The Influences of a Clay Lens on the Hyporheic Exchange in a Sand Dune

, 2018
A laboratory flume simulating a riverbed sand dune containing a low-permeability clay lens was constructed to investigate its influence on the quality and quantity of hyporheic exchange.

Geomorphic controls on hyporheic exchange flow in mountain streams

Simulations of stream-subsurface water exchange (hyporheic exchange) using a three-dimensional steady state groundwater flow model and a particle tracking model in unconstrained and constrained reaches of small (2nd-order) and intermediate (5th-order ...

Assessment of Hyporheic Exchange at In-stream Restoration Structures on Savage River, Garrett County, Maryland

, 2013
Previous studies have shown that in-stream restoration structures alter hyporheic exchange dynamics in restored channels; this study assessed hyporheic exchange at a recently constructed stream reach, including the effects of in-stream restoration ...

An Analysis of the Factors Affecting Hyporheic Exchange based on Numerical Modeling

, 2019
The hyporheic zone is a transition zone for the exchange of matter and energy between surface water and subsurface water. The study of trends and sensitivities of bed hyporheic exchanges to the various influencing factors is of great significance.

Impact of Dynamically Changing Discharge on Hyporheic Exchange Processes Under Gaining and Losing Groundwater Conditions

, 2018
Channel discharge, geomorphological setting, and regional groundwater flow determine the spatiotemporal variability of bedform‐induced hyporheic exchange and the emergence of biogeochemical hot spots and hot moments that it drives. Of particular interest,

Hyporheic zone turnover time from 3D geophysics

, 2019
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 ...

Bedform-induced hyporheic exchange: impact of porous medium permeability

, 2014
Stream and pore waters continuously interact and mix within streambeds due to spatial and temporal variations in channel characteristics. This mixing is termed hyporheic exchange and the zone where groundwater and stream water are mixing is called the ...
