The findings from the case study have informed the House of Commons Environment, Food and Rural Affairs Select Committee inquiry into flooding. The research received the full collaboration of the staff and elected members of the Local Authority, the sewage undertaker United Utilities, officers of the Environment Agency, and in particular the local residents who experienced the flooding. Researchers attended local community meetings as participant observers in the aftermath of the 2006 flood. The outputs will be integrated in to the findings of the wider ERA-Net CRUE collaborative research project. The findings will be presented at flood risk management conferences and meetings (FLOODrisk 2008, COST C22) and will be reported in peer reviewed academic journals (Journal of Flood Risk Management).


(i) To identify the efficiency of various methods of flood information in raising stakeholders` risk awareness and readiness for appropriate response in urban areas. (ii) To explore the opportunities and limitations of non-structural measures for flood mitigation in small urban catchments. (iii) To assess the effectiveness of physical and ecological modifications to drainage systems (from green roofs to channel changes) in managing the risk of flooding in urban areas. (iv) To assess the social, economical and environmental effectiveness of non structural measures in managing flood risk in developed urban areas. KEY


The project will contribute to our understanding of the causes and solutions to flooding from small, often hidden, urban rivers and streams, and therefore improve the evidence base for the most effective way to manage such small urban catchments. In heavily urbanised catchments the scope is potentially more limited for non-structural responses to manage flooding, but there may be some useful opportunities through good urban design and increased risk awareness. This project will develop a methodology for the effective application of non-structural solution to flooding in urban environments. The results should be of value to urban planners, regulators and water companies. They will provide regulators with a planning framework and may influence the investment decision of local authorities and water companies with asset management responsibilities.
