Description :
This paper describes seepage flows, soil moisture conditions, and failure mechanisms for 3 laboratory experiments on reconstructed eastern North Carolina streambanks with layered soils subject to lateral seepage. The observed failure mechanisms and measured saturation data indicated an interaction between overburden pressure, seepage forces, and bank slope on bank stability. Future bank stability modeling would benefit by incorporating lateral seepage erosion and soil liquefaction prediction calculations.
