Abstract

Stream depletion is the reduction in the flow rate in a stream as a result of extraction of groundwater from a well from an aquifer that is hydraulically connected to the stream. The amount of stream depletion depends on hydraulic properties of the aquifer and stream, distance between the extraction well and the stream, and the pumping rate. In water scarce regions, groundwater extraction is only permitted if stream depletion can be shown to remain below a pre-specified threshold value. Thus, the quantification of stream depletion is of extreme importance. This seminar will present an overview of stream depletion and will highlight some recent advances in methods for calculating stream depletion.

Biography

Dr. Roseanna Neupauer is a Professor and President’s Teaching Scholar at the University of Colorado Boulder in the Department of Civil, Environmental and Architectural Engineering. She received a B.S. in Civil Engineering from Carnegie Mellon University, a B.A. in Spanish from University of Colorado, an M.S. in Civil Engineering from MIT, and an M.S. in Math and a Ph.D. in Hydrology from the New Mexico Institute of Mining and Technology. Her research focuses on groundwater flow and transport modeling, with applications to groundwater remediation, stream depletion quantification, subsurface hydrology in frozen and partially frozen ground, and protection of water supplies and groundwater dependent ecosystems from chemical and thermal contamination. She is a Fellow of the Geological Society of America and the Environmental and Water Resources Institute of the American Society of Civil Engineers.
