Impact of watershed topography on hyporheic exchange [PDF]

Advances in Water Resources, 2016
Abstract Among the interactions between surface water bodies and aquifers, hyporheic exchange has been recognized as a key process for nutrient cycling and contaminant transport. Even though hyporheic exchange is strongly controlled by groundwater discharge, our understanding of the impact of the regional groundwater flow on hyporheic fluxes is still

Effects of Benthic Burrows on Hyporheic Exchange

Water Resources Research
AbstractMacrobenthic invertebrates are widely distributed on sediments, and the micro‐morphology such as burrows and sand mounds due to their bioturbation activities can cause substantial changes in hyporheic exchange (HE). This study explores the characteristics of HE induced by benthic burrows through flume experiments and numerical simulations ...

Sinuosity‐driven hyporheic exchange in meandering rivers

Geophysical Research Letters, 2006
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 planimetry. The hyporheic fluxes induced at the meander scale by the river sinuosity can therefore be

Hydraulic controls of in‐stream gravel bar hyporheic exchange and reactions [PDF]

Water Resources Research, 2015
AbstractHyporheic exchange transports solutes into the subsurface where they can undergo biogeochemical transformations, affecting fluvial water quality and ecology. A three‐dimensional numerical model of a natural in‐stream gravel bar (20 m × 6 m) is presented. Multiple steady state streamflow is simulated with a computational fluid dynamics code that

Differential microplastic storage in main channel and backwater sediments of the Kaskaskia River (Illinois, United States) [PDF]

Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract Rivers are major pathways for microplastic transport, yet controls on microplastic storage across different riverine environments remain poorly constrained, particularly in managed systems. Here, we quantify microplastic abundance and characteristics in water and sediments from the Kaskaskia River (Illinois), a regulated tributary of the ...

Effect of Combined Subsurface Structures and Steps on Hyporheic Exchange [PDF]

, 2023
The deployment of artificial structures in streambeds has been proposed as a way to enhance hyporheic exchange, and numerical models can be used to quantify their effects.

Imaging hyporheic exchange [PDF]

Eos, Transactions American Geophysical Union, 2012
The dynamics of flow through the subterranean area at the base and along the sides of streambeds, known as the hyporheic zone, affect stream ecosystem dynamics, but researchers do not have a solid understanding of what controls the amount of hyporheic exchange.Ward et al. injected tracers into a stream in the H.J.

Impact of hyporheic zones on nutrient dynamics [PDF]

, 2013
Riverine sediments play a fundamental role within the fluvial system, since they represent potential removal zones of stream-borne pollutants and, in particular, nutrients derived by anthropogenic activities.
