Streambank erosion is recognized as one of the most important nonpoint sources of sediment and phosphorus entering streams, rivers, and lakes, and thus one of the largest contributors to the impairment of surface water quality and aquatic habitat. Funded by the UVM Water Center-US Geological Survey and Vermont Agency of Natural Resources, we have undertaken a study, which is field work intensive. Using in-situ and laboratory testing of streambank soils, continuous remote monitoring of embedded instrumentation, and transient flow and slope stability modeling, we hope to gain fundamental understanding of mechanics of riverbank instability in Vermont. This quantitative evaluation will help us understand and thus be able to predict what makes some banks stable and other banks fail over both time and changing river, groundwater and frost conditions. This research was featured on Vermont’s Channel 3 news.
