Monitoring and early warning systems for rotational and translational slides

Geological and Hydrogeological risk

Monitoring rotational and translational slides

Description

By means of automatic monitoring systems, the most significant geotechnical and weather parameters for the stability of landslide fronts can be monitored remotely, continuously and in real time, by means of wireless stations and other devices located on the landslide. These systems allow analysing current movements and understanding the evolution of the most significant parameters, such as the sloping profiles of the landslide body, the water table levels and the structural deformation. One of the strengths of the CAE offer is the massive use of ultra low consumption wireless devices which can be configured in a Mesh type network. Data and pictures can always be viewed remotely, to assess any risks due to the evolution of the instability, allowing a timely activation of civil defense plans when necessary.

Case history

CALABRIA REGION

Following the landslide on the night of 1 st of February 2011, the Civil Protection of Calabria region has decided to install CAE landslide monitoring system to help managing the supervision of the area in real time. The landslide caused the evacuation of 5 houses and the blockage of the main road of access to the city. Civil Protection, Fire Fighters, Local Gas and Electricity Technicians, worked together to allow the re-opening of the road following the landslide. continue

CIVIL DEFENSE OF ABRUZZO

On February 12, 2017, an extensive landslide occurred in the hamlet of Ponzano (Civitella del Tronto). The instability resulted from the effects on the ground of combined actions caused by the earthquake activities of the previous months and by the extraordinary snowfalls occurred in the area during last winter. The implemented monitoring system mainly aims at evaluating in time the need to evacuate further areas or, on the contrary, the possibility to let the evacuated population safely come back to ... continue

CIVIL DEFENSE OF MOLISE

After the huge landslide occurred in the Municipality of Civitacampomarano, an automatic monitoring and early warning system in real time has been implemented and tested, aiming at guaranteeing public safety and managing the emergency situation. continue

CIVIL DEFENCE OF ABRUZZO

In February 2017, in the Municipality of Civitella del Tronto, and more precisely in the division of Borrano, has been reactivated by an extensive landslide phenomenon which affected large areas of the territory. Plausible causes of this phenomenon date back to a series of hydrogeological instabilities related to geotechnical and lithological characteristics of the outcropping formations, as well as to geological-structural evolution of this area and to an unorthodox rainwater regulation. This phenomenon has worsened after the last earthquake and ... continue
