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 …

Storm events can mobilize nitrogen species from landscapes into streams, exacerbating
eutrophication and threatening aquatic ecosystems as well as human health. However, the …

Abstract Concentration‐discharge (C‐Q) relationships are frequently used to understand the
controls on material export from watersheds. These analyses often use a log‐log power‐law …

The export of anthropogenic nitrate to coastal waters, which depends on the interplay
between many factors such as land use and meteorological forcing, is a rising concern in …

Environmental impacts on freshwater ecosystems persist due to inputs of excess fertilizer to
agricultural landscapes. Conservation efforts, such as cover crops, are being encouraged to …

Shifts in water fluxes and chemical heterogeneity through catchments combine to dictate
stream solute export from the Critical Zone. The ways in which these factors emerge in …

Nutrient runoff from agricultural regions of the midwestern US corn belt has degraded water
quality in many inland and coastal water bodies such as the Great Lakes and Gulf of Mexico …

Constructed wetlands are standard conservation practices used to reduce nitrate loads in
agricultural watersheds. Many studies have examined the efficiency of denitrification in …

Across watershed science, two key variables emerge–streamflow and solute concentration–
which serve as the basis for efforts ranging from basic watershed biogeochemistry research …
