About the Project

In the MUFFIN project, we will set up “test benches” in Ålborg, Helsinki, Rotterdam and Stockholm to explore  different ways to forecast floods in urban basins and answer three categories of questions:

  • The rainfall forecast: What is the impact of resolution in time and space? Which types of forecasts are most suitable? What accuracy is attainable with respect to time, place and intensity of short-duration extremes?
  • The hydrology/hydraulics model: What are the different characteristics in terms of surface and sub-surface information required, resource demand for model set-up and calibration, computational power, etc.? What accuracy is attainable with respect to time, place and intensity of short-duration extremes?
  • The end user value: How early must a flood alert be issued, and with what spatial level of detail to be useful for different end-user categories? What is the value of large-scale forecasts in cities that lack a local forecasting system?

A key intention behind the consortium is to bridge the gap between the urban and large-scale hydrological modelling communities. Generally, research groups as well as engineering practitioners are specializing in one community or the other. However, it is important to join forces to develop innovative solutions to diminish the adverse effects of urban flooding. The project will generate new joint knowledge and understanding of:

  • Small-scale rainfall extremes, their space-time characteristics and predictability
  • Possibilities and limitations of urban flood forecasting systems at different scales
  • The relationship between the properties of the forecasting system and the end-user value

The knowledge gained and experiences made will be important for future development of urban flood forecasting systems. The local systems may serve as role models for other cities and the large-scale system will be useful for cities lacking the resources to develop a local system. The outcome will be improved early warnings for floods in urban areas and thus a safer and more climate-proof society.

The project will build heavily on previous related EU research projects and other activities, including RAINGAIN, Baltrad/+ and OPERA. E-HYPE has been involved in several EU-projects and is being tested for inclusion in the European Flood Alert System (EFAS).
