Deposition process and mechanism of colloidal particles in hyporheic zone

open access: yesShui kexue jinzhan, 2021
The hyporheic zone is a region where surface and subsurface water mix in rivers. It is an important area for the exchange of mass and energy and an essential habitat for aquatic organisms.

Study of heterogeneous vertical hyporheic flux via streambed temperature at different depths [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2015
The hyporheic flux can be characterized using the heat-tracing method. Based on the analytical solution of the one-dimensional steady-state heat transport equation under vertical groundwater discharge conditions, hyporheic flux was obtained via a curve ...

Coupled Biotic-Abiotic Processes Control Biogeochemical Cycling of Dissolved Organic Matter in the Columbia River Hyporheic Zone

open access: yesFrontiers in Water, 2021
A critical component of assessing the impacts of climate change on watershed ecosystems involves understanding the role that dissolved organic matter (DOM) plays in driving whole ecosystem metabolism.

Revealing the influence of hyporheic water exchange on the composition and abundance of bottom-dwelling macroinvertebrates in a temperate lowland river

open access: yesKnowledge and Management of Aquatic Ecosystems, 2021
We studied distributions and abundances of macroinvertebrates in relation to hyporheic water exchange (HWE) patterns of the upper Biebrza − a small, lowland, low dynamic European river located in Northeast Poland.

Quantifying Small-Scale Hyporheic Streamlines and Resident Time under Gravel-Sand Streambed Using a Coupled HEC-RAS and MIN3P Model

open access: yesEng, 2022
Distribution of the water flow path and residence time (HRT) in the hyporheic zone is a pivotal aspect in anatomizing the transport of environmental contaminants and the metabolic rates at the groundwater and surface water interface in fluvial habitats ...

Hyporheic flow in aquatic Ranunculus habitats in temperate lowland rivers in Central Europe

open access: yesEcological Indicators, 2023
The study attempted to assess the influence of the filtration stream and hydraulic gradient in the hyporheic zone on the distribution of water crowfoot (Ranunculus sect.

Influence of Oscillating Flow on Hyporheic Zone Development [PDF]

open access: yesGroundwater, 2011
The hyporheic zone is an ecologically important ecotone that describes the extent to which nutrient‐rich surface waters penetrate the shallow subsurface adjacent to a flowing surface water body. Although steady‐state models satisfactorily explain the incursion of surface water into the subsurface as a function of head gradients developed across ...

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]

open access: yes, 2011
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Groundwater–Stream Connectivity Mediates Metal(loid) Geochemistry in the Hyporheic Zone of Streams Impacted by Historic Mining and Acid Rock Drainage

open access: yesFrontiers in Water, 2020
High concentrations of trace metal(loid)s exported from abandoned mine wastes and acid rock drainage pose a risk to the health of aquatic ecosystems.

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

open access: yes, 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 ...
