remained in an unsatisfactory condition for a shorter time than did the 'rotated'
time series shown in red colour. However, its maximum extent of failure when
it failed was more than the rotated time series. These characteristics of
hydrologic time series can be captured by the measures/criteria namely
'reliability', 'resilience' and 'vulnerability' as suggested by Hashimoto et al.
(1982 a, b). These measures/criteria are described in subsequent sections.
