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 …

Abstract Concentration–discharge (C‐Q) relationships reflect material sources, storage,
reaction, proximity, and transport in catchments. Differences in hydrologic pathways and …

Estimating constituent loads from discrete water quality samples coupled with stream
discharge measurements is critical for management of freshwater resources. Nutrient loads …

Understanding where nitrate is mobilized from and under what conditions is required to
reduce nitrate loss and protect water quality. Low frequency sampling may inadequately …

Widespread deployment of sensors that measure river nitrate (NO3−) concentrations has led
to many recent publications in water resources journals including review papers focused on …

Karst terrain seasonal monsoonal rainfall is often associated with high concentrations of
nitrate-N in streams draining agricultural land. Such high concentrations can pose problems …

Urbanization contributes to the formation of novel elemental combinations and signatures in
terrestrial and aquatic watersheds, also known as 'chemical cocktails.'The composition of …

The analysis of concentration‐discharge (C‐Q) relationships from low‐frequency
observations is commonly used to assess solute sources, mobilization, and reactive …

There is growing global concern that greenhouse gas (GHG) emissions from water bodies
are increasing because of interactions between nutrient levels and climate warming. This …
