城市特别容易受到暴雨-持续时间短、强度大的降雨事件-的影响,而传统的雨水和洪水管理政策往往不能充分解决这一问题。气候变化预计将增加许多城市的暴雨频率和强度。随着小暴雨事件变得更加频繁,极端事件变得更加严重,城市将需要迅速改造其雨水排放和相互依赖的系统,以及指导其基础设施决策和政策的知识系统。在本文中,我们讨论了知识系统的演变,以应对这些挑战,使用三个不同的城市(凤凰城,美国;哥本哈根,丹麦;和纽约市,美国)作为案例研究。我们发现城市之间的合作伙伴关系--甚至跨越国界--可以成为暴雨知识系统的一个特别重要的组成部分。我们还确定了与非平稳气候相关的知识系统的局限性,私有财产的脆弱性和综合水资源管理中暴雨基础设施的代表性,这为未来的研究提供了机会,以支持决策。
Cities are particularly vulnerable to cloudbursts - short-duration, intense rainfall events – which are often inadequately addressed through conventional stormwater and flood management policy. Climate change is projected to increase the frequency and intensity of cloudbursts in many cities. As minor cloudburst events become more frequent and extreme events more severe, cities will need to rapidly transform their stormwater drainage and interdependent systems, and the knowledge systems that guide their infrastructure decisions and policy. In this paper, we discuss the evolution of knowledge systems to address these challenges, using three diverse cities (Phoenix, USA; Copenhagen, Denmark; and New York City, USA) as case studies. We found that partnerships between cities – even across national boundaries – can be a particularly important component of cloudburst knowledge systems. We also identified limitations in knowledge systems related to non-stationary climate, the vulnerability of private property and the representation of cloudburst infrastructure in integrated water management, which present opportunities for future research to support decision-making.
