Flood Damage Model Guidelines

Abstract

This report outlines the framework for the damage model that should be applied in the project. The intended readership of the report is project partners who will be assessing flood damage in the different case study cities. The model outlined in the report deals with direct tangible damage, and indirect tangible and intangible damage will be described in detail in other deliverables. This report outlines the general principles that should be adhered to in assessing flood damage. Recommendations are provided on the appropriate scale of modelling that should be adopted. The report then goes on to outline the categories of assets that should be considered in assessing direct tangible damage. The report also provides recommendations on the data that should be sought to estimate the value of the assets at risk and the damage functions, which relate to the characteristics of the flooding. Finally, the report concludes with recommendations on how to estimate the Expected Annual Damage. An appendix is included, which provides the technical details of the modelling tool that has been developed on a trial site in Dhaka in Bangladesh. This tool can be applied on a GIS software platform. The details of the algorithms have been provided so that they can be applied in different software packages, if necessary. The tool will be updated as further progress is made
