Improving flood warnings in Europe: a research and policy agenda

Abstract Warnings and emergency planning for flooding are based on the reality that no matter how thorough our investigations and flood prevention efforts through engineered structural works or land use management, some risk will always remain. This paper examines recent experience with flood warnings in the UK and continental Europe. It combines this experience with an overview of the relevant literature to identify lessons for incorporation into policy, and problem areas which would most obviously benefit from additional research. Throughout, the emphasis is on the non-engineering aspects of warning systems. Results indicate that much is being achieved in terms of the detail of warning design, but the broader issues seem to be largely ignored by both the research literature and practice. First among these broader issues is the failure, by those charged with warning system development and operation, to conceptualise the warning task as one based explicitly on the needs of those at risk. Making this happen will require the development of processes to build the necessary culture of cooperation and learning among the many organisations involved.
