Is the Hyporheic Zone Relevant beyond the Scientific Community? [PDF]
Water, 2019 Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river network. We elaborate on the main physical, biological,

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.

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)

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 ...

Aquatic hyphomycete species are screened by the hyporheic zone of woodland streams. [PDF]
Appl Environ Microbiol, 2014 Aquatic hyphomycetes strongly contribute to organic matter dynamics in streams, but their abilities to colonize leaf litter buried in streambed sediments remain unexplored.

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.

Nitrogen circulation in a Mediterranean holm oak forest, La Castanya, Montseny, northeastern Spain [PDF]
Hydrology and Earth System Sciences, 2002 The importance of storm frequency as well as the groundwater and hyporheic inputs on nitrate (NO3-N) and ammonium (NH4-N) levels in stream water were studied in a small perennial Mediterranean catchment, Riera Major, in northeast Spain.

How daily groundwater table drawdown affects the diel rhythm of hyporheic exchange [PDF]
Hydrology and Earth System Sciences, 2021 Groundwater table dynamics extensively modify the volume of the hyporheic zone and the rate of hyporheic exchange processes. Understanding the effects of daily groundwater table fluctuations on the tightly coupled flow and heat transport within hyporheic

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 ...
