Assessment of the resilience of Barcelona urban services in case of flooding. The RESCCUE project

Within the framework of the European RESCCUE Project, climate projections for the city of Barcelona show significant increases in maximum rainfall intensities for the 2071-2100 horizon. This paper presents the evaluation of the resilience of urban services in the city against flood episodes for current and future rainfall conditions. The use of sectorial and integrated models allows to assess the response of the city’s drainage system both at the underground sewer system level and at the surface level by analyzing the hydraulic behavior of all urban surfaces (streets, squares, parks, etc.). On the other hand, the parameters associated with surface flooding (extension of flood areas, flow depth and velocity) can be used to estimate potential impacts on other strategic urban services such as surface traffic, the electrical system and the waste collection service.
