Flood Estimation of Sarda River Using Wakeby Distribution in Champawat District, Uttrakhand

Abstract

The Wakeby probability distribution function was applied to estimate extreme flood discharges associated to different return periods with 86 years length of the data in Champawat district of Uttrakhand. This distribution had advantages over other probability distributions because its parameters were found using the probability weighted moments that represent in linear trend the characteristics of present data. Wakeby distribution was a five parameters distribution used more than the other distributions reason for which was that it can attain wider range of distributional shapes as other ones. This study indicated that wakeby five parameter distributions used for analyzing the maximum annual discharge for the present study area. In this study we described the procedure to estimate the Wakeby distribution parameters for analysis of Sarda river discharge.
