For early warning of disasters induced by precipitation (such as floods and landslides), different kinds of rainfall thresholds are adopted, which vary from each other, on the basis on adopted hypotheses. This work briefly discusses different schemes of rainfall thresholds, focusing attention on landslide prediction, with some applications to a real case study in Calabria region (southern Italy).

The extreme temperature events, the heat and cold waves, besides to have a significant impact on human health and activities, have negative influences also on mountain ecosystems. This work provides a characterization of heat and cold waves variability and trends in high-elevation sites of Central Mediterranean area, by using the long-term temperature time series collected in Montevergine. Main results highlight a positive trend in heat waves frequency and severity in the last 40 years. Hide

Probabilistic flood inundation mapping at ungauged streams due to roughness coefficient uncertainty in hydraulic modelling. The results of this study show that the proposed procedure supports probabilistic flood hazard mapping at ungauged rivers and provides water resources managers with valuable information for planning and implementing flood risk mitigation strategies.
