Regionalization of unit hydrograph parameters. II: Uncertainty analysis (Q1360349)

We present a systematic analysis of uncertainty associated with two parameters, \(N\) and \(K\), in Nash's IUH model for different regional regression equations. The uncertainty features associated with \(N\) and \(K\) are further incorporated to assess the uncertainty of the resulting IUH. Numerical results indicate that uncertainties of \(N\) and \(K\) from the regional regression equations are too significant to be ignored.
