Katrina E. Bennett from Los Alamos National Laboratory will present "Changing extreme streamflow patterns in boreal forest watersheds of Alaska" on Tuesday, 23 June at 10:00 am AKDT.
The Interior discontinuous permafrost zone of the boreal subarctic represents one of the largest ecosystems on earth and is vastly understudied with respect to changing hydrologic extreme events. The first part of this presentation will focus on recent research results for snowmelt and glacially dominated Interior Alaska river basins for the past 50/60 years (1954/64-2013).
The second part of this presentation will present projections of future extreme streamflow changes in a snowmelt dominated basin of the Tanana River, a sub-watershed to the Yukon River system, using six global climate models, two emission scenarios, two hydrologic models and two different time periods. Projections for temperature, precipitation and streamflow will be discussed, with a focus on changing peak flows events, and return intervals.
Pre-registration for webinars is strongly encouraged. The audio portion of the call is through a toll-free phone line and the slide presentation is streamed via computer.
