Is the Hyporheic Zone Relevant beyond the Scientific Community? [PDF]

, 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,

Sinuosity‐driven hyporheic exchange in meandering rivers

Geophysical Research Letters, 2006
A model for the evaluation of the intra‐meander hyporheic exchange fluxes is presented. The method relies on a physically‐based morphodynamic model to predict the characteristics of the flow field in a meandering river and the temporal evolution of its planimetry. The hyporheic fluxes induced at the meander scale by the river sinuosity can therefore be

Gravity‐driven water exchange between streams and hyporheic zones [PDF]

Geophysical Research Letters, 2009
The exchange of water and nutrients between rivers and hyporheic zones has been recognized as a very important process for the stream ecosystem. This water exchange is generally explained by pressure gradients on the riverbed that are induced by fluvial geomorphological features or by turbulent coherent structures.

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 ...

Toward a conceptual framework of hyporheic exchange across spatial scales [PDF]

Hydrology and Earth System Sciences, 2018
Rivers are not isolated systems but interact continuously with groundwater from their confined headwaters to their wide lowland floodplains. In the last few decades, research on the hyporheic zone (HZ) has increased appreciation of the hydrological ...

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 ...

Hyporheic Oxygen Dynamics in the East River, Colorado: Insights From an In‐Situ, High Frequency Time Series During Two Distinct Flow Seasons

Water Resources Research, 2023
Dissolved oxygen (DO) is critical for aquatic ecosystems, however, few studies have focused on the long‐term DO dynamics in hyporheic zones, which are a function of both transport (hydrologic exchange between river and hyporheic zone) and uptake by ...

Spatial distribution of the water exchange through river cross-section – measurements and the numerical model [PDF]

Archives of Environmental Protection, 2021
The aspects of surface stability and groundwater exchange recognized by many researchers due to the intensification of agriculture and industry (manifested in, e.g., regulation and dredging of riverbed sediments of rivers) are now widely discussed on the

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).
