WATER LEVEL STATISTICS FOR DESIGN OF TRANSPORTATION FACILITIES IN COASTAL LOUISIANA

Results are presented of an effort to provide up-to-date information about hurricane flood water level statistics for coastal Louisiana that reflect present landscape conditions and to enable flood elevations to be easily updated in the future. The water level statistics presented are based on a hydrodynamic computer model to compute the threat of hurricane flooding within the coastal zone of Louisiana. Hydrodynamic models of flooding are currently used to determine flood water levels in rivers and channels. The hydrodynamic model used in this study is the overland flooding model of the Federal Emergency Management Agency, the same model used to compute the base flood elevations for the National Flood Insurance Program. The model has been modified to make it operate more easily on a microcomputer. The latest topographic data and hurricane statistics were used in the study.
