| Zusammenfassung |
| The volume and duration of
groundwater discharge following extreme winter recharge events in permeable
catchments can often be more disruptive than the peak discharge. An estimation
procedure for annual maxima flood series in permeable catchments is extended to
annual flood volumes for different durations. Growth factors for durations of 1
to 30 days and return periods of up to 250 years are derived for a sample of 12
permeable catchments in the UK. In most cases, adjusting the growth curves for
‘non-flood’ years has only a small effect and L-moment parameters show
little change with duration. L-CV and L-skewness are highly correlated for the
sample of Chalk catchments.
