Our primary objective in the present paper is to search for an appropriate probability distribution for modeling of the distribution of daily rainfall amount in the Mahanadi Delta of Odisha. To achieve this objective, 17 types of probability distributions were fitted to the data on daily rainfall volume for a period of 28 years during rainy season. Kolmogorov-Sminov, Anderson-Darling and Chi-Squared goodness-of-fit tests were employed in order to test the strength of the fitted distributions and to identify the most appropriate one.
