SUMMARY
The discussion clarifies that if there are five floods recorded over a span of 100 years, the flood frequency is calculated as 5 per 100 years. Consequently, the flood return interval is determined to be every 20 years, derived from the formula 5/100 = 1/20 years per flood. This indicates that, on average, one flood is expected every 20 years, although this is an average and does not guarantee consistent occurrences.
