Particle size distribution of colloids affected by hyporheic exchange

, 2020
Colloids exist widely in rivers which can act as contaminants or carries of contaminants. Hyporheic exchange drives colloids to transport into the hyporheic zone. However, the variation of the particle size of colloids has seldom been considered in previous transport theories of colloids.

Toward a Universal Model of Hyporheic Exchange and Nutrient Cycling in Streams

AGU Advances
In this paper we demonstrate that several ubiquitous hyporheic exchange mechanisms can be represented simply as a one‐dimensional diffusion process, where the diffusivity decays exponentially with depth into the streambed. Based on a meta‐analysis of 106

Chemical Weathering and Mineralogy of McMurdo Dry Valley Streams: Examining the Controls of Current and Future Ephemeral Stream Geochemistry [PDF]

, 2015
The McMurdo Dry Valleys form the largest ice-free region in Antarctica and are the coldest, driest deserts in the world. But, for approximately 6-12 weeks per year in the austral summer, continuous sunlight and near-freezing temperatures create meltwater

The hyporheic zone and its functions: revision and research status in Neotropical regions

Brazilian Journal of Biology
The hyporheic zone (HZ), as the connecting ecotone between surface- and groundwater, is functionally part of both fluvial and groundwater ecosystems. Its hydrological, chemical, biological and metabolic features are specific of this zone, not belonging ...

A numerical study of the lateral hyporheic flow about a channels confluence

, 2016
Stream and pore waters continuously interact and mix within streambeds due to spatial and temporal variations in channel characteristics. This mixing is termed as hyporheic exchange and the zone where groundwater and stream water are mixing is called ...

Review: From multi-scale conceptualization to a classification system for inland groundwater-dependent ecosystems [PDF]

, 2017
Aquifers provide water, nutrients and energy with various patterns for many aquatic and terrestrial ecosystems. Groundwater-dependent ecosystems (GDEs) are increasingly recognized for their ecological and socio-economic values.

Seasonality Controls Biogeochemical Shifts in Oxygen, Carbon, and Nitrogen Along a 12‐m, 54 hr‐Long Hyporheic Flowpath

Water Resources Research
Hyporheic exchange is critical to river corridor biogeochemistry, but decameter‐scale flowpaths (∼10‐m long) are understudied due to logistical challenges (e.g., sampling at depth, multi‐day transit times).
