Study Shows Importance of Particle Size Distribution in Stormwater Control Sizing

Particle size distribution (PSD) significantly affects stormwater controls that rely on settling to remove sediment. A new study by researchers with the U.S. Geological Survey Wisconsin Water Science Center demonstrates the importance of knowing PSD for properly sizing these stormwater controls. Published Jan. 6 in the open-access journal Water, “The effect of particle size distribution […]

Australian Community Launches Large-Scale Floating Wetlands Project

Parklakes II, a master-planned residential community within Bli Bli on the Sunshine Coast of Queensland, Australia, will soon be home to a unique floating wetland installation. The first of the 230 pontoons that support the vegetation were launched Nov. 25. Eventually the pontoons will cover 2100 m2 of a 2.5 ha lake and will be […]

Benefits of Green Development Clear in Side-By-Side Comparison with Conventional Development

In Norman, Okla., the Trailwoods community is demonstrating the benefits of green infrastructure when compared side-by-side with traditional stormwater management techniques. The neighborhood, developed by Ideal Homes, includes 17 lots constructed with curb and gutter and downspout-to-driveway conveyance as well as two stormwater basins. Another 17 lots are designed with rain gardens, rain barrels, and […]

Researchers Test Trees Effectiveness in Removing Nutrients from Urban Stormwater

Researchers at the University of Melbourne tested trees’ ability to remove nutrients from urban stormwater in a study recently published in the Journal of Environmental Quality. The researchers examined the ability of four different tree species commonly used to line Australian streets in a 13-month experiment. Species included red box, brush box, white bottlebrush, and […]

Researchers Assess Green Infrastructure Effects at the Catchment Scale

In a new study, Kent State University and Cleveland Metroparks researchers have collected some of the first data testing the effectiveness of green infrastructure projects at the watershed scale. “[Green infrastructure] strategies are used throughout the country and in other countries, but the novel thing is that we were able to demonstrate that they work […]

New Water-Tracing Technology Reveals Groundwater Movement

University of New South Wales (UNSW) researchers have used a new water-tracing technology in the Sydney Basin of Australia for the first time to determine how groundwater moves in the different layers of rock below the surface. The study provides a baseline against which any future effects on groundwater from mining operations, groundwater abstraction, or climate […]

Beavers Help Remove Nitrogen in Streams, Research Says

According to University of Rhode Island (URI) professor Arthur Gold, beavers can help prevent harmful levels of nitrogen from reaching vulnerable estuaries. URI researchers found that the water retention time and the build-up of organic matter in beaver ponds lead to ideal conditions for nitrogen removal. These conditions can result in removal of 5% to […]

Students Design Sustainable Storm Drain Filter

A team of students from the University of California–Riverside (UC Riverside) Bourns College of Engineering recently received a $15,000 grant from the U.S. Environmental Protection Agency for a low-cost, environmentally friendly, reusable storm drain filter. The team received the funding as a phase one winner of EPA’s People, Prosperity and the Planet competition. Storm-drain inserts can be […]
