The uncertainty of the reconstructed peak flow of a major flood was calculated. This was done with a set of local sensitivity analyses on six input variable. The peak flow total error was estimated at ±31%. Water height was the most influential variable on peak flow. Manning’s n was the greatest contributor to peak flow total error.
