摘要虽然人口密度可以改变一个社区的总体用水需求，但社会经济的变化可以改变每日高峰用水需求的时间分布。本研究旨在确定这两种类型的人口动态对水系统的运作的影响的比较关键性的压力测量。这项研究专门评估了与高收入人口增加和密度变化相关的中产阶级化情景。研究人员使用美国中产阶级城市现有的供水系统对中产阶级化场景进行了水力模拟。结果表明，在中产阶级化的城市，如波特兰和明尼阿波利斯，社会经济变化的影响可能是可以忽略不计的密度变化相比。然而，在华盛顿和亚特兰大等中产阶级化的城市，社会经济的变化不容忽视。鉴于中产阶级化等人口动态的复杂性，我们建议决策者仔细评估这些动态，以增强城市的韧性。
ABSTRACT While population density can change the overall water demand of a neighborhood, socioeconomic shifts can change the temporal distribution of daily peak demands. This study seeks to determine the comparative criticality of the impacts of both types of population dynamics on the operations of a water system—as measured by pressure. This study specifically assesses scenarios of gentrification, associated with increases in higher-income populations and density changes. Researchers carried out hydraulic simulations of gentrification scenarios using an existing water system in a gentrifying U.S. city. The results indicate that in gentrifying cities such as Portland and Minneapolis, the impact of the socioeconomic shifts may be negligible when compared that of density changes. In gentrifying cities such as Washington D.C. and Atlanta, however, socioeconomic shifts cannot be overlooked. Given the complexity of population dynamics such as gentrification, we recommend decision-makers to carefully assess these dynamics to enhance urban resilience.
