Abstract

Monthly, seasonal and annual areal rainfall of the upper Narmada catchment upto Narmada Sagar damsite is analysed using the daily data of 38 stations from 1901 to 1980. The statistical parameters are presented. Trend analysis showed some significant changes in rainfall of the upper Narmada catchment during the past 80 years. The monsoon and annual rainfall showed an increasing trend from the beginning of the present century upto 1945. Thereafter, it stabilised around the long-term mean. The increased southwest monsoon and annual rainfall from 1921 to 1950 over the catchment was mainly due to an increase in the July rainfall of this period. During the last three decades (1951-1980) there was no significant departure in rainfall over the upper Narmada catchment from the long-term mean.
