This paper presents and analyzes storm surge induced flood risks along the Mississippi Gulf Coast area by demonstrating the spatial risk distribution of the study area using Geographic Information System (GIS) and statistical relationships of the risk related factors using a regression analysis Data of population census, average daily traffic, elevation of the land surface, and flood incurred property loss are collected and presented for road links and in residential blocks. Maximum surge elevation data above the North American Vertical Datum (NAVD83) are collected from a previous research that used Advanced Circulation Model software (ADCIRC) validated against representative historical hurricane wind and storm surge data collected by the Federal Emergency Management Agency (FEMA) and National Hurricane Center (NHC). Maximum surge height at a given location or block is calculated based on the existing elevations of the land surface. The statistical analyses that involve the data of direct loss coverage, population, average daily traffic, and maximum flooding inundation height of the study area reveal significant results of correlations, multicollinearity, and regression relationships. The statistical analyses also show the direct loss coverage is highly related with the maximum flooding inundation height.
