Probabilistic Forecasting of Nitrogen Dynamics in Hyporheic Zone [PDF]

Water Resources Research, 2018
AbstractNitrification‐denitrification processes in the hyporheic zone control the dynamics of dissolved inorganic nitrogen (DIN) species and can lead to production of nitrous oxide, which contributes to the greenhouse effect. We consider DIN dynamics in an advection‐dominated regime, wherein transport and reactions occur along streamlines crossing ...

Faunal response to benthic and hyporheic sedimentation varies with direction of vertical hydrological exchange [PDF]

, 2014
1. Sedimentation and clogging of benthic and hyporheic zone substrates is increasingly being recognised as one of the greatest threats to the ecological integrity of riverine ecosystems globally. This ex-situ study examined the influence of sedimentation

The hyporheic zone as an invertebrate refuge: a review of variability in space, time, taxa and behaviour [PDF]

, 2012
The hyporheic zone is a potential refuge that can promote persistence of benthic invertebrates during adverse conditions in surface streams. For decades, changes in invertebrate depth distribution have been investigated in relation to flood, low flow and

Advances in the response of surface-subsurface water exchange to activities of typical aquatic organisms in the hyporheic zone of rivers

Shui kexue jinzhan, 2022
The river hyporheic zone is the main area of surface-subsurface connection and exchange. Surface-subsurface water exchange promotes the transport and transformation of biogenic substances and can conserve water resources, stabilize regional ecological ...

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 ...

Dynamic processes and ecological restoration of hyporheic layer in riparian zone

Shui kexue jinzhan, 2013
Hyporheic layer of riparian zone is an active transition zone and ecotone between river and groundwater in riparian zone,which can be denoted respectively from hydrogeography,ecology and environment.Due to its unique structure properties in vertical ...

Hyporheic invertebrate assemblages at reach scale in a Neotropical stream in Brazil

Brazilian Journal of Biology
In the Neotropical Region, information concerning hyporheic communities is virtually non-existent. We carried out a sampling survey in the hyporheic zone of the Tijuca River, in the Tijuca National Park, located in the urban area of the city of Rio de ...

Drivers and spatio-temporal extent of hyporheic patch variation: implications for sampling. [PDF]

PLoS ONE, 2012
The hyporheic zone in stream ecosystems is a heterogeneous key habitat for species across many taxa. Consequently, it attracts high attention among freshwater scientists, but generally applicable guidelines on sampling strategies are lacking.

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

, 2010
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 ...

Nitrate removal in a restored riparian groundwater system : functioning and importance of individual riparian zones [PDF]

, 2012
For the design and the assessment of river restoration projects, it is important to know to what extent the elimination of reactive nitrogen (N) can be improved in the riparian groundwater.
