Rivers and river habitats around the world are under sustained pressure from human
activities and the changing global environment. Our ability to quantify and manage the river …

The hyporheic zone, where surface water and groundwater mix, is an important microbial
habitat where biogeochemical reactions influence water quality. We show that spatial …

In many aquifers around the world, there exists the issue of abnormal concentrations of Fe
and Mn in groundwater. Although it has been recognized that the main source of this issue is …

Dissolved oxygen (DO) is critical for aquatic ecosystems, however, few studies have focused
on the long‐term DO dynamics in hyporheic zones, which are a function of both transport …

Hyporheic exchange influences water quality and controls numerous physical, chemical,
and biological processes. Despite its importance, hyporheic exchange and the associated …

Coupled abiotic and biotic processes in the hyporheic zone, where surface water and
groundwater mix, play a critical role in the biogeochemical cycling of carbon, nutrients, and …

High concentrations of trace metal (loid) s exported from abandoned mine wastes and acid
rock drainage pose a risk to the health of aquatic ecosystems. To determine if and when the …

We develop a new framework, hyporheic reaction potential (HRP), to predict the influence of
oxidation-reduction reactions on metal fate and transport in streams using data from tracer …

Transverse hyporheic transport and biogeochemical reactions in a compound channel
remain poorly understood. As floodplains are submerged, solutes in the surface water enter …

An increasing number of studies have combined saline tracer injections with time-lapse
electrical resistivity (ER) surveys to explore solute exchange within the hyporheic zone. The …
