The following figures describe the process and result when you sort a time series file containing a wave climate where each event is defined by an individual duration.
Consider a case where a harbour experience severe seiching for waves with wave periods above 10 s that comes from SE (120 degrees -150 degrees). By sorting the available data using only 2 items and relevant class intervals it is possible to easy determine how often the seiching will occur.
The results in Figure 23.15 shows that during a total period of 35064 hours, expressed by 11333 time steps in the input time series, seiching will occur only during 7 hours, i.e. for 0.02% of a year.
