is widely recognized as a key mechanism controlling the fate of nutrients within catchments.

Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...

The Fragility of Bedform‐Induced Hyporheic Zones: Exploring Impacts of Dynamic Groundwater Table Fluctuations

Water Resources Research
Hyporheic zones are commonly regarded as resilient and enduring interfaces between groundwater and surface water in river corridors. In particular, bedform‐induced advective pumping hyporheic exchange (bedform‐induced exchange) is often perceived as a ...

A Novel Drive‐Point Multilevel System to Investigate PFAS and Other Contaminants of Global Concern in the Hyporheic Zone of a Wastewater Effluent Dominated Stream

Hydrological Processes, Volume 40, Issue 4, April 2026.
This study tested the applicability of a novel drive‐point multilevel system (DP‐MLS) for measuring head profiles and characterizing contaminant concentrations in the hyporheic zone of a well‐studied temperate region effluent dominated stream (EDS).

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.

Quantifying the impact of the stream-aquifer interaction on the surface-subsurface exchange [PDF]

, 2008
The exchange of oxygen and nutrients between the well-aerated stream water and the subsurface water is crucial for the biochemical conditions of the hyporheic zone, i.e., the interface region between the stream and the deep aquifer. The hyporheic zone is

Controls on spatial and temporal variations in sand delivery to salmonid spawning riffles [PDF]

, 2017
Fine sediment infiltration into gravel interstices is known to be detrimental to incubating salmonid embryos. Infiltration into spawning riffles can show large spatial variations at the scale of a morphological unit and over time, with significant ...
