Influence of nontrophic interactions between benthic invertebrates on river sediment processes: a microcosm study [PDF]

, 2004
The main objective of this study was to measure the impact of benthic invertebrate diversity on river sediment processes. We quantified the effects of interactions between three taxa (asellids, chironomid larvae, and tubificid worms).

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.

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 ...

Occurrence Characteristics of Inorganic Nitrogen in Groundwater in Silty-Clay Riparian Hyporheic Zones under Tidal Action: A Case Study of the Jingzi River in Shanghai, China

Applied Sciences, 2022
For comprehending the effect of tidal action on nitrogen cycle in silty-clay riparian hyporheic zones, the synchronous monitoring of water level and water quality was carried out along a test transect during a spring tidal period from 21 to 23 October ...

Dynamic Hyporheic Zones: Exploring the Role of Peak Flow Events on Bedform‐Induced Hyporheic Exchange [PDF]

Water Resources Research, 2019
AbstractDischarge varies in space and time, driving hyporheic exchange processes in river corridors that affect biogeochemical cycling and ultimately control the dynamics of biogeochemical hot spots and hot moments. Herein, we use a reduced‐order model to conduct the systematic analysis of the interplay between discharge variability (peak flow ...

Hydromorphological control of phosphorus in a large free-flowing gravel bed river: the Garonne river (France) [PDF]

, 2001
The objective of this paper is to relate phosphorus (P) transport dynamics and hydromorphological characteristics of a large human-influenced river, the River Garonne within a sector receiving the waste water of a sewage treatment plant for a population ...

Interactions between groundwater and surface water at river banks and the confluence of rivers [PDF]

, 2004
Riparian vegetation depends on hydrological resources and has to adapt to changes in water levels and soil moisture conditions. The origin and mixing of water in the streamside corridor were studied in detail.

Thermal Variations in the Hyporheic Zone of a Karst Stream [PDF]

International Journal of Speleology, 2006
This investigation quantifies how temperatures in the streambed sediments of a karst stream fluctuate in relation to discharge, seasonal, and diurnal temperature variations as the stream passes through a karst window.

Variability of Water Exchange in the Hyporheic Zone of a Lowland River in Poland Based on Gradientometric Studies

Quaestiones Geographicae, 2022
The Moszczenica is a lowland river, which is a third-order river with a length of 55 km; it flows into the Bzura River in central Poland. The objective of this study was to evaluate two important factors in the exchange between surface water and ...

Dissolved organic carbon uptake in streams: A review and assessment of reach‐scale measurements [PDF]

, 2016
Quantifying the role that freshwater ecosystems play in the global carbon cycle requires accurate measurement and scaling of dissolved organic carbon (DOC) removal in river networks.
