 FUTURE–DRAINAGE will use outputs from the new UKCP18 perturbed physics convection–permitting model (CPM) ensemble (at 2.2km resolution across the UK) to produce revised rainfall ‘uplifts’, the first assessment of uncertainty in rainfall ‘uplifts’ and new guidance for UK urban drainage design and urban flood risk assessment for use in climate adaptation. This will include the development of a new regional pooling approach for spatially–correlated CPM outputs, and modelling to compare the national RoFSW methodology to outputs from fully–hydrodynamic urban flood models, for the same cities and uplifts, to quantify the uncertainty in and determine the level of detail in modelling needed for future urban flood predictions.
