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

We face an urgent and complex challenge to produce large amounts of healthful animal and
plant foods for an estimated 10 billion people by 2050 while maintaining essential …

Eutrophication has threatened water resources worldwide, yet mechanistic understanding
on controls of nutrient export remains elusive. This work tests the shallow and deep …

In this chapter, the authors provide a comprehensive analysis and synthesis of the
interactions between important drivers and controls of hyporheic exchange and …

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

Elevated nitrogen (N) concentrations have detrimental effects on aquatic ecosystems
worldwide, calling for effective management practices. However, catchment-scale annual …

Human agriculture, wastewater, and use of fossil fuels have saturated ecosystems with
nitrogen and phosphorus, threatening biodiversity and human water security at a global …

Elevated nitrogen concentrations in streams and rivers in the Chesapeake Bay watershed
have adversely affected the ecosystem health of the bay. Much of this nitrogen is derived as …

Climate change is creating widespread ecosystem disturbance across the permafrost zone,
including a rapid increase in the extent and severity of tundra wildfire. The expansion of this …

Permafrost degradation is delivering bioavailable dissolved organic matter (DOM) and
inorganic nutrients to surface water networks. While these permafrost subsidies represent a …
