This work presents the results of the continuous monitoring of two slopes of the OltrePò Pavese (northern Apennines, north-western Italy), representative of different contexts usually affected by shallow landslides. The first monitored site is representative of high gradient slopes with silty soils. The second one represents slopes with low-medium slope gradient and clayey soils. Hydrological monitoring allowed to identify the responses of the soils to different rainy and dry periods, focusing in particular on conditions which could predispose landslide triggering. As demonstrated by monitoring and by slope stability analyses though a simplified physically-based model, increase in pore water pressure during most intense rainfalls in wet periods, sometimes with development of perched water tables, can promote slope instability.

Abstract

This work presents the results of the continuous monitoring of two slopes of the OltrePò Pavese (northern Apennines, north-western Italy), representative of different contexts usually affected by shallow landslides. The first monitored site is representative of high gradient slopes with silty soils. The second one represents slopes with low-medium slope gradient and clayey soils. Hydrological monitoring allowed to identify the responses of the soils to different rainy and dry periods, focusing in particular on conditions which could predispose landslide triggering. As demonstrated by monitoring and by slope stability analyses though a simplified physically-based model, increase in pore water pressure during most intense rainfalls in wet periods, sometimes with development of perched water tables, can promote slope instability.
