洪水常常造成毁灭性的后果。了解这些风险随着气候变化的演变是很重要的。市政基础设施的设计使用的历史数据不再准确地代表当前的气候条件，这表明基础设施可能表现不佳。本研究的目的是将Bowering等人（2013）提出的一种新方法应用于加拿大安大略省伦敦市气候变化引起的洪水风险评估。从气候、水文和水力分析中得出的洪泛区地图为风险评估程序提供了直接的输入。在两种气候和两种水力情景的表格和地图中确定了被淹没的基础设施和高风险区域。结果表明，最关键的洪水情景是100年气候变化的上限，高风险是由位于洪泛区的昂贵基础设施驱动的。研究结果可作为气候变化适应政策制定和应急管理的支持。
Flooding often has devastating consequences. It is important to understand the evolution of these risks as climate changes. Municipal infrastructure is designed using historical data that no longer accurately represents current climate conditions, indicating infrastructure may underperform. The purpose of this study is to apply a new methodology for the assessment of climate change caused flood risk by Bowering et al. (2013) to the City of London, Ontario, Canada. Floodplain maps derived from climate, hydrologic and hydraulic analyses provide direct input into risk assessment procedure. Inundated infrastructure and high risk areas are identified in tables and maps for two climate and two hydraulic scenarios. Results indicate the most critical flood scenario is the 100 year climate change upper bound and high risk is driven by expensive infrastructure located in the floodplains. Results of the study are used as the support for climate change adaptation policy development and emergency management.
