On January 11-13, 1997, an unusual rainstorm hit the Xerias torrent watershed and the wider area of Corinth, Greece. The storm caused a devastating flood in the town of Corinth with severe damage and human losses. The damage was attributed to heavy rainfall and runoff and also to human interference in the channel of the torrent and in the floodplain. Quantification of the hydrologic response of the watershed and determination of suitable measures for mitigating flood impacts from similar events in the future was a difficult task due to lack of hydrometeorological data. This problem is faced here by investigating the hydrologic response of the watershed using the SCS method. The analysis has shown that the rainfall in the watershed ranged from 123-358 mm (weighted average 201 mm); its return period was of the order of 1000 years for the central part of the watershed and for 24-hour duration, but much lower for shorter durations. The peak discharge in the outlet of the watershed exceeded 600 m3/s (return period of the order of 100 years) and the flood volume was more than 55% of rainfall. Considering the physical and hydrological characteristics of the watershed and the conclusions drawn, measures are proposed and discussed for mitigating the flood impacts from similar events in the future.
