Abstract

Landslides in partially saturated pyroclastic slopes are strongly linked to rainwater infiltration, which is the main factor responsible for pore pressure and shear strength variations in shallow subsoil. Monitoring of the groundwater regime allows the most critical period for slope stability to be identified and the rela-tionship between critical pore pressure and rainfall to be explored. This paper de-scribes the monitoring of an unsaturated pyroclastic slope instrumented at Monteforte Irpino in southern Italy (Pirone et al., 2010), where suction and volu-metric water content measured at different depths were collected from 2006 to 2011. Using this database, typical aspects of the groundwater regime are de-scribed. The maximum water content is observed to be significantly lower than the saturated value measured in the laboratory (Nicotera et al., 2010). This condition affects permeability attained in situ during the wet period of the year and hence in-filtration.
