Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and input data are to some extent inherently erroneous. The check the influence of data errors on the model results, it is necessary to perform some additional analysis. This paper deals with the impact of input data uncertainly on model results, considering only compiled models (those that cannot be conceptually changed, or modified on the source code level). Three forms of data uncertainly representation are presented: intervals, fuzzy sets and statistical distribution.
