Description:Precipitation-frequency values for periods up to 10 days have been available for a number of years. This report suggests a time distribution for precipitation-frequency values for the 4- through 10-day durations over the Arkansas-Canadian River Basins. The suggested distributions were developed from single station data and are considered valid for basins up to 100 square miles and possibly a little larger. The basic data period is 1941-70, and a sample of 1,712 storm periods for each duration was examined. Intrastorm comparisons of observation-day data and precipitation "bursts" led to the conclusion that 4- to 10-day storms over the Arkansas-Canadian River Basins are basically two-burst storms. The bursts tend to come at the beginning and ending of the storm period, and the larger burst is equal to the 1-day precipitation-frequency value for the same return period used for the total storm.
