Hydrological analysis of a rainfall event in Calabria

Between 12 and 13 November 2004 a considerable rainfall event occurred in the Calabria Region (southern Italy). This event started in the south part of Calabria and, during its evolution, it interested all the Region with remarkable damages. The analysis of the cumulate precipitation recorded during the event, from 6:00 a.m. on November 12th to 6:00 a.m. on November 13th and the evaluation of the return period for the maximum rainfall of 1 hour, 3 hours, 6 hours, 12 hours and 24 hours stored in some rain gauges were performed. The hydrologic model WRROOM (Watershed Rainfall Runoff Object Oriented Model) was applied to study rainfall-runoff transformation in 4 of the principal basins of the Calabria Region: the Neto River at the closing section of Rocca di Neto and the Tacina River at the closing section of Serrarossa for the Ionian side, the Mesima River at the closing section of Sbarretta and the Petrace River at the closing section of Gonia for the Tyrrenian side. Results of the hydrological analysis of the rainfall event occurred in Calabria in November 2004 are presented.
