Ten-year storm definition
Ten-year storm means a storm that is capable of producing rainfall expected to be equaled or exceeded on the average of once in 10 years. It may also be expressed as an exceedance probability with a 10% chance of being equaled or exceeded in any given year.
Ten-year storm means the storm magnitude expected to be equaled or exceeded on the average of once in 10 years. It may also be expressed as a probability that there is a 10% chance that the storm magnitude may be equaled or exceeded in any given year. A 10-year 24-hour storm occurs when the total 10-year storm rainfall amount occurs in a 24-hour period.

Ten-year storm means the surface runoff resulting from a rainfall of an intensity that, based on historical data, is expected predicted to be equaled or exceeded, on the average, once in 10 years, and of a duration that which will produce the maximum peak rate of runoff for from the watershed of interest under average antecedent wetness conditions.
Ten-year storm or “Ten-Year Storm Event” means a storm that is capable of producing rainfall expected to be equaled or exceeded on the average of once in 10 years.
