Abstract :
Estimation of Peak Flood (PF) for a given return period is considered as one of the most important parameters for planning and design of hydraulic structures, river protection works, development of integrated water resources management projects, etc. This can be achieved by adopting various approaches viz., flood frequency analysis, rational method, empirical equation, envelope curve and Synthetic Unit Hydrograph (SUH) approach. In this paper, SUH approach is adopted for estimation of PF for the ungauged catchments wherein rainfall depth (i.e., 24-hour maximum rainfall) becomes an important parameter. This can be determined through Extreme Value Analysis (EVA) by fitting Gumbel probability distribution to the Annual Maximum Rainfall (AMR) series that is derived from the daily rainfall data. Parameters of the distribution are determined by maximum likelihood method and used for estimation of rainfall. Goodness-of-Fit tests viz., Anderson-Darling and Kolmogorov-Smirnov are applied for checking the adequacy of fitting Gumbel distribution to the AMR series. The rainfall depth is computed by multiplying the estimated 1-day maximum rainfall with 1.15 and used as an input for estimation of PF. The paper presents the procedures adopted in estimation of PF for the ungauged catchments of Suketi Khad using SUH approach and the results obtained thereof.
