Comparison of automatic procedures for selecting flood peaks over threshold based on goodness‐of‐fit tests

Abstract: In comparison with the traditional analysis of annual maximums, the peaks over threshold method provides many advantages when performing flood frequency analysis and trend analysis. However, the choice of the threshold remains an important question without definite answers and common visual diagnostic tools are difficult to reproduce on a large scale. This study investigates the behaviour of some automatic methods for threshold selection based on the generalized Pareto model for flood peak exceedances of the t… Show more

“…Therefore, although the use of macroregions is found to be relevant in the flood context (Durocher et al, ; Mostofi Zadeh & Burn, ), results of the present study do not support their use in rainfall pooling group formation across Canada. This may be attributed to the difficulty in defining appropriate macroregions for rainfall durations, as well as to the marked spatial character of rainfall.…”

“…An indicator for determining if a threshold was correctly selected is to use a goodness-of-fit test to verify that GPA is a proper 120 distribution (Davison and Smith, 1990). The p-value of such tests were used recently to develop automatic selection procedures based on the identification of the maximum p-value and the first threshold respecting a given significance level (Durocher et al, 2018b;Solari et al, 2017).…”

“…The significance-based and the maximum p-value thresholds are then searched among the candidates and the final threshold is taken as the one with the highest number of peaks. Following Durocher et al (2018b), the significance-based threshold is chosen as the first threshold that has a p-value greater than 0.25 and a relative discrepancy with the 1 PPY threshold lower than 25%. To speed up the computation, a table is used to interpolate the p-240 values of the Anderson-Darling test (Choulakian and Stephens, 2001).…”
