FEH is a CEH publication, giving guidance on rainfall and river flood frequency estimation in the UK. Flood frequency estimates are required for the planning and assessment of flood defences, and the design of other structures such as bridges, culverts, and reservoir spillways. There is an increasing demand for estimates that can form the base for flood risk maps, important in the planning of new developments. The FEH also provides methods for assessing the rarity of notable rainfalls or floods, which are of interest to insurers and others. The procedures are clearly explained, and supporting theory and results included. The FEH is issued in a set of five printed volumes reprinted in 2008.
