Expert Interviews with DCDC Researchers
May 31, 2016Here & Now’s Meghna Chakrabarti talks with Dave White at Arizona State University about why the lake is so low, and what happens if the level falls low enough to trigger mandatory water restrictions.
Water Level At Lake Mead, The Country’s Largest Reservoir, Is At Historic LowLake Mead along with Lake Powell, the two major storage reservoirs on the Colorado River system, are absolutely essential to the social, economic and environmental vitality for the entire western United States. Together, the reservoirs and the Colorado river system provide at least part of the drinking water supply to nearly 40 million people in the western United States, produce millions of megawatt hours of energy production, provide habitat for threatened and endangered species and produce a tremendous agricultural crop particularly during the winter months.
May 30, 2016Dave White is interviewed by AZCentral.com’s Brandon Loomis on Nestle planning a $35 million plant to bottle water in Phoenix.

May 23, 2016Steve Goldstein at KJZZ’s Arizona Science and Innovation Desk, interviews Dave White regarding the Southwest drought and its impact on Lake Mead and the Lower Colorado Basin.
How Arizona, Western States Plan To Deal With Possible Water ShortagesThe Southwest drought continues, and its impact is being felt in Lake Mead. The Colorado River reservoir has shrunk to its lowest levels since the completion of Hoover Dam in 1936. The lake is only 37 percent full. They talked about what that could mean for Arizona and what some Western states are planning to do about it with Dave White, director of the Decision Center for a Desert City at Arizona State University.
March 3, 2016DCDC Water/Climate Briefing panelists share the good, the bad and the hopeful of water in the West.
Experts share the good, the bad and the hopeful at panel hosted by ASU’s Decision Center for a Desert CityThe Colorado River provides water for nearly 40 million people in seven western states, irrigating millions of acres of farmland, and generating thousands of megawatts of electricity. And though an official declaration of water shortage on the Colorado River has never been declared, and that careful planning has ensured Arizona and Colorado are well-supplied with water, residents need to know it’s a precious resource. That was the message Thursday as the water chieftains of Arizona and Colorado spoke before a crowd of about 100 at the Water/Climate Briefing Annual Keynote Event held by Arizona State University’s Decision Center for a Desert City.
February 18, 2016ASU researchers report on a range of topics at 2016 AAAS conference from effective team science to drones on the range, Arizona State University faculty and students played a big role in the annual meeting of the American Association for the Advancement of Science (AAAS).

February 17, 2016DCDC scientists Ted Bohn and Enrique Vivoni discuss their research
Satellite imagery and models to help secure water resources in the arid SouthwestArizona State University scientists Ted Bohn and Enrique Vivoni, of the School of Earth and Space Exploration, discuss a new technique in the journal Water Resources Research, which uses a combination of satellite imagery, field observations and models to estimate evapotranspiration – evaporation from soils and from plant transpiration. Evapotranspiration is an important component of the hydrological cycle and a major contributor to downwind rainfall.
February 14, 2016Enrique Vivoni interviewed regarding his use of UAVs in his research
Drones helping scientists to capture high-resolution images“Unmanned Aerial Vehicles (UAVs) are poised to revolutionize remote sensing in the earth and environmental sciences. They let individual scientists obtain low-cost repeat imagery at high resolution and tailored to a research team’s specific interest area,” said Enrique Vivoni, hydrologist and professor at Arizona State University. Vivoni did his research in the Sonoran and Chihuahuan deserts which cover large expanses of northern Mexico and the US Southwest. Using drones in these areas allowed the scientists for improved studies on land-atmosphere exchanges and vegetation-runoff interactions.
February 8, 2016Dave White facilitates a meeting of Western city mayor’s at summit.
Fostering collaboration to address water sustainabilityCities in the United States’ Western region face a higher demand for water as populations grow and drought diminishes supply. That’s why the mayors of several Western cities recently agreed to work together on water sustainability and climate-change adaptation. “As they like to say, mayors have to get stuff done. They are problem solvers with very immediate constituencies,” said Dave White, director of Arizona State University’s Decision Center for a Desert City, a research unit of the Julie Ann Wrigley Global Institute of Sustainability.
February 5, 2016Enrique Vivoni discusses UAVs revolutionizing remote sensing in the earth and environmental sciences
Drones give scientists a new self-service approachThanks to the increased affordability and dramatic technological advances of drones, or Unmanned Aerial Vehicles (UAVs), however, earth and environmental scientists can now conduct their own long-term high-resolution experiments at a fraction of the cost of using aircraft or satellites. “UAVs are poised to revolutionize remote sensing in the earth and environmental sciences,” says Enrique Vivoni, hydrologist and professor at Arizona State University’s School of Earth and Space Exploration and Ira A. Fulton Schools of Engineering. “They let individual scientists obtain low-cost repeat imagery at high resolution and tailored to a research team’s specific interest area.”

Parched Cities Share Water in the West
A recent agreement by this city and Tucson, Ariz., highlights a growing trend in the drought-plagued Southwest: water agencies sharing resources to stretch limited supplies rather than going it alone. Phoenix, which gets more water than it can store from the Colorado River, has agreed to send some of its surplus to Tucson, which needs it to lower pumping costs. In return, Tucson will give up part of its share of Colorado River water to Phoenix when needed. The deal finalized in early October comes despite long-standing rivalries between Arizona’s two largest cities.
