River‐Floodplain Exchange Influences Basin‐Scale Mixing During Large Fluvial Flood Events

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract River‐floodplain exchange occurs when high flows inundate the floodplain and exchange water bi‐directionally between substrates and communities. While well‐understood locally, the full spatial heterogeneity of exchange event duration (the residence time) and magnitude (the exchange flux, or discharge) remains poorly constrained, limiting our ...

Sensitivity of Simulated Hyporheic Exchange to River Bathymetry: The Steinlach River Test Site

, 2019
This study determines the aspects of river bathymetry that have the greatest influence on the predictive biases when simulating hyporheic exchange. To investigate this, we build a highly parameterized HydroGeoSphere model of the Steinlach River Test Site

Hyporheic exchange of solutes and colloids with moving bed forms [PDF]

Water Resources Research, 2001
Stream‐subsurface exchange provides the opportunity for stream‐borne substances to interact with streambed sediments in the subsurface hyporheic mixing zone. The downstream transport of both solutes and colloids can be substantially affected by this exchange, with significant implications for contaminant transport and stream ecology.

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 ...

Gene‐Informed Modeling of Denitrification Process in Groundwater Through Dynamic Flux Balance Analysis and Deep Learning

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract We introduce two gene‐informed approaches that, for the first time, explicitly incorporate microbial genomic information into groundwater denitrification simulations. First, we couple the dynamic flux balance analysis (DFBA, which resolves genome‐resolved metabolic networks) with the PFLOTRAN reactive transport model (RTM).

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.

Toward a conceptual framework of hyporheic exchange across spatial scales [PDF]

, 2018
Rivers are not isolated systems but interact continuously with groundwater from their confined headwaters to their wide lowland floodplains. In the last few decades, research on the hyporheic zone (HZ) has increased appreciation of the hydrological ...

Flipping the thin film model: Mass transfer by hyporheic exchange in gaining and losing streams [PDF]

, 2016
The exchange of mass between a stream and its hyporheic zone, or “hyporheic exchange,” is central to many important ecosystem services. In this paper we show that mass transfer across the streambed by linear mechanisms of hyporheic exchange in a gaining ...

Quantifying multi-scale advective hyporheic exchange through mass transfer [PDF]

, 2015
Mixing between water from free surface flow and subsurface pore-water in the sediment bed is known as hyporheic exchange. At local scales, flushing through porous sediments purifies streamborne water and biogeochemical cycling of oxygen and nutrients ...
