The project will develop a methodological framework for flood management in small urban catchments. Based on case studies of urban river catchments of the cities Hamburg, Manchester, Bradford, Glasgow, Cologne, Dresden and Paris the effectiveness and efficiency of non-structural measures to reduce flood damage will be analysed and evaluated. On this basis the feasibility of assessing and mitigating flood risk from hidden watercourses and associated culverts in urban areas will be illustrated and possibilities and ways to implement effective, non-structural solutions to minimise flooding from these sources will be demonstrated. Finally the value of “daylighting” urban streams by removing culverts and restoring open channels that include space for flood storage will be shown.
Due to the sealed surface and compact, often hidden channels only little retention exists in small urban catchments. Heavy rain will produce flush floods even in flat areas.
What are the chances of non-structural measures under these extreme hydrological conditions?
What is the right strategy of flood risk management in these catchments? Can SUDS and daylighting of culverts reduce the probability of flood?
What risk awareness exists at stakeholders and how can it be improved?

From Information to Learning = Interactive Learning Groups
Actions and Applied Methods
inventory of each city’s hydrological and urban situation (flood risk, flood risk management plan, regulatory, societal, cultural and economic data).
Focus groups and interviews will be conducted to determine people’s flood risk awareness and readiness to live with floods (their risk culture).
By applying the interactive learning group method, the stakeholders will be tested on their capability and openness to apply soft mitigation methods and non-structural measures
Non-structural measures will be systemised and evaluated in their efficiency to raise risk awareness and to develop efficient flood risk management plans for urban catchments with rapidly rising floods
