Groundwater and Heat Flow in the Northwest Volcanic Province, U.S.A. Implications for Geothermal Energy Development
Erick R. Burns, US Geological Survery
Heat-flow mapping of the western USA has identified apparent low-geothermal-heat-flow anomalies within the ~500,000 km2 Northwest Volcanic Province (NVP). The largest of the contiguous heat-flow anomalies are generally coincident with the Eastern Snake River Plain (ESRP) aquifer and the Columbia Plateau Regional Aquifer System (CPRAS), and these apparent low- heat-flow anomalies have been shown to be the result of measurement bias due to advection of heat by groundwater. The ESRP, the CPRAS, and the new USGS Northwest Volcanic Aquifer Study Area (NVASA) comprise most of the NVP, an area that contains over half of Meinzer’s high-volume springs of the U.S. (Meinzer, 1927) and much of the nation’s estimated but unproven geothermal electricity-production potential. While the ESRP and the CPRAS have been the subject of prior systematic groundwater study, the NVASA is largely uncharacterized, though it is encircled by a range of volcanic terrains with existing USGS models. The variation in volcanic hydrology across the NVP will be summarized, with an emphasis on physical mechanisms controlling groundwater and heat flow. Implications will be developed intuitively and quantitatively for water resources, habitat (especially, thermally sensitive groundwater-dependent ecosystems), and heat flow/geothermal energy development.
Erick Burns is a research hydrologist with the USGS Oregon Water Science Center. His research experience is varied, including groundwater flow and transport, geothermal energy, geostatistical methods and stochastic analysis, process thermodynamics, agricultural water pollution, and seawater intrusion. Additionally, Erick has taught hydrology and geostatistics courses.
