Analytical derivation of the flood frequency curve through partial duration series analysis and a probabilistic representation of the runoff coefficient

The procedure is applied to several basins of the Romagna-Marche region (Italy), for which the results of a regional analysis conducted using the index method were already available, both in relation to annual maximum rainfall depths and peak discharges. A comparison of the results obtained by the two different procedures provides a basis for advancing some considerations regarding the potential of the proposed procedure and highlights aspects, which warrant further investigation.
