2016 Darcy Lecture Series in Groundwater Science

Seeing Things Differently: Rethinking the Relationship Between Data, Models, and Decision-Making

Ty Ferré, Ph.D.

Tuesday, April 26, 8:35-9:30 a.m.

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 to use model-predictions to support robust decision-making under considerable uncertainty.

Dr. 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.

Special presentation — Darcy Revisited

Tuesday, April 26, 9:30-110:30 a.m.

Join three former NGWREF Darcy Lecturers as they address the advances made within their topic areas since their official Darcy Lecturer year.



Mary C. Hill, Ph.D., a professor in the Department of Geology at the University of Kansas, will provide updates on her 2001 Darcy Lecture, “Guidelines for Effective Model Calibration (Any Model!),” which focused on how nonlinear regression and associated statistics can be used to dramatically improve how data are used to calibrate and text models.

Kip Solomon, Ph.D., a professor in the Department of Geology & Geophysics in the University of Utah’s College of Mines and Earth Sciences, will provide updates on his 2005 Darcy presentation, “Inert Gas Tracers in Ground Water” that illustrated the basic concepts of using inert gas tracers along with case studies describing their applications to real-world groundwater flow problems.

Michael Celia. Ph.D., director of the Program in Environmental Engineering and Water Resources in the Civil and Environmental Engineering department at Princeton University, as well as a professor, will provide updates on his 2008 Darcy Lecture, “Geological Storage as a Carbon Mitigation Option,” which talked about carbon capture and storage, or CSS, as one approach to reducing atmospheric carbon dioxide.
