WebThe FSR/FEH rainfall-runoff method is a UK-based tool for design flood estimation often used alongside statistical methods for flood frequency analysis where estimates of complete flood hydrographs and flood volumes are required. The method was first documented in the Flood Studies Report (FSR) in 1975 (NERC, 1975) and further refined ... WebOverview. As discussed in this guidance document, latest research has shown that FEH methods are more accurate than methods such as IH124 for estimating peak flows within small catchments and for conducting plot scale greenfield runoff calculations.
