Abstract

Statistical technique developed by Hershfield has been used in this note to determine one-day PMP estimates for the plain areas of Uttar Pradesh. Extreme annual one-day rainfall data was collected for 230 stations in this region from the scrutiny of daily rainfall data of 60 to 70 years from 1891 to 1960. The enveloping value for the frequency factor Km in the modified Chow's general formula was found to be 12 for this region. This value was utilized in obtaining PMP values for 230 stations in this region. On the basis of this data a generalized chart of PMP was prepared for the plain areas of Uttar Pradesh for one-day duration. It has been seen that on an average in this region one-day PMP values obtained by this technique are 2.4 times the highest observed one-day rainfall during the past 60 to 70 years.
