In order to simulate failure of a dam and estimate the impacts of the resultant flood wave, stage-storage information for the full depth of the reservoir is required. This can often be obtained from historical design or construction records. If significant changes to storage are anticipated due to sedimentation or other causes, bathymetric survey can be used to develop updated stage-storage information for the reservoir.
