Abstract EN
Design storms are very useful in many hydrological and hydraulic practices and are obtained from statistical analysis of precipitation records.
However considering design storms, which are often quite unlike the natural rainstorms, may result in designing oversized or undersized drainage facilities.
For these reasons, in this study, a two-parameter double exponential function is proposed to parameterize historical storm events.
The proposed function has been assessed against the storms selected from 5-year rainfall time series with a 1-minute resolution, measured by three meteorological stations located in Calabria, Italy.
In particular, a nonlinear least square optimization has been used to identify parameters.
In previous studies, several evaluation methods to measure the goodness of fit have been used with excellent performances.
One parameter is related to the centroid of the rain distribution; the second one is related to high values of the standard deviation of the kurtosis for the selected events.
Finally, considering the similarity between the proposed function and the Gumbel function, the two parameters have been computed with the method of moments; in this case, the correlation values were lower than those computed with nonlinear least squares optimization but sufficiently accurate for designing purposes.
