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

Eng, 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

Ecological 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 water level change on the geochemical dynamics of the lateral hyporheic zone between river water and groundwater

Shui kexue jinzhan, 2017
Water level of the hyporheic zone essentially varies in different hydrological periods. In order to investigate the geochemical characteristics of the lateral hyporheic zone in different hydrological periods, Maanxi Creek in Chongqing was selected to be ...

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

, 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.

Longitudinal transformation of nitrogen and carbon in the hyporheic zone of an N-rich stream: A combined modelling and field study [PDF]

, 2011
A combined modelling and field study approach was used to examine biogeochemical functioning of the hyporheic zone in two gravel bars in an N-rich fourth-order stream (River Hers, south-west France).

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

Frontiers 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.

Changes in invertebrate assemblage composition in benthic and hyporheic zones during a severe supraseasonal drought [PDF]

, 2014
Droughts are unpredictable disturbances characterized in streams by declining flow, reduced habitat availability, and deteriorating abiotic conditions.

Influence of Oscillating Flow on Hyporheic Zone Development [PDF]

Groundwater, 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 ...

Artificial flood reduces fine sediment clogging enhancing hyporheic zone physicochemistry and accessibility for macroinvertebrates

Ecological Solutions and Evidence, 2021
River regulation globally has reduced the riverine connectivity (longitudinal, lateral and vertically) with significant consequences for their abiotic and biotic components.

Hyporheic invertebrates as bioindicators of ecological health in temporary rivers: a meta-analysis [PDF]

, 2013
Worldwide, many rivers cease flow and dry either naturally or owing to human activities such as water extraction. However, even when surface water is absent, diverse assemblages of aquatic invertebrates inhabit the saturated sediments below the river bed
