Abstract: Sensitivity analysis is well recognised as being an important aspect of the responsible use of hydraulic models. This paper reviews a range of methods for sensitivity analysis and presents two illustrative examples of differing complexity, which illustrate the deficiencies of standardized regression coefficients, derivatives and other local methods of sensitivity analysis. The use of global variance-based sensitivity analysis is shown to be more general in its applicability and in its capacity to reflect non-linear processes and the effects of interactions among variables.
