  • Dusty News: Technology Expected to Help Drivers in Arizona Dust Storms

    Wednesday, June 26, 2019
    The Arizona Department of Transportation is set to use a $54 million federal grant to widen sections of I-10 and implement a project that would reduce dust-related crashes. The project includes long-range radar set near Picacho Peak that can detect approaching dust storms from 50 miles away. The Arizona Department of Transportation recorded 85 dust-related crashes along the busy freeway from Phoenix to Tucson from 2010 to 2015. According to a 2016 report by the National Weather Service and the UA, dust is the third-leading cause of weather-related deaths behind extreme temperatures and flash f... Read More

    Groundwater pumping in the last century has contributed as much as 50 percent to stream flow declines in some U.S. rivers, according to new research led by HAS Assistant Professor Laura Condon. This is the first study to look at the impact of past groundwater pumping across the entire U.S. Other researchers have examined how pumping has affected surface waters, but at smaller scales. This comprehensive study is extremely important because groundwater is often the slowest component of the terrestrial hydrologic system to recover from losses, Condon said. Using a computer model, Condon and her c... Read More
