Streaming Video Seminar — A Bi-State Aquifer Study: Modeling the Spokane Valley-Rathdrum Prairie aquifer in Washington and Idaho

Dr. Paul A. Hsieh, USGS

U.S. Geological Survey (USGS) scientist Dr. Paul A. Hsieh presented the seminar "A Bi-State Aquifer Study: Modeling the Spokane Valley-Rathdrum Prairie aquifer in Washington and Idaho," Menlo Park, California, September 13, 2007. Dr. Hsieh and other USGS and Idaho Department of Water Resources scientists constructed a computer model of ground-water flow in the Spokane Valley-Rathdrum Prairie aquifer in Spokane County, Washington, and Bonner and Kootenai Counties, Idaho. More than 500,000 residents in this area use the aquifer as a source of drinking water. The primary purpose of the model is for analyzing water inflows and outflows to the aquifer, simulating the effects of future changes in ground-water pumped from the aquifer, and evaluating aquifer management strategies. Dr. Hsieh conducts research on (1) theoretical models of fluid flow and solute transport in fractured rocks with particular emphasis on characterizing the effects of heterogeneities on different scales; (2) field methods (hydraulic and tracer tests) used to characterize the flow and transport properties of fractured rocks; and (3) the use of geological, geophysical, and geochemical methods in conjunction with hydraulic and tracer tests to model fluid flow and solute transport in fractured rocks. The seminar was part of the USGS's biweekly Water Resources Discipline Research Seminar Series. A streaming video of the seminar is available.
