WRRC Director Sharon B. Megdal and WRRC Assistant Director Susanna Eden recently co-authored an article on a modeling framework analysis that incorporates climate projections for water resources management in the Upper Santa Cruz River in Arizona.  The article, “Climate change and water resources management in the Upper Santa Cruz River, Arizona,” was published in the Journal of Hydrology and is now available online, free of charge.   Highlights of the article:

On Monday, December 8, WRRC Director Sharon B. Megdal and Associate Director Jean McLain met with eight women scientists from Pakistan to discuss issues related to agricultural water use in Arizona and current research projects focused on water use by irrigated food crops. The scientists are visiting locations in the U.S. from November 29 to December 19 under the Women in Agriculture: Developing the Next Generation of Leaders project. They were invited to the U.S. under the auspices of the Department of State’s International Visitor Leadership Program.

Section 104 of the Water Resources Research Act (WRRA) of 1984 authorizes annual funding to support an institute for water resources research in each state at its land grant college or other designated university. Currently there are a total of 54 U.S. water institutes in the states and in Pacific islands. The Water Resources Research Act Program, administered by the U.S.

Streams and aquifers are hydraulically connected in many hydrologic systems across Arizona.  Such a connection occurs when the groundwater level in an aquifer intersects a stream, spring, or even the roots of riparian plants.  In these hydraulically-connected systems, the surface water and groundwater interact as a stress imposed on one part has an effect on the other.  Often this interaction is observed as a reduction in stream base flow caused by groundwater withdrawals from a connected aquifer – a process often called “streamflow depletion” or “capt

Arguably, fresh water is becoming our most valuable commodity. Where once we could expect to turn on the tap and receive a never-ending supply of fresh, clean, safe water —climate and contamination are threatening to upend this reliability. For this reason and due to his innate curiosity, Professor Brian Berkowitz of Weizmann Institute of Science in Israel has a research focus that centers around experimental analysis and computer modeling of fluid and chemical transport through geological formations, with an emphasis on groundwater systems.

Host Gilad Halpern is joined by Prof. Sharon Megdal, director of the Water Resources Research Center at the University of Arizona, US. She visited Israel for the ‘Drylands, Deserts and Desertification Conference’ at Ben-Gurion University. Megdal discusses how limited water resources should be managed in arid areas like Israel and Arizona, and what she has learned from – as well as taught – her Israeli colleagues.

In celebration of its 70th anniversary (1945-2015), the Colorado River Water Users Association (CRWUA) has put together a detailed timeline of the history of the Colorado River from 1869 to the present. The timeline displays key water events including negotiations over the apportionment of the River, important acts, international treaties, and some of CRWUA’s work.

On Nov. 14, Director of the UA Water Resources Research Center (WRRC), Sharon B. Megdal was named Morrison Institute Distinguished Fellow at the Institute’s annual State of Our State Conference. The title of Distinguished Fellow was created in 2012 to not only recognize Arizona’s best and brightest in public policy, but also tap into their knowledge and expertise for their insights on certain policy-relevant issues.

A new report by the United States Geological Survey (USGS) shows water use across the country reached its lowest recorded level in nearly 45 years. Water withdrawals in the United States in 2010 were estimated to be about 355 billion gallons per day (Bgal/d), which was 13 percent less than in 2005.

Sharon B. Megdal, Director of the Water Resources Research Center (WRRC), recently co-authored an article on the Colorado River and the Jordan River with Assaf Chen (Ben-Gurion University of the Negev, Israel), Adam Abramson (Ben-Gurion University) and Nir Becker (Tel-Hai College, Israel), which was published Nov. 12 in the Journal of Arid Environments.

DAMNED IF WE DON’T! Ideas for accelerating change around water is a series of essays written by thought leaders who are addressing, head-on, the issues surrounding water. With an intention to share ideas, broaden perspectives and encourage people to continue with an ongoing dialogue, this book represents a shared vision to help accelerate much needed change around water.

You know that trickle of water you see exiting the pipe connected to your home air conditioning system?  For large commercial buildings condensate water from heating, ventilation and air-conditioning (HVAC) systems can add up to more than a million gallons per year.  Routing this water to the sewage drain not only wastes water that can be used for non-potable applications on-site, it also unnecessarily burdens the city’s water treatment system.  As you can imagine, the drought across the southwestern United States has prompted a serious look at alternative water sources
