Identification of Proper Distribution for Flood Frequency Analysis of Sarda River using L-Moments

Kiran Rani, Dr. Mrs Jyothi Prasad

Abstract: Flood frequency analysis of River Sarda (Banbasa Barrage) site in Champawat district in Uttrakhand was carried out using annual flood peak series for 86 years (1930-2015). The objective of the study was to determine the proper probability distribution using Generalized Extreme Value distribution (GEV), generalized logistic distribution (GLO) and generalized Pareto distribution (GPA), Pearson type 3rd distribution (PE3) and wakeby five parameter distribution whose parameters were estimated using the method of L-moments. The proper fit distribution is selected on the basis Zdist- statistic test. The present study shows that wakeby five parameter distribution identified as the proper distribution for analyzing the flood frequency analysis of Sarda river using L -moment
