New approaches to the appraisal of flood‐alleviation investment have been developed over the last twenty‐five years. This has led to (a) increased precision in benefit‐cost analysis, as better data have become available, and (b) a more rational approach to decision making as the UK Government has clarified and enhanced the decision criteria. This paper presents a detailed account of some of these developments, with an emphasis on the data on flood damages and losses avoided by flood‐alleviation schemes, and draws out lessons for those involved in this form of investment appraisal.
