niversity of Arizona was well represented at the Universities Council on Water Resources (UCOWR) and The National Institutes for Water Resources (NIWR) annual conference held on June 11-13.
Climate Change and Water Resources Management in the Upper Santa Cruz River, Arizona
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:
- Climate projection in Southern Arizona increase uncertainty in rainfall patterns.
- Future climate is expected to decrease groundwater recharge from streamflow.
- Sound management can alleviate the impact of projected future climate.
- Water resources management strategies can affect long-term reliability of water supplies.

Managed aquifer recharge (MAR) is the intentional recharge (and storage) of water into an aquifer for future recovery or for environmental benefits. Mary Belle Cruz Ayala, a Ph.D. Student in Arid Lands Resource Sciences and a Graduate Research Assistant at the WRRC, recently presented her research on this topic at the 10th International Symposium on Managed Aquifer Recharge (ISMAR10) in Madrid, Spain. Her presentation, "Use of Managed Aquifer Recharge to Improve Water Management in Arid and Semi-Arid Regions of Mexico," presented results from the first paper from her Ph.D.
Each year, we are excited to see so many excellent students graduating and starting off on their academic or professional journeys. Last Friday, Elia Tapia, who has been working at the Water Resources Research Center (WRRC) as a Graduate Research Assistant, and most recently as a Senior Research Specialist, received a Ph.D. in Arid Lands Resource Sciences with a minor in Hydrology. Elia has been with us since 2014, working on both the Transboundary Aquifer Assessment Program (TAAP) and the Water RAPIDS Program.
Mandla Kunnie has created a digital database of the locations of all rainwater harvesting infrastructure in the Tucson area. Such a database can help water managers plan for population growth and the associated increased demand on water resources.
World Water Day is a good day for reflection. Just a few days ago, on March 19, 2019, representatives of the seven states of the Colorado River Basin gathered in Phoenix, Arizona to sign a letter asking Congress to approve implementation of the drought contingency plans detailed in the documents attached to the letter.
