WebAM method is the peaks-over-threshold (POT) approach (also called the partial duration series approach). The POT sample is defined by all peak values that lie above a certain truncation level (usually called the threshold or base level) (Lang et al. 1999). Major difficulties in using the POT method are assuring the independence of the data
