Reclamation Process for Evaluating<br />
Dam <strong>Overtopping</strong> <strong>Failure</strong> Mode<br />
• Initial screening with PMF<br />
• If PMF can not be safely passed, additional flood<br />
studies are conducted<br />
• Initial flood study – flood frequency curves based<br />
on peaks and volumes<br />
• Refined flood studies – frequency flood<br />
hydrographs developed and routed<br />
• If risks are unacceptable, Corrective Action<br />
Study (CAS) is initiated<br />
• At onset <strong>of</strong> CAS, an inflow design flood is<br />
selected that will result in acceptable risks<br />
