Vertical variation in diffusion coefficient within sediments [PDF]
River ecosystems can be strongly in uenced by contaminants in the water column, in the pore water and attached to sediment particles. Current models [TGD, 2003] predict exposure to sediments based on equilibrium partitioning between dissolved and ...

Hydrologic and geomorphic controls on hyporheic exchange during baseflow recession in a headwater mountain stream [PDF]
, 2012 [1] Hyporheic hydrodynamics are a control on stream ecosystems, yet we lack a thorough understanding of catchment controls on these flow paths, including valley constraint and hydraulic gradients in the valley bottom.

, 2020 The hyporheic zone (HZ) is a transition zone which connects rivers and aquifers. This area is a mixture of groundwater and surface water. Surface water moves into the surrounding alluvium and returns to the river again, and this movement of water is ...

, 2008 Water exchange between streams and groundwater (hyporheic exchange) facilitates exchange of heat, nutrients, toxics, and biota. In-stream geomorphic structures (IGSs) such as log dams and steps are common in natural streams and stream restoration ...

Toward a Universal Model of Hyporheic Exchange and Nutrient Cycling in Streams
AGU AdvancesTransformation and removal of dissolved nutrients and pollutants in streams strongly depends on microbial processes in streambed sediments. The contact between these solutes and microbial communities is mediated by the physical transport from the bulk stream to, and through, the streambed, a process broadly referred to as hyporheic exchange.

Hyporheic exchange processes in a coastal headwater stream
, 2007 Hyporheic exchange flow involves the two-way movement of water between the stream channel and the bed and banks. These exchange flows create distinctive habitats and influence biogeochemical processes and water temperatures.

Effects of Hyporheic Exchange and Settlement on the Particle Size Distribution of Colloids
Colloid particle size plays an important role in contaminant adsorption and clogging in the hyporheic zone, but it remains unclear how the particle size changes during the transport of colloids.

Hyporheic Exchange and Water Chemistry of Two Arctic Tundra Streams of Contrasting Geomorphology
, 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.

The influence of in-stream structures on temperature dynamics via induced hyporheic exchange
In-stream restoration structures, such as woody weirs, are intended to enhance hyporheic exchange, thus altering temperature dynamics in restored reaches. However, the relative effects of various in-stream structure types and streambed settings (i.e. the
