Impacts of Tropical Storm Irene on Streams in Vermont

Many streams in the parts of Vermont that were hardest hit by Tropical Storm Irene were radically altered. The changes include extensive stream bank erosion and landsliding, wholesale channel shifts, widening and downcutting of channels, and extensive debris jams. These changes have of course had dramatic impacts on roads, structures, and the lives of nearby residents. Following the storm, the cleanup and restoration efforts have resulted in additional changes in the stream systems. This presentation (produced with co-author Kristen Underwood of South Mountain Research and Consulting of Bristol, Vermont) shows preliminary information on rainfall, peak streamflows, damage to roads, and some examples of geomorphic changes in and adjacent to streams.
