Case studies that focus on exceedance of the design flood event and the resulting overtopping conditions may be used to provide cost-effective analysis of overtopping protection systems. For this case study, conditions of levee overtopping are evaluated for the Probable Maximum Flood (PMF), with a two dimensional flow model (FLO-2D) used to represent the flood event in a relatively flat area susceptible to flash flooding. The model calculates the duration of overtopping and the resulting flood depths and velocities. The model outputs are utilized to evaluate the effectiveness of riprap as potential overtopping protection.


Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.
