Abstract: The aim of this work is the performance evaluation, under rare rainfall events, of the stormwater drainage system of the city of Argos, Argolis region, Peloponnese, Greece. For this purpose, the system is modelled using the software package SWMM. Synthetic storm hyetographs for return periods from 5 to 100 years are constructed based on the generalized Intensity-Duration-Frequency (IDF) curve that is available for the city, as well as limited information and assumptions regarding the system itself. System performance is evaluated using four indices based on statistics of both peak flow velocity in underground conduits and flood duration at system manholes. These indices revealed serious deficiencies of the system, which appear even for low return periods (e. g. 5 years).
