Intra‐meander hyporheic flow in alluvial rivers

open access: yesWater Resources Research, 2008
Several geomorphological fluvial features are able to induce hyporheic exchange between the rivers and the alluvial sediments. However, while the small‐scale exchange induced by bed forms has been thoroughly investigated, the role of the larger features remains poorly understood.

Thermal Variations in the Hyporheic Zone of a Karst Stream [PDF]

open access: yesInternational 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.

Pilliga Ghosts: The Novel Fungi of the Rivers, Creeks, Lakes, and Dams of the Narrabri Region, Australia. [PDF]

open access: yesEnviron Microbiol Rep
Freshwater systems of the semi‐arid Narrabri region, Australia, are hotspots of novel fungal and eukaryote diversity, dominated by zoosporic fungi and unclassified lineages. ITS‑based DNA and water chemistry analyses across various water bodies revealed strong seasonal patterns, a scarcity of aquatic hyphomycetes that may reflect environmental ...

Spatiotemporal Variability of Hyporheic Flow in a Losing River Section [PDF]

open access: yesWater Resources Research
Characterizing the spatiotemporal variability of water fluxes at the stream‐groundwater interface is extremely challenging due to the lack of methods for estimating hyporheic flows at different scales.

Occurence of microplastics in the hyporheic zone of rivers [PDF]

open access: yesScientific Reports, 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)

Advancement in the hyporheic exchange in rivers

open access: yes, 2008
Surface-subsurface exchange (hyporheic exchange) across the river bed plays an important role in the fate of solutes and contaminants in rivers. The main mechanisms of hyporheic exchange include pumping exchange and turnover exchange. The pumping exchange is driven by pore water flows induced by head gradients.

Convergence of Groundwater Discharge through the Hyporheic Zone of Streams. [PDF]

open access: yesGround Water, 2023
Significant attention has been given to hyporheic water fluxes induced by hydromorphologic processes in streambeds and the effects they have on stream ecology.

Spatial variability in the hyporheic zone refugium of temporary streams [PDF]

open access: yes, 2011
A key ecological role hypothesized for the hyporheic zone is as a refugium that promotes survival of benthic invertebrates during adverse conditions in the surface stream.

Hyporheic Source and Sink of Nitrous Oxide [PDF]

open access: yesWater Resources Research, 2018
AbstractNitrous oxide (N2O) is a potent greenhouse gas with an estimated 10% of anthropogenic N2O coming from the hyporheic zone of streams and rivers. However, difficulty in making accurate fine‐scale field measurements has prevented detailed understanding of the processes of N2O production and emission at the bedform and flowline scales.
