On the feasibility of thresholds for the classification of daily precipitation in Lazio region
Daily rainfall series analysis is crucial both for engineering design purposes, freshwater management and it currently used in various types of agriculture management models to evaluate the associated drought risk. More recently the studies of daily rainfall events are used to investigate changes in rainfall occurrence. A basic approach to accomplish this aim is to identify the magnitude of the events and regroup them into categories. Some studies in literature proposed a classification of daily rainfall events based on single thresholds, which are commonly defined for quite large areas.
