HSuper mario bros 4 apk downloadA 100-year flood does not only happen once every 100 years. So why is it called that? This term can be misleading. The phrase, “100-year flood” is an example of a return period for a flood event. Return periods are a common, yet widely misunderstood, metric for the occurrence of natural hazards such as floods, earthquakes, and eruptions. Malamud et al. (1996) showed that a flood of equivalent size to that experienced on the Mississippi in 1993 has a recurrence interval on the order of 100 years when a power-law distribution is fitted, but a much longer recurrence interval — on the order of 1000 years — using the USA's standard LP3 method.
