Abstract

Due to the errors in processing rainfall and runoff data, model inadequacy, and other factors the unit hydrograph (UH) derived by any method involves uncertainty. With the presence of uncertainty in UH, the design flood event also subject to uncertainty. In this paper, the methodologic framework of uncertainty analysis of UH is presented along with a numerical example. In addition, the implications of such uncertainty in the design and performance evaluation of a hydraulic structure are discussed. -from Authors
