D4.1_MUFFIN_Urban_flood_forecasting.pdf

This report provides an overview of the flood modelling development. Multi scale flood forecasting experiments are set up, tested and compared across different case study catchments, spatial and temporal scales, and with different input and forcing data, catchment characteristics, etc. The main objective is to evaluate large scale flood forecasting against local fine scale catchment flood forecasting through joint case studies. By comparing accuracy and uncertainty in critical runoff/discharge, predicted flood prone areas, potential lead-time, etc. the two model scales (hereafter referred to at the two Hydro-models) are evaluated with regards to the resolution required of inputs and outputs and their potential in real time flood forecasting in urban areas.
