Spatial and temporal occurrence of rainfall-induced shallow landslides of flow type: A case of Sarno-Quindici, Italy

A process-based model for the definition of hydrological alert systems in landslide risk mitigation

“…Capparelli and Versace (2011) and Rahimi et al (2011) at the local scale, and Goetz et al (2011) and Cascini et al (2011) at the basin scale provide examples on the effectiveness of combining empirical and deterministic approaches in rainfall-induced landslide forecasting. In some cases, physically-based modelling does not improve significantly the prediction, but helps to clarify some physical aspects which allow the use of empirical relationships in forecasting (Goetz et al, 2011).…”

“…The more comprehensive approach seems to be the combination of the results coming from the application of both empirical and physically-based models (Capparelli and Versace, 2011;Cascini et al, 2011), through multi-disciplinary studies and process-based models (Scheuner et al, 2011). In fact, empirical models allow one to identify the hydrological variable related to landslide triggering and the minimum rainfall threshold for the instability, and physically-based models allow one to verify that threshold, analysing the effects on slopes under given rainfall events.…”

A "simulation chain" to define a Multidisciplinary Decision Support System for landslide risk management in pyroclastic soils

“…These studies were based on the utilization of advanced numerical codes, both commercial and in-house. Moreover, they took into account some predisposing factors, which are sometimes undervalued, such as stratigraphic details (Picarelli et al, 2004 (Guadagno et al, 2003), springs and morphological cuts (Cascini et al, 2010(Cascini et al, , 2011. Only recently, Damiano and Olivares (2010) added information intended to aid the authorities involved in land management in the southern Apennines to detect cases in which rainfall-induced slope failure may turn into flowslides.…”

Physically based modelling of soil erosion induced by rainfall in small mountain basins

“…Hyperconcentrated flows (Coussot and Meunier, 1996) transport a smaller amount of solids, but the volumetric concentration of sediments still exceeds 20%. The run-out distances and consequences associated with debris flows and hyperconcentrated flows differ greatly (Cascini et al, 2011a). Thus, discriminating between these distinct flow types is fundamental to an accurate assessment of source and propagation areas and to forecasting the potential damage to urban areas located near the outlet of a mountain basin.…”
