| Zusammenfassung |
| Several hydrological analyses need to be founded on a reliable estimate of
the design storm, which is the expected rainfall depth corresponding to a
given duration and probability of occurrence, usually expressed in terms of
return period. The annual series of precipitation maxima for storm duration
ranging from 15 min to 1 day, observed at a dense network of raingauges
sited in northern central Italy, are analyzed using an approach based on
L-moments. The analysis investigates the statistical properties of rainfall
extremes and detects significant relationships between these properties and
the mean annual precipitation (MAP). On the basis of these relationships, we
developed a regional model for estimating the rainfall depth for a given
storm duration and recurrence interval in any location of the study region.
The applicability of the regional model was assessed through Monte Carlo
simulations. The uncertainty of the model for ungauged sites was quantified
through an extensive cross-validation. |
