Billions spent worldwide to improve “natural” green infrastructure

The term green infrastructure generally refers to manmade structures that mimic the absorptive water control properties of nature. But more and more engineers, academics, and regulators are recognizing that the term also includes the very forests, meadows, and wetlands that inspire bioswales, porous hardscapes, and rain gardens. Last September, Governor Jerry Brown of California introduced […]

Tree hydration system made from recycled diaper material minimizes stormwater runoff

Using watering bags to nurture young trees can help ensure a moist soil environment as the plants develop root structure. But standard watering bags require constant refills, and do little to deter stormwater runoff pollution. However, a new product made from the same material used in disposable diapers can catch and retain rainwater before releasing […]

NCAR study portends extremely rainy 21st century

If trends toward warmer climates continue at the same pace that they have during the last few decades, the U.S. could see extreme rainfall events up to four times more frequently by the end of the 21st century, a new study by the National Center for Atmospheric Research (NCAR; Boulder, Colo.) finds. These storms could […]
