This article investigates the determinants of flood risk perceptions in New Orleans, Louisiana (United States), a deltaic coastal city highly vulnerable to seasonal nuisance flooding and hurricane-induced deluges and storm surges. Few studies have investigated the influence of hazard experience, geophysical vulnerability (hazard proximity), and risk perceptions in cities undergoing postdisaster recovery and rebuilding. We use ordinal logistic regression techniques to analyze experiential, geophysical, and sociodemographic variables derived from a survey of 384 residents in seven neighborhoods. We find that residents living in neighborhoods that flooded during Hurricane Katrina exhibit higher levels of perceived risk than those residents living in neighborhoods that did not flood. In addition, findings suggest that flood risk perception is positively associated with female gender, lower income, and direct flood experiences. In conclusion, we discuss the implications of these findings for theoretical and empirical research on environmental risk, flood risk communication strategies, and flood hazards planning.
本文调查了美国路易斯安那州新奥尔良市（New Orleans, Louisiana）洪水风险认知的决定因素。新奥尔良是一个易受季节性滋扰洪水和飓风引发的洪水及风暴潮影响的三角洲沿海城市。很少有研究调查过在经历灾害后恢复和重建的城市中，灾害经历、地理物理脆弱性（灾害临近度）和风险认知的影响。我们使用有序逻辑回归技术，分析了从七个街区的 384 名居民调查中得出的经验、地理物理和社会人口变量。我们发现，与那些居住在没有被洪水淹没的街区的居民相比，居住在卡特里娜飓风期间被洪水淹没的街区的居民表现出更高水平的风险感知。此外，研究结果表明，洪水风险感知与女性性别、较低收入和直接洪水经历呈正相关。总之，我们讨论了这些发现对环境风险、洪水风险沟通策略和洪水灾害规划的理论和实证研究的意义。
