Hydrologic data are at the core of our understanding of physical hydrologic processes, our
simulation models and forecasts of water resources and hazards, and our monitoring of …

Excessive riverine nutrient concentrations threaten aquatic ecosystem structure and
functioning and can pose substantial risks to human health. Robust monitoring strategies …

To investigate the prevalence and cause of concentration‐discharge (C‐Q) relationships for
carbon, nutrients, major ions, and particulates, we analyzed 40 years of water quality data …

New scientific understanding is catalyzed by novel technologies that enhance measurement
precision, resolution or type, and that provide new tools to test and develop theory. Over the …

Headwater, or first-order, catchments are the building blocks of drainage basins. They
contribute up to half of the mean water volume and nitrogen fluxes for fourth-order and …

The quality standards for surface waters increase steadily bearing new challenges for water
policy. Precise knowledge of the sources and transport pathway of various impacts in a …

Phosphorus losses from land to water will be impacted by climate change and land
management for food production, with detrimental impacts on aquatic ecosystems. Here we …

Stream nutrient concentrations exhibit marked temporal variation due to hydrology and other
factors such as the seasonality of biological processes. Many water quality monitoring …

The analysis of concentration-discharge (CQ) relationships provides useful information on
the processes controlling the mobilization and delivery of chemical elements into streams as …

Sensors and enabling technologies are becoming increasingly important tools for water
quality monitoring and associated water resource management decisions. In particular …
