This paper illustrates the performance of the FORGEX method of rainfall
growth estimation. Results are presented for three regions of the United
Kingdom: the East Midlands, north-west England and south-west England. Focused
rainfall growth curves are compared between regions and between different sites
within each region. Typical growth curve shapes are discussed with reference to
the climate of each region. Daily growth curves are derived from a large number
of records of annual maximum rainfalls. A smaller number of hourly annual
maximum series is available for estimation sub-daily rainfall growth curves.
Rainfall growth rates are compared with the results of a widely used method. The
present method allows more local and regional variation in growth rates. The new
growth rates are higher for durations of 1 and 2 days in parts of south-west
England, but lower for moderate return periods at some focal points in the
north-west. In the East Midlands, the new 1-hour growth rates are considerably
higher for long return periods.
Confidence limits for growth rates are derived by bootstrapping. This is
accomplished by fitting a large number of growth curves to resampled sets of
rainfall data. |
