Phosphorus Pollution Reaching Dangerous Levels Worldwide

Press Release— Humans discharge four times the weight of the Empire State Building’s worth of phosphorus into freshwater bodies each year, a new study finds. Man-made phosphorus pollution is reaching dangerously high levels in freshwater basins around the world, according to new research. A new study published.... more

How Drought Plays Out

Emily Underwood, Freelance Writer

Research Spotlight— Humans are less likely to deplete groundwater when rainfall varies between years. Drought takes many forms. There’s meteorological drought, in which snow and rainfall are abnormally scarce. There’s hydrologic drought, in which rivers, lakes, and underground aquifers draw down or.... more

Urban Sewers Evolve Similarly to River Networks

Sarah Stanley, Freelance Writer

Research Spotlight— Like river systems, engineered drainage networks become increasingly fractal as they grow.  Beneath city streets, sewer systems direct the flow of wastewater toward treatment plants. Sewer pipe networks also drain storm water to prevent urban flooding. These urban networks perform.... more

Stronger storms hamper ability of streams and rivers to clean up pollution

Lori Wright

Blog— Researchers use high-technology sensors to understand water quality  Freshwater streams and rivers naturally clean up some forms of pollution originating from urban and agricultural areas, but increased storm intensity reduces this ability, which underscores the need to improve the management.... more

Blending Satellite Data to Monitor Agricultural Water Use

Terri Cook, Freelance Writer

From Research Spotlights— A new technique that merges data gathered by multiple satellites can be used to monitor agricultural water use and improve water quality assessments around the globe. As Earth’s growing population increasingly stresses global freshwater supplies, there is mounting.... more

How stream restoration projects affect hyporheic exchange

Editor’s Highlight—   This paper presents a new modeling approach to predict the effects of stream restoration on hyporheic exchange and nutrient retention. The modeling is based on the 1D transient storage approach for downstream transport coupled to a subsurface advection component. This approach.... more

What Causes Ecological Shifts?

Kate Wheeling, Freelance Writer

Editor’s Highlight—A network approach to understanding ecosystem processes  Temporal Information Partitioning Networks (TIPNets) is an approach presented by the authors of this paper to analyze information flows within a network of interacting variables. They apply the method to data from a weather.... more

What Causes Ecological Shifts?

Kate Wheeling, Freelance Writer

From Research Spotlights— A new information-processing framework helps researchers tease out the factors driving ecological shifts over short timescales.  Our environment is constantly changing—today faster than ever, thanks in large part to human activities. Understanding the forces and feedbacks.... more

Cosmic Ray Neutrons Reveal Mountain Snowpacks

Terri Cook, Freelance Writer

From Research Spotlights— The first application of aboveground neutron sensing to evaluate alpine snowpacks indicates that this method can reliably detect average snow depth and water content across intermediate distances. Because of their crucial importance to regional water supplies, mountain.... more

Modeling choices about stormwater investments

Editor’s Highlight—   This paper applies game theory to examine individual landowner investment in green infrastructure stormwater control investments. Because of location-dependent drainage effects, which landowners (and where) have a large effect on overall benefits and the cost effectiveness of alternative.... more
