This report presents the results of a major project to develop a new statistical model of point rainfall depth-duration-frequency (DDF) for the UK, to replace the current Flood Estimation Handbook (FEH) DDF model. The new model was constructed for estimating rainfall depths falling over durations ranging from 1 hour to 192 hours (8 days) for return periods ranging from 2 years to 10,000 years, but in many locations it is capable of producing indicative estimates for higher return periods, up to 100,000 years.
