Research Webinar: Integrating Terrestrial, Snowpack, And Meteorological Drivers Of Runoff Generation During Winter Thaws In A Montane Catchment Of The Northeastern U.S.
Join Lake Champlain Sea Grant and Garnet Williams, MS student studying geology at ¶¶Òõ̽̽ for our final Spring Research Webinar to discuss winter runoff patterns in Vermont. Over the past century, winter temperatures and precipitation falling as rain relative to snow have increased in the northeastern U.S. Winter warming has led to more frequent and intense mid- winter thaw and rain-on-snow events that often trigger extreme hydrologic response. Given that these events occur during winter when there tends to be less watershed monitoring and field activity, much remains to be understood regarding runoff generation mechanisms in montane watersheds found in the northeastern U.S. Over two successive winters, we analyzed the combinations of soil (e.g. moisture and temperature), meteorological (rain amount and intensity, air temperature), and snowpack (depth, ripeness) conditions that enhance or diminish runoff response during winter thaw events. This analysis of high-frequency soil, snow, meteorological and hydrologic properties provides unique insight that is needed to quantify, manage, and mitigate increasingly common disturbances due to changing winter conditions.
Participants should expect approximately 30 minutes of presentation, which will be recorded, followed by a facilitated, 30-minute Q&A period.
