Despite the recognition of floodplain importance in the scientific community, floodplains are
not afforded the same legal protection as river channels. In the United States alone, flood …

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 …

Microorganisms in wetland groundwater play an essential role in driving global
biogeochemical cycles. However, largely due to the dynamics of spatiotemporal surface …

Riparian zones can receive large amounts of nitrate, potentially contributing to water
pollution. Denitrification is a major pathway to remove nitrate. Previous research on riparian …

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 …

Riparian sediment is the last barrier preventing contaminants from polluting aquatic
ecosystems. Recently, microplastics (MPs) have frequently been found in sediments …

The Earth is experiencing excessive nitrogen (N) input to its various ecosystems due to
human activities. How to effectively and efficiently remove N from ecosystems has been, is …

Identifying groundwater (GW)–surface water (SW) interactions in riparian zones is important
for assessing the transport pathways of pollutants and all potential biochemical processes …

With the rapid development of society, the soil and water environments in many countries
are suffering from severe pollution. Pollutants in different phases will eventually gather into …

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 …
