Levee and floodwall seepage models based on two-dimensional (2D) conditions can underpredict landside vertical hydraulic gradients and uplift pressures due to excavations and convex bends. The Sherman Island levee system is used to calibrate a three-dimensional (3D) seepage model to evaluate the eff...
