Abstract: This study investigates climate change effects for severe rainfall events and its implications to urban drainage design and management. Canal de Isabel II, managing the whole water cycle in the Madrid Region, aims to reach a better understanding of a changing future by adjusting design and modeling parameters for urban drainage systems. The study calculates climate change factors for three key meteorological stations using the latest CMIP6 findings. These factors can be incorporated into Canal de Isabel II extensive urban drainage models to ensure updated outputs. The methodology includes downscaling techniques to adapt General Circulation Models to small watersheds to obtain precise parameterization of short-duration rainfall. By analyzing variability in future rainfall events, Canal de Isabel II can anticipate risks and have a better guidance on infrastructure investment.
