Abstract:The aim of this study is to identify the sources of uncertainty that induce the largest uncertainties in the model outcomes and quantify this uncertainty using expert elicitation. Analysis of expert opinions showed that the Qh-relation and the roughness predictor of the main channel cause the largest uncertainties for design water level computations. For effect studies, the floodplain topography, weir formulation and discretisation of floodplain topography induces the largest uncertainty.
