Hazard and flood risk in urban areas could be significantly exacerbated due to climate change affecting future rainfall patterns, storm surge and tidal levels. This issue is one of the main concerns of the RESCCUE (RESilience to cope with Climate Change in Urban arEas – a multisectorial approach focusing on water) project, funded by the European H2020 programme. In the framework of this project, several sectorial models, simulating the operation of strategic urban services in the 3 RESCCUE cities (Barcelona, Bristol and Lisbon), have been developed and calibrated. The interdependencies and the relations among the urban sectors were also defined through the development of loosely coupled models and tools (i.e. integrated models). Specifically, for the analysis of flooding resilience, three detailed 1D/2D coupled models were performed to simulate the operation of urban drainage systems in the three sites. The outputs of these models (e.g. flood depths, surface velocity, sewer overflows, etc.) were used as input for other subsequent sectorial models (e.g. damage, transport, electricity, waste and marine water quality models) in order to assess potential services disruptions, as well as direct and indirect, and tangible and intangible flood damages. Once hazard and risk assessments for the current scenario will be completely finished, climate drivers considering climate change effects will be applied in order to evaluate their potential impacts on the RESCCUE cities resilience.
