Massive Gulf of Mexico dead zone threatens economy and water quality

The U.S. National Oceanic and Atmospheric Administration (NOAA) predicts the Gulf of Mexico’s annual summer dead zone – a low-oxygen area which can cause mass death of marine life – will grow over 40% this year compared to last summer, approaching the size of Massachusetts. The effects of this year’s dead zone on the local […]

San Antonio invests $2.6 million in new Edwards Aquifer protection efforts

In June, the City of San Antonio awarded $2.6 million to researchers at the University of Texas at San Antonio (UTSA) to support three stormwater management projects over the next 3 years, according to a UTSA release. Each project protects the Edwards Aquifer by lowering risks of runoff contamination. Lying beneath south-central Texas, the massive, […]

Permeable pavement guide helps practitioners avoid pitfalls

To take full advantage of permeable pavement, a green alternative to traditional concrete or asphalt pavers that collect and filter stormwater runoff, infrastructure planners must take many site-specific factors into account. A new guide to permeable pavements written by researchers from the University of Florida Institute of Food and Agricultural Sciences (UF–IFAS; Gainesville) helps developers, […]

USGS estimates impervious parking lot coverage for all 3,109 U.S. counties

According to automotive industry analysts with Hedges & Co. (Hudson, Ohio), there were more than 275 million registered motor vehicles in the U.S. in 2018. Accommodating that number of vehicles requires an enormous network of parking lots, the vast majority of which are made of impervious pavement that rainwater cannot infiltrate. Until now, researchers have […]

Groundwater injection turns a challenge into an opportunity, say University of Texas researchers

As the saying goes, everything is bigger in Texas — including the water management challenges. Depending on the weather, many Texans routinely deal with either too much or too little water. Over two weeks in 2017, for example, Hurricane Harvey delivered approximately 80 million acre-feet of water to southeastern parts of the state — enough […]

New flood model: Slight increases in rainfall can create major traffic disruptions

Many of the modeling tools that public works agencies, disaster response organizations, and watershed managers use to predict the effects of flooding from major storms do not consider a detail that makes a major difference, according to new research: land elevation. A study published in May in the journal Nature Communications describes a new flood-modeling […]
