Spatial and temporal variability of hyporheic invertebrate community within a stream reach of the River Bača (W Slovenia)

Natura Sloveniae, 2011
We studied spatio-temporal distribution of hyporheic invertebrate community at the stream-reach scale in the River Bača on three sampling occasions (January, March, May) in 2005.

Short-term influences of flow alteration on microbial community structure and putative metabolic functions in gravel bar hyporheic zones

Frontiers in Environmental Science, 2023
Microbial communities in the hyporheic zone are important for self-purification as the riverbed is metabolically active and responsible for the retention, storage, and mineralisation of organic matter transported in the surface water.

Drivers of Functional Diversity in the Hyporheic Zone of a Large River

SSRN Electronic Journal, 2022
The effects of regional (hydrogeology and geomorphology) and local (sediment and hydrology) characteristics on hyporheic assemblages were studied along a 40-km reach of a large gravel-bed river. Hyporheic water and fauna were sampled at the upstream and downstream positions of 15 large gravel bars.

Evaluation of Nitrate Reduction Potential Using Field Water Quality Parameters of the Hyporheic Zone in the Tandoncheon Stream, Daejeon, Korea [PDF]

Geo Data
The hyporheic zone is a transitional interface between surface water and groundwater that is characterized by distinct physicochemical conditions and plays a key role in various biogeochemical processes.

Silicon Isotopes Reveal a Non-glacial Source of Silicon to Crescent Stream, McMurdo Dry Valleys, Antarctica

Frontiers in Earth Science, 2020
In high latitude environments, silicon is supplied to river waters by both glacial and non-glacial chemical weathering. The signal of these two end-members is often obscured by biological uptake and/or groundwater input in the river catchment.

Influence of the hyporheic zone on the phosphorus dynamics of a large gravel-bed river, Garonne River, France [PDF]

, 2009
Phosphorus (P) concentrations in sediments and in surface and interstitial water from three gravel bars in a large river (Garonne River, southern France) were measured daily, downstream of a wastewater treatment plant for a city of 740 000 inhabitants ...

Logjam Characteristics as Drivers of Transient Storage in Headwater Streams

Water Resources Research, 2023
Logjams in a stream create backwater conditions and locally force water to flow through the streambed, creating zones of transient storage within the surface and subsurface of a stream.

Low flow controls on benthic and hyporheic macroinvertebrate assemblages during supra-seasonal drought [PDF]

, 2009
Despite the widely accepted importance of the hyporheic zone as a habitat for stream macroinvertebrates during floods, few data exist regarding community composition and distribution during periods of low flow or drought in perennial streamsi ...

Hyporheic hydraulic geometry: Conceptualizing relationships among hyporheic exchange, storage, and water age.

PLoS ONE, 2022
Hyporheic exchange is now widely acknowledged as a key driver of ecosystem processes in many streams. Yet stream ecologists have been slow to adopt nuanced hydrologic frameworks developed and applied by engineers and hydrologists to describe the ...

Maximum respiration rates in hyporheic zone sediments are primarily constrained by organic carbon concentration and secondarily by organic matter chemistry [PDF]

Biogeosciences, 2023
River corridors are fundamental components of the Earth system, and their biogeochemistry can be heavily influenced by processes in subsurface zones immediately below the riverbed, referred to as the hyporheic zone.
