For the Barcelona Case Study, a 1D/2D-coupled flood model that utilizes the dual drainage concept [17] using Infoworks ICM (Intergrated Catchment Modelling) [18] has been employed. This hydrodynamic model was used to provide outputs of both water depths and velocities for different return periods under the present (Baseline) and Future Climate Change scenarios whereby a Business As Usual (BAU) policy is assumed (i.e., no adaptation measures applied within the city). For the climate change scenarios in Barcelona, a Representative Concentration Pathway of 8.5 (RCP8.5) has been considered. Table 1 shows the comparison of the maximum rainfall intensities for the Baseline and BAU scenarios from the synthetic rainfall events generated via the Foundation for Climate Research (FIC) used within the flood model.
