The primary need of water resource development in any area depends on estimation of rainfall at different probabilities for efficient planning and design of irrigation and drainage systems, command area development, soil and water conservation programmes and the optimum utilization of water resources in various agricultural production systems. The annual maximum daily rainfall data of 18 years (1991 to 2008) was obtained from ARS, Mulde. It was analyzed for maximum one day and extended days (up to 6 day) rainfall for Mulde. Normal, Log Normal, Gumbel, Pearson Type-III and Log Pearson Type-III were used for extreme rainfall events. The relationships between annual maximum values of 1 day and D-days rainfall were found polynomial for Mulde (R2 = to ). Based on statistical test for goodness of fit, the Pearson Type-III distribution was found as the best fit for observed 2-day, 5-day and 6-day annual maximum rainfall. Log Normal distribution gives the best for the annual maximum one day and 3-day annual maximum rainfall data whereas, normal distribution gives the best for the annual maximum 4-day annual maximum rainfall data for Mulde. Maximum value of 1-day rainfall for Mulde ranges from to mm. Maximum value of 2-day rainfall ranges from to mm. | Frequency analysis for one day to six consecutive days of annual maximum rainfall for Mulde, Dist: Sindhudurg
