Improved understanding of fluvial streambank erosion mechanics will be developed from ongoing studies along two sites on the Clear Creek watershed, Iowa. At the two sites data are continuously collected that comprise both driving and resisting forces, such as bank topography, bank erosion rate, flow field, and boundary material properties. These data will be used to determine a relationship between fluvial bank erosion rate and those factors controlling bank erosion, which will then be incorporated into the CONCEPTS streambank erosion algorithms. The enhanced fluvial streambank erosion algorithm will be utilized in sediment source assessments.
