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 ... For drainage designs to be valid, they have to meet the no-surcharge, no-flood criteria. Pipes have to be sized adequately and effective storage solutions need to be built. ... Myth: FEH data makes models unstable. We would expect that unstable analysis is more likely to be caused by network layout rather than … See more We’ve created this handy chart to show you how the methods compare: Note that the percentage differences between FSR and FEH data will … See more This ‘heat map’ of the UK is based on a single return period, single storm duration, and single seasonal profile. The relationship between FSR and FEH data is more complex than … See more Can you use FEH data for sub-hourly events? We asked our neighbours in Wallingford – the FEH team at the Centre for Ecology and … See more The table below illustrates the difference in peak rainfall intensity predicted between FSR and FEH for Oxford, UK for a 60-minute, summer storm. See more WebThe FEH catchment descriptor methods are applicable to catchments no smaller than 0.5 kms (50 ha). The accuracy of QMED calculated from the above catchment descriptors may be significantly improved through data transfer from donor catchments. This technique is described in detail in FEH volume 3, chapter 4. mattress electricity torture
