In thread311-297005, I asked about the standard use of a 3-hour return period to determine the maximum load occurring in a 100-year storm (e.g. Hs=15m). The underlying assumption is that when a 100-year storm occurs, you want your structure to survive the worst load expected to occur if the storm lasts 3 hours. Some replies indicated that the statistics should be pretty reliable over 3 hours, i.e. there will be enough peak load events that their distribution can be fit to an expected distribution for extreme values.
Can someone give me a citation for this? I want to point to a reliable source that indicates that a 3-hour return period is appropriate for estimating the design load in 100-year storm conditions.
