Quantification of uncertainties in a 2D hydraulic model for the Dutch river Rhine using expert opinions

Hydraulic–morphological river models are applied to design and evaluate measures for purposes such as safety against flooding. These numerical models are all based on a deterministic approach. However, the modeling of river processes involves numerous uncertainties. 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 opinions. Experts have been selected based on a Pedigree matrix. The selected experts are asked to list and quantify the most important uncertainty sources for two si... Mehr ...
