High-frequency water quality measurements in streams and rivers have expanded in scope
and sophistication during the last two decades. Existing technology allows in situ automated …

Processes that drive variability in catchment solute sourcing, transformation, and transport
can be investigated using concentration–discharge (C–Q) relationships. These relationships …

Due to the increased availability of high-frequency measurements of stream chemistry
provided by in situ sensors, researchers have gained more access to relationships between …

The profound influence of climate change on the hydrological cycle raises concerns about
its potential impacts on water quality, particularly in agricultural catchments. Here, we …

Runoff events play an important role in nitrate export from catchments, but the variability of
export patterns between events and catchments is high and the dominant drivers remain …

Understanding the physics of nitrate contamination in surface and subsurface water is vital
for mitigating downstream water quality impairment. Though high frequency sensor data …

Trends and ecological consequences of phosphorus (P) decline and increasing nitrogen (N)
to phosphorus (N: P) ratios in rivers and estuaries are reviewed and discussed. Results …

Agriculturally-driven land use change and hydrologic modifications have influenced solute
transport in midwestern US streams. A clear understanding of the mechanisms driving …

Over recent decades, increased agricultural activities have significantly modified nitrogen
(N) and water cycles, leading to a worsening of the environmental quality and widespread …

Climate change and riparian management are major drivers of hydrological change, with
important implications for nutrient fluxes in lowland streams. However, the coupling of …
