This page describes the outputs from the research project (FD1913) 'Revitalisation of the FSR/FEH rainfall-runoff method' funded through the Joint Defra/Environment Agency Flood and Coastal Erosion Risk Management R&D Programme. The research was carried out by CEH during the period 2001-2005. One of the outputs is a supplementary report to the Flood Estimation Handbook. A new lumped conceptual rainfall-runoff model, the Revitalised Flood Hydrograph (ReFH) model, has been developed for modelling flood events. The ReFH model is based on robust hydrological modelling techniques and is considered to be an improvement over the existing FSR/FEH model. It enables a more direct and transparent description of flood-generating mechanisms and introduces the concept of seasonal variation in soil moisture content, design rainfall and baseflow.
