Abstract
A quick and simple procedure has been developed for evaluating maximum point rainfall for different return periods for any location in the plains of north India. According to this procedure, 2-year one-day rainfall of a location is estimated from the 2-year generalized chart of the region. Average district rainfall ratios for higher return periods of 5, 10, 25 and 50 years to 2-year return period are obtained with the help of (i) district average ratio map of 100/2 and (ii) frequency interpolation nomogram. The magnitudes of 5, 10, 25, 50 and 100-year rainfall are then obtained by multiplying the 2-year value by the corresponding district average ratios pertaining to different return periods. The estimates of point rainfall obtained by this procedure are quite comparable with those obtained directly by the Gumbel method. By using the procedure given in this study, a design engineer or a hydrologist can estimate point rainfall of different return periods for any station in north Indian plains without undertaking elaborate statistical calculations.
