This document summarizes the CORFU project, which aims to assess flood impacts and develop flood resilience measures for European and Asian cities. It describes the flood damage assessment tool developed as part of CORFU to efficiently evaluate flood damage and expected annual damage. The tool uses standard GIS data formats and can integrate with hydraulic modelling software. It calculates damage to individual buildings based on flood depth data, land use types, and depth-damage curves. The document demonstrates the tool's use for a case study in Dhaka and concludes the tool can evaluate flood damage under different scenarios to help create more flood resilient cities.
