An Empirical Formula for Design Flood Estimation of Un-Gauged Catchments in Brahmani Basin, Odisha

Several statistical methods, viz. flood frequency analysis and hydro-meteorological methods (i.e., unit hydrograph approach) are available for estimation of design flood in un-gauged catchments. Till today, the empirical formulae are relevant as the latest methods require adequate field observation and collection of sufficient data. The available formulae such as Dicken’s formula, Ryves formula and Inglis formula are applicable, respectively, to...
