摘要: Abstract. In this paper, we present a methodological approach based on comparative analysis of floods that occurred in wide region over long period and the climatic data characterising same period, focusing climate trend. The method simplifies several time series by defining some indexes (e.g. monthly, bi-monthly, ... m-monthly precipitation, temperature, wet days precipitation intensity monthly flood number) can be used to study phenomena such as are characterised spatial temporal variability. was investigate potential effect variation damaging tested for Calabria (Italy) using historical from 1880 2007. results showed number correlated with days, daily intensity. following trends were recognised: decreasing almost constant intensity, increasing linearly floods. A second-order polynomial trend slight decrease since seventies, which might explained favourable conditions during and/or awareness vulnerability.
