Abstract
In most of the practical cases, Flood frequency analysis is carried out due to the safe design of hydraulic structures. This paper represents the result of Flood frequency analysis for Padma River at Hardinge Bridge station. The Flood frequencies of 2, 5, 10, 20, 50, 100, 200, 300, 400, 500 and 1000 year Floods was analyzed by probability methods develop by Gumbel, Powell, Ven Te chow as well as Stochastic methods. The analysis was carried out for the duration of 13 years ranges from 2000 to 2012. This research aims to compare four methods of Flood frequency analysis to find the optimum method in terms of safe design of hydraulic structures. From the comparison between four methods the Gumbel and stochastic method may be recommended for designing and locating hydraulic structures.
