3. Surges: The staff reviews historical storm surge data and accompanying hydrometeorological conditions obtained from NOAA to evaluate flooding potential from storm surges at the site. In order to establish the design-basis flood water elevation, the staff evaluates the PMH and associated storm surge at coastal sites, wind-waves caused by PMH winds translated to inland sites, and combination of less severe storm surges with runoff-induced floods. A detailed review of surge mechanisms and estimation of design-basis events is carried out in SER Section 2.4.5. 4. Seiches: The staff reviews historical data from USGS and NOAA to evaluate the potential effect of seiche activity in the vicinity of the site. In order to establish the design-basis flood water elevation, the staff evaluates and estimates the most severe seiche activity caused by atmospheric and seismic forcing. Less severe seiche activity may be combined with runoff-induced floods and storm surges to evaluate the design- basis flood elevation. A detailed review of seiche mechanisms and estimation of flood water elevation due to seiche activity is performed in SER Section 2.4.5. 5. Tsunami: The staff reviews historical data from USGS and NOAA to evaluate the potential effects of flooding due to tsunami at the site. Both near and far-field sources including seismic and submarine landslides are reviewed for coastal sites. Hillslope failure and sub-aerial landslide-generated tsunami-like waves are also reviewed if applicable for the site. In order to establish design-basis flood water elevation, the staff evaluates and estimates flooding from a probable maximum tsunami. A detailed review procedure for review of tsunami hazards is described in SRP Section 2.4.6 and is carried out by the staff in SER Section 2.4.6. 6. Seismically Induced Dam Failures (or Breaches): The staff reviews historical data from USGS, USACE, and the Bureau of Reclamation to evaluate potential flooding at the plant site due to seismically
