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.

My name is Juliana, and I am one of four AmeriCorps Water Educators in Tucson working with Arizona Project WET (APW). So much happened in our first few weeks on the job. We all jumped right into the action. As water educators, we are tasked with teaching students from 4th grade all the way through high school through APW’s different programs. During the first month, in addition to learning about water and how to lead the lessons through training and seminars, we also had firsthand teaching experiences.
On Friday, October 28, the US Bureau of Reclamation (Reclamation) announced the initiation of an expedited process for developing a “Supplemental Environmental Impact Statement (SEIS)” on proposed revisions to the December 2007 Record of Decision relating to the Colorado River Interim Guidelines. The SEIS will lay out options to address the troubling operating conditions facing the river system now and in the future. Public comments submitted by December 20 will be reflected in the draft SEIS to be released next spring, with the final expected in late summer.
The WRRC has three great events lined up for this month. Next week, on Thursday, November 10, we will be hosting a Brown Bag webinar featuring two University of Arizona (UArizona) graduate students who will each present on their 104(b) research projects. The presentation from Chandler Noyes will address the paleoclimate and past recharge rates in the Tucson Basin across the Holocene.
