Impact of watershed topography on hyporheic exchange [PDF]
Among the interactions between surface water bodies and aquifers, hyporheic exchange has been recognized as a key process for nutrient cycling and contaminant transport.

Abstract River corridors are essential to life, but have been subjected to centuries of alteration, disconnection, and simplification. Process‐based river restoration has increased in recent years, with the goals of reversing degradation and reestablishing natural processes. Our objectives are twofold: (a) qualify the historic, ecologic, and geomorphic

Hyporheic zone size from 3D geophysics
The hyporheic zone is an ecologically critical region of a stream where surface waters transit the subsurface. Spatially defining the hyporheic zone from in-stream solute dynamics models is indirect, where individual model terms describe overlapping ...

Predicted Stream Temperatures Suggest Challenges for Pacific Salmon in Coming Decades
ABSTRACT Stream temperature is a key performance driver for aquatic species and a direct metric of climate impacts. We adapted a stream temperature model to predict daily temperatures across the Pacific Northwest USA through 2100. Our results suggested that stream temperatures may rise by ~1°C by the 2050's and 2°C by the 2080's, with seasonal and ...

Hyporheic rehabilitation in rivers: restoring vertical connectivity
1. The hyporheic zone below the channel and banks of many rivers where surface water and ground water exchanges plays a crucial functional role in the biogeochemical transformation of water, mediated by active microbial biofilms.

Investigation on temperature tracer method calculated flow rate of hyporheic layer in riparian zone
The hyporheic layer is an important part of riparian zones. To reveal the distribution of temperature and flow field of hyporheic layers in riparian zones under the influence of low temperature water, a real-time monitoring test of temperature and water ...

Hyporheic zone turnover time from 3D geophysics
A stream's balance of exchange with the hyporheic zone and the reaction rate within hyporheic flowpaths controls its nutrient removal capacity. However, our ability to quantify rates of exchange between surface and hyporheic waters is often limited to ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

River‐Floodplain Exchange Influences Basin‐Scale Mixing During Large Fluvial Flood Events
Abstract River‐floodplain exchange occurs when high flows inundate the floodplain and exchange water bi‐directionally between substrates and communities. While well‐understood locally, the full spatial heterogeneity of exchange event duration (the residence time) and magnitude (the exchange flux, or discharge) remains poorly constrained, limiting our ...

Sinuosity-driven hyporheic exchange in meandering rivers
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 ...
