Fifty years of hyporheic zone research have shown the important role played by the
hyporheic zone as an interface between groundwater and surface waters. However, it is only …

Previously regarded as the passive drains of watersheds, over the past 50 years, rivers have
progressively been recognized as being actively connected with off‐channel environments …

Hydrological precipitation and snowmelt events trigger large “pulse” releases of terrestrial
dissolved organic matter (DOM) into drainage networks due to an increase in DOM …

Hydrologic connections can link hillslopes to channel networks, streams to lakes, subsurface
to surface, land to atmosphere, terrestrial to aquatic, and upstream to downstream. These …

Increased loading of nitrogen (N) and phosphorus (P) from agricultural and urban
intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs …

Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing, and
terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more …

Over the past 3 decades, nutrient spiraling has become a unifying paradigm for stream
biogeochemical research. This paper presents (1) a quantitative synthesis of the nutrient …

Human activities have greatly increased the transport of biologically available nitrogen (N)
through watersheds to potentially sensitive coastal ecosystems. Lentic water bodies (lakes …

The Integrated Model to Assess the Global Environment–Global Nutrient Model (IMAGE–
GNM) is a global distributed, spatially explicit model using hydrology as the basis for …

Corn cultivation in the United States is expected to increase to meet demand for ethanol.
Nitrogen leaching from fertilized corn fields to the Mississippi–Atchafalaya River system is a …
