HarmoniRIB - 6. Uncertainty assessment in flood flows and wave volumes in the Svratha basin, Czech Republic

For this case study only the uncertainty involved in input proposed flood wave Q100 was taken into account. The data series of the hydrogram was characterised as a probability type depending on individual sequential data. The actual degree of uncertainty for the hydrogram was characterised by the data precision class. The uncertainty for the hydrogram was also the subject of consultations with hydrologist. The uncertainty for the hydrogram was set at 15% with a normal (Gaussian) distribution. The time correlation was selected as 100 hours. 100 new waves were generated by the DUE program from the original input flood wave on the basis of this input uncertainty.
