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.

Metabolism Modeling in Rivers With Unsteady Flow Conditions and Transient Storage Zones

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 3, March 2023., 2023
Abstract Whole‐stream metabolism characterizes energy and carbon transformations, thus providing an estimate of the food base and CO2 emission sources from streams and rivers. Metabolism models are generally implemented with a steady flow assumption that does not hold true for many systems with sub‐daily flow variation, such as river sections ...

Quantifying the ecological effects of water abstraction in Alpine streams through flume simulations

Ecohydrology, Volume 15, Issue 6, September 2022., 2022
Abstract Water abstraction by small hydropower plants is a growing human pressure on Alpine stream ecosystems. Using a set of seminatural streamside flumes, we investigated the response of benthic invertebrate communities to a 50% experimental reduction of the natural discharge.

The hyporheic zone as an invertebrate refuge during a fine sediment disturbance event

Ecohydrology, Volume 15, Issue 6, September 2022., 2022
Abstract Subsurface sediments offer an important refuge that support the survival and persistence of river invertebrates during adverse surface conditions. Access to refuges for invertebrates varies with differing hydrological and substrate characteristics, especially the proportion of fine sediment.

The role of organisms in hyporheic processes : gaps in current knowledge, needs for future research and applications [PDF]

, 2012
Fifty years after the hyporheic zone was first defined (Orghidan, 1959), there are still gaps in the knowledge regarding the role of biodiversity in hyporheic processes.

Organizational Principles of Hyporheic Exchange Flow and Biogeochemical Cycling in River Networks Across Scales

Water Resources Research, Volume 58, Issue 3, March 2022., 2022
Abstract Hyporheic zones increase freshwater ecosystem resilience to hydrological extremes and global environmental change. However, current conceptualizations of hyporheic exchange, residence time distributions, and the associated biogeochemical cycling in streambed sediments do not always accurately explain the hydrological and biogeochemical ...

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,

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

, 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 ...

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.

Benthic and Hyporheic Macroinvertebrate Distribution Within the Heads and Tails of Riffles During Baseflow Conditions [PDF]

, 2016
The distribution of lotic fauna is widely acknowledged to be patchy reflecting the interaction between biotic and abiotic factors. In an in-situ field study, the distribution of benthic and hyporheic invertebrates in the heads (downwelling) and tails ...
