Abstract:  Practicing hydrogeologists construct detailed numerical models to predict the responses of hydrologic systems to natural and applied stresses. These predictions form the basis for decisions that must balance optimal use of resources and ecosystem support. These decisions typically involve multiple interested parties with strongly differing priorities for water allocation. Despite the importance that stakeholders place on water resources, budgets for hydrogeologic studies are often limited. As a result, the hydrologic models used for decision support are severely data limited. This requires improved methods to identify the optimal set of observations to collect and use model-predictions to support robust decision-making under considerable uncertainty.

Ferré will build from the basic concepts of decision science to present concepts and recent developments in optimal design of hydrogeologic monitoring networks. He will also discuss how hydrogeologic models can be used for decision support under uncertainty. Finally, he will show that focusing hydrologic analysis on the specific, practical problems of interest can guide optimal measurement selection, advance hydrologic science and improve the integration of science into economic and policy decisions.

Approaches developed by leading researchers in the field will be presented, including work within Ferré’s research group on the Discrimination-Inference for Reduced Expected Cost Technique—a framework for integrating multimodel analysis and decision science to improve the efficiency and effectiveness of hydrogeologic investigations. Examples will demonstrate the application of decision-guided hydrologic investigations to the design of a pump and treat system, prediction of off-site exposure risk, estimation of future water availability and mediation of stakeholder conflicts over water use.

Bio: Ty Ferré, Ph.D., is a professor in the Department of Hydrology and Water Resources at the University of Arizona. He received his bachelor's degree in geophysical engineering from the Colorado School of Mines and his doctorate in Earth sciences from the University of Waterloo.

Ferré’s lecture, “Seeing Things Differently: Rethinking the Relationship Between Data, Models and Decision-Making” will build from the basic concepts of decision science to present concepts and recent developments in optimal design of hydrogeologic monitoring networks. He will also discuss how hydrogeologic models can be used for decision support under uncertainty. Finally, he will show that focusing hydrologic analysis on specific, practical problems of interest can guide optimal measurement selection, advance hydrologic science and improve the integration of science into economic and policy decisions.
