Vertical hydraulic gradient research in hyporheic zone of Beberibe river in Pernambuco State (Brazil)

RBRH
The interaction between groundwater and surface water occurs naturally and is dependent on the dynamics in the hyporheic zone. The hyporheic zone is the interface between the surface water source and the phreatic aquifer and it’s a system that also ...

Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers [PDF]

, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed

Gene‐Informed Modeling of Denitrification Process in Groundwater Through Dynamic Flux Balance Analysis and Deep Learning

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract We introduce two gene‐informed approaches that, for the first time, explicitly incorporate microbial genomic information into groundwater denitrification simulations. First, we couple the dynamic flux balance analysis (DFBA, which resolves genome‐resolved metabolic networks) with the PFLOTRAN reactive transport model (RTM).

Hyporheic Exchange and Water Chemistry of Two Arctic Tundra Streams of Contrasting Geomorphology [PDF]

, 2008
The North Slope of Alaska’s Brooks Range is underlain by continuous permafrost, but an active layer of thawed sediments develops at the tundra surface and beneath streambeds during the summer, facilitating hyporheic exchange.

Tracing Seasonal Ground Thaw with Stream Chemistry in Alaskan Arctic Permafrost Catchments

Hydrological Processes, Volume 40, Issue 4, April 2026.
In permafrost regions, thaw dynamics influence hydrological and biogeochemical processes, yet these dynamics are difficult to observe at catchment scales. We tested nine solutes as tracers of thaw depth across three Arctic catchments. Five solutes were effective tracers in at least one catchment with differences due to varying landscape characteristics.

A Novel Drive‐Point Multilevel System to Investigate PFAS and Other Contaminants of Global Concern in the Hyporheic Zone of a Wastewater Effluent Dominated Stream

Hydrological Processes, Volume 40, Issue 4, April 2026.
This study tested the applicability of a novel drive‐point multilevel system (DP‐MLS) for measuring head profiles and characterizing contaminant concentrations in the hyporheic zone of a well‐studied temperate region effluent dominated stream (EDS).

Unraveling Functional Diversity Patterns in Hyporheic Zones: A Trait-Based Approach Applied to Copepods from the Rio Gamberale Creek

Diversity
Despite the recognized ecological significance of hyporheic zones, biological investigations into their ecology, especially concerning functional diversity, remain limited.

Quantifying the impact of the stream-aquifer interaction on the surface-subsurface exchange [PDF]

, 2008
The exchange of oxygen and nutrients between the well-aerated stream water and the subsurface water is crucial for the biochemical conditions of the hyporheic zone, i.e., the interface region between the stream and the deep aquifer. The hyporheic zone is

The macroinvertebrate seedbank promotes community persistence in temporary rivers across climate zones [PDF]

, 2013
1. Aquatic macroinvertebrates inhabiting temporary rivers are typically described as having low resistance to riverbed drying. However, little research has examined the ‘seedbank’ within dry riverbed sediments, which comprises aquatic life stages that ...

Hydrology regulates sources and sinks of carbon dioxide and methane in a tropical headwater stream

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Tropical headwater streams are potentially important sources of greenhouse gases, with seasonal shifts in flow regimes and hydrological connectivity likely influencing their sources and sinks of greenhouse gases. We developed a mass balance for carbon dioxide (CO2) and methane (CH4) over a year in a well‐instrumented headwater stream in the ...
