Recent advancements of landslide hydrology

Occurrence of rainfall-induced landslides is increasing worldwide, owing to land use and climate changes. Although the connection between hydrology and rainfall-induced landslides might seem obvious, hydrological processes have been only marginally considered in landslide research for decades. In 2016, an advanced review paper published in...

Water retention and shrinkage curves of weathered pyroclastic soil

The modelling of the triggering mechanism of rainfall-induced landslides in slopes covered by pyroclastic soil (as the area surrounding Mount Vesuvius in Campania, Italy) requires the hydraulic characterization of soil in unsaturated conditions in order to analyse the slope response to rainfalls. In previous studies carried out on Campanian...

A New Tool for Large-Area Analysis of Transient Pore Water Pressures in Layered Shallow Covers Prone to Failure

In this paper we present a modified version of an existing, physically-based model for shallow landslide susceptibility analysis over large area. In general, the potentially unstable soil cover is considered uniform and homogeneous, over impervious underlying bedrock. In several case studies, this was proven to be unrealistic. The possibility of...

Physical modelling of rainfall induced landslides under controlled climatic conditions

A series of small scale physical modelling tests are performed in a geotechnical drum centrifuge in order to investigate the triggering mechanisms of landslides due to rainfall. They are conducted under controlled conditions of rainfall intensity and duration, ambient relative humidity, wind, and temperature. These tests have been designed to...
