在美国所有的自然灾害中，洪水继续对人类社会的财产和安全构成最大的威胁。本研究考察了德克萨斯州建筑环境与洪水影响之间的关系，该州一直是美国其他州遭受洪水破坏最多的州。具体来说，我们计算了1997 - 2001年间423次县级洪水造成的财产损失。我们确定了几种建筑环境措施的影响，包括湿地改造、不透水地表和水坝，在控制生物物理和社会经济特征的同时，对报告的财产损失进行了影响。统计结果表明，自然形成的湿地在减轻洪水破坏方面发挥着特别重要的作用。这些发现为规划人员和洪水管理者提供了指导，指导他们如何最有效地减轻社区一级洪水造成的代价高昂的影响。
Floods continue to pose the greatest threat to the property and safety of human communities among all natural hazards in the United States. This study examines the relationship between the built environment and flood impacts in Texas, which consistently sustains the most damage from flooding of any other state in the country. Specifically, we calculate property damage resulting from 423 flood events between 1997 and 2001 at the county level. We identify the effect of several built environment measures, including wetland alteration, impervious surface, and dams on reported property damage while controlling for biophysical and socio-economic characteristics. Statistical results suggest that naturally occurring wetlands play a particularly important role in mitigating flood damage. These findings provide guidance to planners and flood managers on how to alleviate most effectively the costly impacts of floods at the community level.
