Abstract

In order to evaluate different design assumptions, able to mitigate hydrological risk and protect the town of Chiavari (located in the north eastern part of Liguria region, Italy) from flood events of Rupinaro river, a detailed analysis of the temporal development of floods needs to be carried out. This work compares the volume in the stilling catchment to the total volume of flood starting from accurate hydrographs of flood events and rate of assigned return period. As a matter of fact, the general tendency of engineers and public administration is to adopt excessively conservative conditions which, decisively far from being real, end up discouraging and impeding projects. This work aims to provide reliable flood hydrographs associated to given return periods for the ungauged catchment of Rupinaro river, those hydrographs are necessary to design millwork dams.
