The University of Arizona (UA) Water Resources Research Center (WRRC) will be hiring two post-doctoral research associates into 24-month positions beginning in early 2022. These opportunities both provide a foundation for building a research portfolio and contributing to greater awareness and understanding of water resources in Arizona and the West. Both positions require that the candidate hold a PhD in a field with relevance to the position description at the time of hiring.
Summary of Net Zero Urban Water from Concept to Applications: Integrating Natural, Built, and Social Systems for Responsive and Adaptive Solutions
UArizona Assistant Professor Courtney Crosson.
Some major points of the article are:
- Multiscale and multidimensional decision support is needed to adapt the built environment toward a NZUW future, in view of natural and social system dynamics and constraints.
- To reach a NZUW target, an urban water system will need to implement adaptive and responsive solutions across building, district, and city and regional scales.
- Net zero water technologies have been demonstrated at the building scale and incentives have been adopted by several districts and cities. Implementation barriers exist at all scales and require a shift in policies, governance and management structures, and technological improvements for comprehensive adaption to the urban water system.
- Six areas of research gaps across the NZUW approach are identified in the article: (1) alternative water sources and retrofit, (2) distributed soft infrastructure, (3) surface and groundwater interactions, (4) treatment and management technologies, (5) public preference, and (6) policy and governance.
- NZUW has similarities with Integrated Urban Water Management, Water Sensitive Urban Design, and One Water concepts. The key differentiation between NZUW and these previous integrated urban water concepts is its overarching goals. While Integrated Urban Water Management emphasizes cost-effective infrastructure planning, NZUW expands the goal to achieving self-sufficiency. NZUW goes beyond One Water by providing a quantitative framework to assess the tradeoffs between multiple adaptation options.
- Overall, the resulting quantitative framework is a tool for making comprehensive decisions across multiple systems with various stakeholders to move our water systems towards NZUW. The system-wide framework represents the potential responses to acute shocks and chronic stressors, as well as the associated uncertainties, over a forecast time horizon. Using this information, the tradeoffs across the built, natural, and social systems can be evaluated for decision support. Example outcomes may include physical infrastructure retrofit, policy or governance changes, or inter-agency agreements for overall water management oversight.

On Wednesday, November 10, the WRRC hosted a Brown Bag webinar featuring presentations by student researchers who received funding in 2020 through the WRRC from the Water Resources Research Act, Section 104(b) grant program.
Did you know that the WRRC was part of the bipartisan infrastructure bill? The Infrastructure Investment and Jobs Act, signed into law this week, contains historic investment in water resources and, of particular importance to the WRRC
The American Water Resources Association (AWRA) Annual Water Resources Conference was held virtually this week, November 8-10, 2021. On the first day of the conference, WRRC Director Sharon B. Megdal and Graduate Student Assistant Simone A. Williams presented at two separate sessions on different WRRC efforts.
