Abstract: The risk of overtopping can be significant for flood control levees or floodwalls, and the consequences can be costly and potentially catastrophic. Designs using superiority can force initial overtopping in the least hazardous location. Water surface profiles above the design profile need examining to apply superiority. Documenting overtopping consequences in the protected area is helpful for a flood hazard plan. A local flood warning system can be beneficial to the plan.
