3 Index flood method
3.1 General principle
The method has already been described in detail in Crochet (2012a,b) and Crochet & Þórarins-
dóttir (2014) and so is only summarised here. The index flood method (IFM), proposed by
Dalrymple (1960) can be used to estimate the T -year flood quantile at ungauged locations or
at gauged sites with short records

of the analogue method is introduced. In Section 3 hydrological and me-
teorological data used in the analysis are presented. Section 4 describes the different strategies
considered for implementing the method and Section 5 presents some results. Some concluding
remarks are made in Section 6.
