The staff will evaluate the flood event duration parameters (including warning time and period of inundation) and flood associated effects during its review of the MSA.Note 4: ce-induced flooding is bounded by the seismically induced dam failure hazard. Therefore, the maximum water surface elevation reported in this table for this ice-induced flooding is the same as for seismically induced dam failure.
