Gulf of Mexico researchers examine effects of Hurricane Harvey floodwaters

What happens when a hurricane sends fresh rainwater — up to 124.9 trillion L (33 trillion gal) of it — into the saltwater ocean? In the case of normal-sized storms, the rainwater, which is less dense than saltwater, typically sits atop the ocean in a distinct “blob,” which generally mixes into the ocean within hours […]

Football stadium protects San Francisco Bay with state-of-the-art stormwater system

In 2014, when the San Francisco 49ers football team relocated to a new home stadium at the height of many years of drought in California, water sustainability was a high priority for designers. Installing forward-looking features such as a 2500-m2 (27,000-ft2) green roof, an innovative biofiltration system, and a display that offers information about the […]

Melting snow thought to increase likelihood of seasonal earthquakes in California

Each summer, winter accumulations of snow in California’s various mountain ranges begin to melt. As they do, millions of liters of stormwater flow groundward, refilling aquifers and reservoirs while quenching farmland. When this much water falls from the mountains in an abbreviated period, it can spell disaster for those living below, as was almost the […]

UC Davis, GE, and Winesecrets turn stormwater into wine

In 2015, California vineyards produced more than 2.4 billion L (638 million gal) of wine, according to the Wine Institute (San Francisco). And now, a California partnership is leading the charge to convert stormwater into wine. The Water Footprint Network (The Hague, Netherlands) estimates that each gallon of wine requires a staggering 3300 L (872 […]

Stormwater infiltration pilot project in California aims to boost aquifer recharge

A pilot project is testing the feasibility of using specially-designed ponds for catching stormwater and facilitating groundwater recharge in the Pajaro Valley region of California’s Central Coast, where aquifer levels are dwindling from overuse brought on by severe drought conditions. Andrew Fisher, a University of California, Santa Cruz hydrogeologist who is leading the project, built […]

Farmers Flood Fields To Replenish Groundwater

This winter, some California farmers will be flooding their fields to replenish groundwater. El Niño is expected to deliver a warmer, wetter winter season to California, and farmers are hoping to capitalize on the extra water by directing floodwater and stormwater to their fields. The water will percolate through the soil and into the aquifer […]
