objectives Quantification of peak flood (extreme-hydrological event) discharge of a channel or river saying for a desired return period is a pre-requisite for design, planning and management of hydraulic configurations like, dam, bridges, spillways, barrages etc. this paper figure out the result of a study carried out at estimation the frequency of Lower Godavari River division’s flood by using the methods of Gumbel distribution which is one of the probability distribution methods used to model stream flows. The method was used to model the annual maximum river discharge for a period of 25 years (1991-92 to 2015-16). From the analysis of regression equation (R2 ) gives a values, which is shows that this distributional method (Gumbel) is suitable for prophesy the expected flow in future on this river.
