Description/Abstract
This paper provides a comparison of gauge interpolated and radar derived precipitation data sources for an upland
catchment in the UK for a time period when extreme hydrological conditions were prevalent. Subsequently,
a performance measure was used to evaluate the accuracy of hydrological simulation of extreme conditions using
the two independent precipitation data sources within a HEC-HMS modelling framework. Discrepancies between
gauge and radar time-series precipitation records were found to coincide with elevation, spatial distribution
of precipitation and distance from the radar source. The Nash-Sutcliffe performance measure indicated that
despite the higher temporal and spatial resolution of the radar data, interpolated gauging station records produced
comparative accuracy when replicating the extreme hydrological event of Summer 2007
