Reconceptualizing the hyporheic zone for nonperennial rivers and streams. [PDF]
Freshw Sci, 2022 Nonperennial streams dominate global river networks and are increasing in occurrence across space and time. When surface flow ceases or the surface water dries, flow or moisture can be retained in the subsurface sediments of the hyporheic zone, supporting aquatic communities and ecosystem processes.

Thermal Variations in the Hyporheic Zone of a Karst Stream [PDF]
International Journal of Speleology, 2006 This investigation quantifies how temperatures in the streambed sediments of a karst stream fluctuate in relation to discharge, seasonal, and diurnal temperature variations as the stream passes through a karst window.

Simultaneous attenuation of trace organics and change in organic matter composition in the hyporheic zone of urban streams [PDF]
Scientific Reports, 2021 Trace organic compounds (TrOCs) enter rivers with discharge of treated wastewater. These effluents can contain high loads of dissolved organic matter (DOM).

Occurence of microplastics in the hyporheic zone of rivers. [PDF]
Sci Rep, 2019 AbstractAlthough recent studies indicate that fluvial systems can be accumulation areas for microplastics (MPs), the common perception still treats rivers and streams primarily as pure transport vectors for MPs. In this study we investigate the occurrence of MPs in a yet unnoticed but essential compartment of fluvial ecosystems - the hyporheic zone (HZ)

Convergence of Groundwater Discharge through the Hyporheic Zone of Streams. [PDF]
Ground Water, 2023 Abstract Significant attention has been given to hyporheic water fluxes induced by hydromorphologic processes in streambeds and the effects they have on stream ecology. However, the impact of hyporheic fluxes on regional groundwater flow discharge zones as well as the interaction of these flows are much less investigated.

Influence of the In-Stream Structure on Solute Transport in the Hyporheic Zone. [PDF]
Int J Environ Res Public Health, 2022 The hyporheic zone (HZ) plays an important role in the river ecosystem, and hyporheic exchange and solute transport in the HZ are important ecological functions. However, the relationship between the design parameters of river structure and solute transport is still poorly understood.

Production of hydrogen peroxide in an intra-meander hyporheic zone at East River, Colorado [PDF]
Scientific Reports, 2022 The traditionally held assumption that photo-dependent processes are the predominant source of H2O2 in natural waters has been recently questioned by an increrasing body of evidence showing the ubiquitiousness of H2O2 in dark water bodies and in ...

Conserved environmental adaptations of stream microbiomes in the hyporheic zone across North America [PDF]
MicrobiomeBackground Stream hyporheic zones represent a unique ecosystem at the interface of stream water and surrounding sediments, characterized by high heterogeneity and accelerated biogeochemical activity.

Fragmentation of the Hyporheic Zone Due to Regional Groundwater Circulation
Water Resources Research, 2019 By use of numerical modeling and field observations, this work quantified the effects of catchment‐scale upwelling groundwater on the hyporheic (below stream) fluxes over a wide range of spatial scales.

Advance in field monitoring research of hydrodynamic process of hyporheic exchange in rivers
Shui kexue jinzhan, 2021 The hyporheic zone is the key transition region between rivers and aquifers, which is highly dynamic and sensitive. Frequent water exchange can trigger the bio-geochemical reactions within the hyporheic zone easily, and consequently make a difference to ...
