  • Hydrology and Hydrography
DEF

The frequency with which the maximum flood may be expected to occur at a site in any average interval of years.

OBS

Frequency analysis defines the "N-year flood" as being the flood which will, over a long period of time, be equalled or exceeded on the average once every N years. Thus the 10-yr flood would be expected to occur approximately 100 times in a period of 1,000 yr, and of these, 10 would be expected to reach the 100-year magnitude. Sometimes expressed in terms of percentage of probability; for example, a probability of 1 percent would be a 100-yr flood; a probability of 10 percent would be a 10-yr flood.
