“…Over the past 100 years, several floods have been occurred in the city including the flood of 1961 with $ 3.25 million and the flood of 1974 with $ 8.3 million damages (Wilson 1964;US Army Corps 1983). Hattiesburg underwent the most flood damage, in part due to its size.…”

The purpose of this study is risk analysis in optimum design of a composite multi-section flood control levee system along a river reach considering several uncertainties, and assessing the coordination between the system and its individual components. A stochastic optimization model was developed in which Latin Hypercube sampling and Cholesky decomposition was used for quantifying uncertainties. The results indicated that the multi-section model is more cost-effective than a single-section in such a way that total cost of developing system was reduced by 38%. It was also found that with the increase of the complexity of the model (one and multi-section), and with the separation of uncertainties (into epistemic and aleatory), the coordination of the system decreases 130% and 30% respectively. Finally, it was found that lower and upper tails of a component histogram may be completely differ from a fitted distribution.

“…1). Damage costs not adjusted for inflation within the cities of Hattiesburg and Petal were reported to be $3.25 million (Wilson, 1964) Introduction from which current or historical water levels (stage) can be obtained. A third source is the National Weather Service's (NWS) forecast of peak stage at the USGS gage through the Advanced Hydrologic Prediction Service (AHPS) site.…”

Conversion Factors and Datums Horizontal coordinate information is referenced to the North American Datum of 1983 (NAD 83).Elevation, as used in this report, refers to the distance above NAVD 88.Stage, as used in this report, is the height of the water surface above an arbitrary datum established at the gage (gage datum). AcknowledgmentsThe author wishes to thank the many local, State, and Federal agencies that have cooperated in the funding for the operation and maintenance of the gages used for this study, especially the Mississippi Department of Environmental Quality. Special thanks are given to the City of Hattiesburg, City of Petal, Forrest County, Mississippi Emergency Management Agency, Mississippi Department of Homeland Security, and the Emergency Management District for their cooperation in this study and to the National Weather Service for their continued support to the USGS flood-inundation mapping initiative. In addition, the infor mation has been provided to the National Weather Service (NWS) for incorporation into their Advanced Hydrologic Prediction Service (AHPS) flood warning system (http:/water.weather.gov/ahps/). The NWS forecasts flood hydrographs at many places that are often colocated with USGS streamgages. NWS-forecasted peak-stage information may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation.In this study, flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The model was calibrated by using the most current stage-discharge relations at the Leaf River at Hattiesburg, Miss. streamgage (02473000) and documented high-water marks from recent and historical floods. The hydraulic model was then used to determine 13 water-surface profiles for flood stages at 1.0-foot intervals referenced to the streamgage datum and ranging from bankfull to approximately the highest recorded water level at the streamgage. The simulated water-surface profiles were then combined with a geographic information system (GIS) digital elevation model (DEM, derived from light detection and ranging (lidar) data having a 0.6-foot vertical and 9.84-foot horizontal resolution) in order to delineate the area flooded at each water level.Development of the estimated flood inundation maps as described in this report updat...
