In un contesto in cui i cambiamenti climatici stanno modificando significativamente il regime delle precipitazioni, diventa sempre più importante poter prevedere gli impatti che tali variazioni possono avere sul territorio. I modelli climatici rappresentano uno strumento fondamentale per analizzare in dettaglio le risposte del sistema climatico a forzanti esterne, sia di origine naturale che antropica. Con questa tesi si vuole valutare l’effetto degli eventi intensi di pioggia e le loro variazioni future sulla erosività, in Sicilia Occidentale. Si utilizzano dati di pioggia osservati e proiezioni future da modello climatico ad alta risoluzione, e si valuta la loro potenziale capacità erosiva attraverso la variazione del fattore R della formula USLE.

Abstract
In a context in which climate change is significantly modifying the rainfall regime, it is becoming increasingly important to be able to predict the impacts that these variations may have on the land. Climate models represent a fundamental tool for analysing in detail the responses of the climate system to external forcings, both natural and anthropogenic. This thesis aims to evaluate the effect of intense rainfall events and their future variations on erosivity in western Sicily. Observed rainfall data and future projections from a high-resolution climate model are used, and their potential erosive capacity is assessed through the variation of the R factor of the USLE formula.| File | Dimensione | Formato | |
