SUMMARY:Webinar: What’s in a Snow Model? A Four-Decade Legacy of iSnobal Development
DESCRIPTION:Presenter(s):\nAndrew Hedrick (USDA-NWRC)\nSeminar Date:\nSep 22\, 2026\n\nAbout the Talk:\n\niSnobal is an energy and mass balance snow model that has grown over the last four decades from a simple research tool into an operational basin scale system for estimating how much energy and water are stored in our mountain snowpack. Its design has always focused on efficiency\, accurate physics\, and flexibility in the weather forcing data it uses. Recent updates have modernized the code\, improved numerical stability\, and refined how the model handles radiation and turbulent energy exchanges. Importantly\, for operational adoption\, the user experience has also improved through easier installation\, automated setup\, and standalone tools for developing forcing data from weather stations or forecast models. These upgrades allow new sensitivity studies\, estimation of model uncertainty\, and real-time decision support applications. Ongoing work is to incorporate next generation remote sensing data and improve how the model accounts for snow darkening from light absorbing particles and interactions between vegetation and snow. Further improvements on the horizon include leveraging machine learning methods to automate parameter selection and better connect iSnobal with hydrologic routing models. All of these advancements aim to broaden operational adoption and improve the accuracy of snowpack characterization\, strengthening water resource prediction for reservoir operations\, flood forecasting\, drought mitigation\, and seasonal allocation in snow-dominated basins throughout Idaho and the West. \n\nAbout the Speaker:\n\nAndrew is a Research Hydrologist at the USDA-ARS Northwest Watershed Research Center in Boise where he studies the hydrology of snow-dominated mountain catchments and manages the snow measurement and modeling program at the Reynolds Creek Experimental Watershed in Owyhee County. He has been a researcher with USDA-ARS since 2014\, receiving a Geophysics M.S. in 2013 and a Geophysics PhD in 2018\, both from Boise State University working with Dr. Hans-Peter Marshall and Dr. Danny Marks. \nZoom Link\nMeeting ID: 865 7192 8806\nPasscode: 1234

SUMMARY:Webinar: The Ultimate Geologic Sponge: Volcanic aquifers and their outsized importance in the future of water in the West
DESCRIPTION:Presenter(s):\nGordon Grant (USFS)\nSeminar Date:\nSep 29\, 2026\n\nAbout the Talk:\n\nIn young volcanic landscapes\, thick sequences of basalt flows create groundwater aquifers that store prodigious volumes of water. Drawing on over 30 years of research in the central Oregon Cascades\, this talk will explore the hydrogeology\, geomorphology\, and landscape evolution of young volcanic provinces and their critical importance for provisioning summer streamflow in the western United State. Parallels with the Idaho Snake River Plain will be explored. \nFor those in Boise\, join us in person at the IDWR offices\, Room 602 C/D\, 322 E Front St\, Boise\, ID 83702 \n\nAbout the Speaker:\n\nGordon Grant is a Courtesy Professor in the College of Earth\, Ocean\, and Atmospheric Sciences at Oregon State University and Emeritus Research Hydrologist with the USDA Forest Service PNW Research Station. His involvement with rivers began as a decade-long career as a whitewater river guide on western US rivers. He received his Ph.D. in fluvial geomorphology from Johns Hopkins University in 1986\, and began work for the research branch of the U.S. Forest Service with the overarching goal of advancing understanding of how stream networks\, watersheds\, and entire landscapes respond to changes in streamflow\, sediment transport\, and wood entrainment. In particular\, this research has focused on fluvial responses due to land use\, dams and dam removal\, volcanic eruptions\, and climate change in the Pacific Northwest and beyond. He is a Fellow of both the American Geophysical Union and the Geological Society of America\, and former President of the Earth and Planetary Surface Processes (EPSP) Section of AGU. He is the recipient of the Distinguished Career Award of the Quaternary Geology and Geomorphology Section of GSA\, and the G.K. Gilbert Award of the EPSP Section of AGU. \nResearch group website at wpg.forestry.oregonstate.edu \n\nPresentations will be recorded and made available after the presentation\, unless otherwise requested by the presenter.
