FEWS-Risk Analysis tool Until today, real time flood forecasting has been traditionally deterministic. Emerging data sets and approaches offer the opportunity to take this further to offer end users an understanding of the probability or likely consequences of flooding. HR Wallingford and Deltares are working on a collaborative project to develop the FEWS-Risk Analysis tool which will bring improved decision support for disaster risk reduction. The tool will help to answer questions such as: • What type of action can I take to mend a weak spot in my flood defences? • Where should I enforce my flood defence system? • Which areas should I evacuate first? Interested? Joint collaboration and development Deltares and HR Wallingford will share their knowledge and models within this study, and will also work together on the development of the application and pilot projects. By building the FEWS-Risk Analysis tool, we bring synergy in the use of flood risk modelling tools for flood risk management and flood event management. Existing tools from Deltares and HR Wallingford will be put in an operational framework. The tool will couple a 1D river channel, a dynamic breach growth model, a 2D inundation model and an impact model under the Delft-FEWS shell. We will take care that the way we set up the FEWS-Risk Analysis is flexible and re-usable. Furthermore, we will put effort into keeping the tool computationally efficient in order to make it suitable for operational use. We would like to develop this tool together with end-users in order understand the requirements of such a tool. We would like to use your experiences and ask for your opinion on how you might use the type of information that these new tools can provide, so that we can develop the tools to become of most use to end users such as yourselves.
