CCRA3 flooding projections, task 2a: high resolution climate change projections — fluvial. Technical note.
Wallingford, UK Centre for Ecology & Hydrology, 31pp.
(UKCEH ref. NEC07063 / Issue number 1.2)
(Unpublished)
As part of the CCRA3 flooding projections project, this task provides: 1. estimates of percentage changes in flood peaks for locations across the UK, using UKCP18 probabilistic projections applied for a set of global mean surface temperature (GMST) changes (ranging from 1.0°C to 4.5°C in increments of 0.5°C); and 2. estimates of change in return period corresponding to a range of peak flow uplifts, as look-up tables, for locations across the UK.
The data are provided for use within the Future Flood Explorer (FFE) to investigate potential future flood risks under climate change, under a range of adaptation options.
This technical report details the methodology used to produce the flood peak and return period data, including differences in the methods used for Great Britain and Nothern Ireland.
