Storm surge above the levee crest elevation combined with levee wave overtopping can place large shear stresses on the levee landward slope face. Previous research has examined overtopping flow conditions, but the resulting shear stress has not been thoroughly analyzed. The purpose of this thesis is to examine multiple combinations of overtopping flow conditions and the resultant shear stress along the levee’s landward slope. This thesis presents measurements of depth, velocity, discharge, and wave height, and it estimates shear stress using data collected from a scaled physical model. Shear stress is estimated using three equations including a version of Saint-Venant equations that accounts for unsteady, non-uniform flow. The objective of this thesis is to develop shear stress estimates on the landward slope of a levee during combined wave and surge overtopping for conditions and dimensions typical to levees along the Gulf coast of the United States.
