Abstract
Katrina Flood and Contamination Mapping Track: Disaster Mangagement and Emergency Response Author(s): Gary Hecox, Amy Rose Hurricane Katrina caused wide-spread flood damage and spread contamination over much of the New Orleans area. Within 48 hours of landfall and levee failure, GIS was used, based on publicly available Internet data, to estimate extent of flooding in New Orleans and storm surge areas in Mississippi and Alabama. In New Orleans, mapped estimates of flood water depths, affected population, and impacted housing units were developed using common GIS procedures. During dewatering, daily flood water depth maps were prepared. After dewatering, EPA data was used to prepare sediment chemical concentration maps and statistics illustrating potential contamination hazard areas that may affect reconstruction and repopulation efforts. This paper demonstrates how quickly GIS can be used in the initial phases of an emergency, utilizing sparse datasets, to estimate extent of devastation and impacted population.
