David Yates is a Scientist in the Research Applications Laboratory at the National Center for Atmospheric Research, Boulder Colorado and an SEI Associate located in Boulder, Colorado. His research has focused both on local scale hydrologic problems (flash floods, land use-land cover, climate change), as well as climate change impacts and adaptation on water and agricultural systems. Dr. Yates has been a part of the development team of SEI's Water Evaluation and Planning model and has focused on applying WEAP to help water utilities with long-range planning that includes climate change impacts and adaptation strategies. With his NCAR colleague, Kathleen Miller and support from the Water Research Foundation, Dr. Yates developed an educational primer for use by the drinking water utility industry that outlines the current state of scientific knowledge regarding the potential impacts of global climate change on water utilities, including impacts on water supply, demand and relevant water quality characteristics. A follow-on study with The Foundation has focused on robust adaptation strategies, with several utilities, including the Inland Empire, El Dorado Irrigation District, Portland Water, Colorado Springs Utilities, Massachusetts Water Resource Authority, Durham Water, and Palm Beach County Water.

David Yates received his PhD in Civil and Environmental Engineering from the University of Colorado, Boulder in 1996.

Water-energy nexus challenges & opportunities in the Arabian Peninsula under climate change

Poster presented at the American Geophysical Union Fall Meeting, San Francisco, 12-16 December 2016

Author(s): Flores, F. ; Yates, D. ; Galaitsi, S. ; Binnington, T. ; Dougherty, B. ; Vinnaccia, M.; Glavan, J.C.
Year: 2016

Research Area(s): Water Resources

Description:

This conference poster presents the results of a study of the water-energy nexus in countries in the Arabian Peninsula, using a coupled WEAP-LEAP model. Demand for water in the Gulf Cooperation Council countries relies mainly on fossil groundwater resources and desalination. Satisfying water demand requires a great deal of energy, as it requires treating and moving water along the supply chain from sources, through treatment processes, and ultimately to the consumer. As part of the Abu Dhabi Global Environmental Data Initiative (AGEDI) Local, National, and Regional Climate Change Programme, a study of the water-energy nexus of the countries in the Arabian Peninsula was implemented. For water, WEAP models both water demand – and its main drivers – and water supply, simulating policies, priorities and preferences. For energy, LEAP models both energy supply and demand, and is able to capture the impacts of low-carbon development strategies. A coupled WEAP-LEAP model was then used to evaluate the future performance of the energy-water system under climate change and policy scenarios. The models examined five policy scenarios of different futures of resource management to the year 2060.

Technical Report: Al Ain Water Resources & Climate Change

Technical Report

Author(s): Flores, F. ; Yates, D. ; Galaitsi, S.
Year: 2016

Research Area(s): Water Resources

Description:

Water use in the Al Ain region of the UAE has exploded in the modern era, with the development of thousands of groundwater wells. The overall goal of the sub-project was to better understand Al Ain's water and agricultural management challenges in the face of climate change and socioeconomic development.

The SEI's Water Evaluation And Planning (WEAP) system was used for this analysis. The results of analysis confirm that climate change will impact the region's water resources, although in a salutary way.

Water Resources: Regional Water-Energy Nexus and Climate Change

Technical Report

Author(s): Flores, F. ; Galaitsi, S. ; Yates, D.
Year: 2016

Research Area(s): Water Resources

Description:

This paper explores the vulnerability of the Arabian Peninsula’s water resources to climate change, with the overall goal of better understanding the water-energy nexus challenge in the region. Using WEAP and LEAP, it confirmed that green growth objectives will increase the resilience of the water-energy nexus in the region under climate change. Moreover, this can be achieved cost-effectively.

Water Resources: National Water-Energy Nexus and Climate Change

Technical Report

Author(s): Flores, F. ; Galaitsi, S. ; Yates, D.
Year: 2016

Research Area(s): Water Resources

Description:

This paper looks at the water-energy nexus challenge in the United Arab Emirates in the face of climate change and socioeconomic development. Both water resource management and energy management are recognized as serious challenges to long-term sustainable development. Using WEAP and LEAP, the study confirmed that green growth objectives will increase the resilience of the water-energy nexus in the UAE under climate change.

Addressing Climate Change in Local Water Agency Plans: Demonstrating a Simplified Robust Decision Making Approach in the California Sierra Foothills

RAND Corporation Research Report RR-491-CEC

Author(s): Groves, D.G. ; Yates, D. ; Mehta, V. ; Bloom, E.; Johnson, D.R.
Year: 2013

Research Area(s): Water Resources

Description: Water agencies are increasingly seeking to address climate change in their long-term planning. Doing so, however, requires moving beyond traditional planning approaches to ones that can incorporate information about future hydrologic conditions, demographic changes, and other management conditions that are deeply uncertain or not statistically well characterized. This report describes an approach for planning under deep uncertainty, called Robust Decision Making (RDM), and demonstrates its application in a research study with the El Dorado Irrigation District (EID), a water agency located in the California Sierra Nevada Mountains. Using RDM, the authors, in collaboration with EID, tested the robustness of their current long-term plan across more than 50 futures reflecting different assumptions about future climate, urban growth, and the availability of important new supplies.
