Timothy Scheibe, the 2010 Darcy Lecturer, presented the talk, “Quantifying Flow and Reactive Transport in the Heterogeneous Subsurface Environment: From Pores to Porous Media and Facies to Aquifers” as the 2010 Darcy Lecturer on Thursday, January 7, 2009 at 499 Dirac Science Library. Dr. Scheibe is the first person from the national laboratories of the Department of Energy to be named Darcy Lecturer. The Henry Darcy Distinguished Lecture Series in Ground Water Science was established in 1986 to foster interest and excellence in groundwater science and technology. The award honors and is named for Henry Darcy of France for his 1856 scientific discoveries which established the physical basis on which groundwater hydrogeology has been studied since that time. Since its inception, series lecturers have reached more than 70,000 national and international groundwater students, faculty members, and professionals
Dr. Scheibe joined Pacific Northwest National Laboratory in September 1992 and is currently a staff scientist in the Hydrology Technical Group. He received his bachelor’s degree in geological engineering from Washington State University, a master's in civil engineering from the University of Washington, and a Ph.D. in civil engineering from Stanford University. At PNNL, he has been responsible for proposal development, project management, and technical contributions in a number of different areas of environmental research and technology development broadly related to the hydrologic sciences. His primary research focus is on characterization and numerical simulation of natural subsurface heterogeneity, and its impacts on biogeochemically reactive transport in groundwater systems.
Dr. Schiebe plans to give 70 lectures all over the world, a new record for the Darcy lecturer. In his lecture on Quantifying Flow and Reactive Transport, he presented recently developed numerical methods and cutting-edge software for simulating groundwater flow and reactive transport at various scales, from pore scale, where the complex geometry of solid grains and pore spaces is explicitly quantified, to aquifer scale, where upscaling is entailed.
Professor Ming Ye, DSC resident hydrologist, invited Dr. Schiebe to the university. The lecture was attended by faculty, staff and students from many departments, and was followed by a reception in the commons.
