Flood frequency analysis is the most important statistical technique in understanding the nature and magnitude of high discharge in a river. The objective of frequency analysis is to relate the magnitude of events to their frequency of occurrence through probability distribution. The scale and shape parameters of the distribution were estimated using method of moments. The study which was carried in Vijayawada aimed at Prediction of Flood frequency analysis of Krishna river of Prakasam barrage at Vijayawada using Gumbel's, California, Hazen's methods. These are estimated using different flood data from 1990-2014 of Prakasam Barrage which were collected from Water Resources Department of Vijayawada. The magnitude of the flood out comes to be for 20 years and 50 years is1823.33TMC and 1873.34 TMC.
