Abstract:Transportation facilities in the coastal zone of Louisiana, such as roadways, bridges, and ports, are subject to flooding which must be considered in the design, operation, and maintenance of these facilities. Flooding can result from hurricanes, tidal action, run-off, backwater, and combinations of these events. This report presents the results of a study to determine the hurricane flood elevations in coastal Louisiana which represent average return intervals of 10, 25, 50, 100, and 500 years. Since flood water level statistics are changing in coastal Louisiana due to dredging of channels, levee construction, sea level rise, wetland loss, and subsidence, this study also establishes within LaDOTD the capability for assessing future risk.
