Significant climate change has been observed in the cryosphere, particularly in snow-dominated watersheds in the western U.S. and Pacific Northwest (Brekke et al 2009, Karl et al. 2009). Changing coastal, glacial, ice and permafrost conditions in Alaska are well documented (ACIA, 2004). Lake and river ice impacts due to climate change in the continental U.S., though less well documented, are also impacting USACE operations. This team will compile existing literature on sea-ice coastal vulnerabilities, changing glacial conditions, altered river and lake ice regimes and climate impacts to snowmelt in the context of USACE operations. The initial effort will evaluate changes in river ice regimes with respect to published USGS statistical analyses of river ice cover in the context of USACE operations and emergency management. This information will be provided in the form of processes, methods and guidance, including the Climate Change Engineer Manual, and will provide input to other teams.
