The peak over threshold method and its uncertainty in determining of T-year maximum discharges: Case study at the Topľa River

Year, pages: 2019, 32 - 43

The paper deals with the comparison of the two most commonly used methods in estimating of the T-year maximum discharges. As input data a set of daily discharges and peak discharges on the Topľa River for the period of 1931–2015 was used. The method of maximum annual discharges (AM) with the most used theoretical probability distributions (Log-Pearson III, Gamma and Log-normal), was used for estimating of T-year maximum discharges. As an alternative to this method, the Peak Over Threshold Method (POT) was used. We analysed the effect of the threshold level selection and using of maximum daily discharges on the accuracy of T-year maximum discharges estimation. We also analysed suitability of selected types of theoretical probability distributions for the accuracy of the T-year maximum discharges estimated using the POT method.
