虽然以前的研究经常发现洪水在传统的洪水风险区域之外的影响，比如联邦应急管理局的100年洪泛区地图，但我们对洪泛区之外经历这些影响的地区的社会和人口构成的了解较少，尽管在美国，洪水风险和影响的社会不平等更广泛地记录在案。利用100年洪泛区、洪水影响、社会人口特征和住宅地块的数据，本研究将种族作为社会空间不平等的主要标志，以检查大休斯顿地区哈维飓风期间洪泛区内外的洪水。描述性研究结果表明，绝大多数洪水发生在百年洪泛区以外。回归模型显示，虽然在洪水风险方面存在种族不平等的证据有限，但在“哈维”飓风期间，洪水范围存在实质性的种族不平等。结果进一步表明，这些洪水范围的总体种族不平等主要是由发生在100年洪泛区以外的影响造成的。结论集中在洪水风险的传统描述如何以及为什么会低估自然灾害的种族不平等。
While previous research often finds flood impacts outside of conventional flood risk zones such as FEMA’s 100-year floodplain maps, we have less of a sense of the social and demographic composition of the areas outside of floodplains that experience these impacts, even though social inequalities in flood risk and impacts more broadly is well-documented in the United States. Using data on 100-year floodplains, flood impacts, socio-demographic characteristics, and residential parcels, this study focuses on race as a primary marker of socio-spatial inequality to examine flooding inside and outside of floodplains during Hurricane Harvey in Greater Houston. Descriptive findings show that a large majority of flooding occurred outside of 100-year floodplains. Regression models show that while there is limited evidence of racial inequalities in flood risk as conceptualized as location in 100-year floodplains, there are substantial racial inequalities in flood extent during Hurricane Harvey. Results further show that these overall racial inequalities in flood extent are primarily driven by impacts that occurred outside of 100-year floodplains. Conclusions center on how and why conventional delineations of flood risk can underestimate racial inequalities to natural hazards.
