Description :
This study identifies and assesses the controls on hydraulic erosion of cohesive riverbanks on a 600-m reach of an urban ephemeral stream with active bank erosion. The AA. examined hydraulic bank erosion by separating estimated bank shear stress into 4 properties : magnitude, duration, event peak, and variability. The results suggest that the amount of hydraulic erosion of cohesive riverbanks is dictated by flow peak intensities. Finally, a conceptual model is produced for estimating bank erosion rates based on their silt-clay content.
