Hydraulic characterization of an unsaturated vegetated soil: The role of plant roots and hydraulic hysteresis

Ana Sofia Dias et al.

Summary: Flowslides and debris flows in granular soils are dangerous and can be triggered by rainfall. Accurate groundwater analysis is important for early warning systems to mitigate landslide risk. This paper presents a laboratory investigation on the hydraulic behavior of pyroclastic unsaturated deposits, highlighting the significance of hydraulic hysteresis and the presence of roots in shallow soils.

Analytical and numerical modelling of air trapping during wetting of unsaturated soils

Riccardo Scarfone et al.

Summary: At high saturation levels, the measured soil water retention curve in wetting tests can differ from the true curve due to air trapping. The true curve only reaches full saturation at a positive suction value. The most accurate way to represent air trapping is to use the true curve combined with a gas conductivity expression.

Hydraulic hysteresis of natural pyroclastic soils in partially saturated conditions: experimental investigation and modelling

Ana Sofia Dias et al.

Summary: This study proposed a method to obtain soil hydraulic characterization in unsaturated conditions on natural pyroclastic samples and verified its feasibility through experiments. The approach enables a full evaluation of soil hydraulic properties and the effects of hydraulic hysteresis, successfully describing the hysteretic behavior of pyroclastic soil under various conditions and paths.

Hydro-mechanical analysis of a surficial landslide triggered by artificial rainfall: the Ruedlingen field experiment

Panagiotis Sitarenios et al.

Summary: This paper interprets the hydromechanical behaviour of a steep, forested slope during an artificial rainfall event and identifies water exfiltration from bedrock fissures as the main triggering agent for slope failure.

Prediction of shallow landslides in pyroclastic-covered slopes by coupled modeling of unsaturated and saturated groundwater flow

Pasquale Marino et al.

Summary: The study focuses on the triggering mechanism of shallow landslides on slopes covered with unsaturated shallow pyroclastic deposits in the mountains around Naples. It suggests that the temporary storage of water in a perched aquifer in the fractured bedrock may affect slope drainage, leading to landslide predisposing conditions. Physically based modeling indicates that different responses of soil and aquifer to precipitation, influenced by antecedent conditions, can play a key role in landslide triggering.

Integrating local pore water pressure monitoring in territorial early warning systems for weather-induced landslides

Gaetano Pecoraro et al.

Summary: The study proposed a methodology that integrates meteorological monitoring and pore water pressure measurements, which was tested in 30 hydrological basins in Norway. By analyzing data on weather-induced landslides, meteorological monitoring, and pore water pressure measurements, an effective territorial warning model was developed, providing accurate identification and warning of landslide events.
