Water Luncheon Webinar
Hosted by Ohio Water Resources Center

Floods, Droughts and Contamination: A water manager’s perspective on climate change and human health

Dr. Patrick Ray, Assistant Professor, Engineering Research Center at the University of Cincinnati, Department of Chemical and Environmental Engineering



Approximately 50% of the world’s people live within 3 km of a river, and are vulnerable to streamflow extremes (flood/drought) and inadequate water quality. These two problems are linked (and likely to worsen with climate change); however, the linkages are only poorly understood. Floods mobilize contaminants stored on the floodplain and overwhelm containment and treatment works. Droughts lower water levels, elevating pollutant concentrations, and stagnating flows (decreasing river re-oxygenation). In combination with warming waters, droughts increase the likelihood and severity of harmful algal blooms (HABs). This talk will provide background on the relationship between climate warming and hydrologic variability, and offer anecdotes of linkages with water quality problems, such as Hurricane Harvey in Houston, and repeated, varied, contamination of the Ohio River. The talk will conclude with discussion of what can be done to better characterize our risks, so that strategic investments can be made to reduce them.

Wednesday, December 8, 2021, 12:00 PM until 1:00 PM
Hosted by the Ohio Water Resources Center and the Water Management Association of Ohio.

Patrick Ray is an Assistant Professor of Environmental Engineering at the University of Cincinnati, and a member of the Hydrosystems Research Group at the University of Massachusetts, Amherst. His research focuses on increasing the resilience of water systems to climate variability and change through the use of advanced climate science and coupled hydrologic-human system simulation. He aims at pragmatism, and decision relevance in a highly uncertain world. His academic work has been supported by approximately two million dollars of grants and awards, including, among others, a National Science Foundation Graduate Research Fellowship, a Fulbright Fellowship, and grants from the World Bank, UNESCO, the Millennium Challenge Corporation, the U.S. Army Corps of Engineers, the University Center for Atmospheric Research, and the California Department of Water Resources. Because of his role in the development of the World Bank’s Decision Tree for Confronting Climate Uncertainty, he shared in the World Bank’s 2015 Knowbel Prize for “Understanding the Impact of Climate Change and Other Risks on Hydropower”, and in 2018 he was named the A. Ivan Johnson Outstanding Young Professional of the American Water Resources Association.
