- Abstract
At-site peak flow analysis is an important assessment used for estimation of peak flow magnitude in various return periods at a given location. In this paper, peak flow frequency analysis is carried out at Orkhon hydro-station in the Orkhon River of Mongolia based on observed daily flow data between 1945-2014. The analysis evaluates four most commonly used probability distributions namely Lognormal, Gamma, Log Pearson Type III and Gumbel Max for best reflecting historical flow data and estimation of maximum discharges. Kolmogorov-Smirnov and Anderson-Darling goodness of fit tests at 5% significance level were used for selecting best-fitting distribution at this site. Results indicate that Gamma was the best-fitted distribution based on goodness of fit test ranking. Using the Gamma distribution, peak flow magnitudes in 2- to 100-year return periods were estimated and historical peak flow magnitudes was evaluated for the return periods.
