Excerpt from Rainfall Frequency Analysis for 1-to 15-Day Durations in the Blacklands of Texas: July 1965 Frequency analyses of rainfall amounts for durations up to 15 days for the Blacklands of Texas are presented in this report. Similar analyses in the past were generally limited to durations of 24 hours or less Q).2 The results of these analyses cannot, with safety, be extrapolated beyond the 24-hour duration. Now a need has developed for information on much longer durations for guidance on the design and operation of flood control reservoirs. Low release rates required to gain desired flood control may take days to discharge stored flood waters. During this time storm inflow may recur because weather conditions frequently result in a sequential occurrence of runoff-producing storms over a period greater than 1 day. One analysis of interest is that of Kotz and Neumann (q), who utilized parameters of the gamma distribution to expand rainfall amounts from unit time to other durations, including the 15-day period. Their method required manipulation of long-term records and did not provide probable rainfall estimates for various recurrence intervals. Furthermore, new computations were necessary for each duration. In the study reported here, u.s. Weather Bureau data were analyzed for stations in and adjacent to the Blacklands of Texas. Frequency analyses were applied to annual maximum rainfall amounts occurring in l 2 4 7 and 15-day periods. Data from the Agricultural Research Service gages at the Blacklands Experimental Watershed near Riesel, Tex., aided in the interpretation of analyses.
