This Urban Flood Risk Handbook: Assessing Risk and Identifying Interventions is a roadmap for conducting an urban flood risk assessment in any city in the world. It includes practical guidance for a flood risk assessment project, covering the key hazard and risk modeling stages as well as the evaluation of different flood-mitigating infrastructure intervention options and management of the project. The Handbook has been developed based on lessons learned from implementing urban flood risk assessments around the world in a diversity of contexts. It is intended for a wide variety of practitioners: project managers, city officials, and anyone else interested in conducting a strategic study of a city’s flood risk and developing potential solutions for it.

We expect this Handbook to contribute to the understanding of urban flood risk, make this specialized knowledge more accessible to a wider public, and support the process of building cities that are not only capable of withstanding floods but also provide safe, inclusive, and sustainable environments for all their residents.
