In using small-scale topographic maps, we always have to bear in mind their inaccuracy, and that the parameters estimated on their basis may be burdened with significant differences. The following work allows for an analysis of error size occurring when estimating runoff hydrographs for uncontrolled catchments that are dependent on catchment hydrograph parameters, estimated based on topographic maps in 1:50 000 scale.
