Redox-driven biogeochemical element cycles play a central role in converting organic
matter in aquatic ecosystems. They also perform key functions such as removing nitrate …

Floodplains perform diverse functions, including attenuation of fluxes of water, solutes, and
particulate material. Critical details of floodplain storage including magnitude, duration, and …

It has been documented that contaminants could be degraded by hydroxyl radicals (• OH)
produced upon oxygenation of Fe (II)-bearing sediments. However, the dependence of …

Core Ideas Development of a 300‐km2 mountainous headwater testbed began in 2016 in
the East River. The testbed can be used to explore how watershed changes impact …

Reduction–oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like
most soil properties and processes, redox is spatiotemporally heterogeneous. However …

Reductive transformation of organic contaminants by FeS in anoxic environments has been
documented previously, whereas the transformation in oxic environments remains poorly …

Ecological water replenishment (EWR) is an essential approach for improving the quantity
and quality of regional water. The Chaobai River is a major river in Beijing that is …

We use 3‐D high‐resolution reactive transport modeling to investigate whether the spatial
distribution of organic‐carbon‐rich and chemically reduced sediments located in the riparian …

Abstract The Qinghai-Tibet Plateau (QTP) is the source for many of the most important rivers
in Asia. It is also an essential ecological barrier in China and has the characteristic of …

To understand how redox processes influence carbon, nitrogen, and iron cycling within the
intrameander hyporheic zone, we developed a biotic and abiotic reaction network and …
