CAE PROVIDES CIVIL PROTECTION OF REGIONE CALABRIA WITH THE MONITORING SOLUTION FOR THE LANDSLIDE OCCURRED AT CIRÒ.

Civil Protection of Regione Calabria, in cooperation with the regional Multi-Risk Functional Centre, chose CAE to carry out the implementation of a landslide real-time monitoring solution. The landslide happened during February 2011 at Cirò, located within the Crotone Province.

The event involved populated areas of the town, making necessary to move people from their households. It also gave evidence that the evolution of the natural phenomena should be monitored and carefully analyzed: the landslide, following its next movements, may hit the only road linking a whole district to the town.

In June 2011 CAE completed the installation of the real-time landslide remote monitoring system. Data measured by a number of geotechnical sensors placed in relevant points are received at the regional Multi-Risk Functional Centre, located in Catanzaro Province.

The specific solution currently operating at Cirò includes the installation of geotechnical sensors, chosen and placed according to the preferences of the professional geologist who started working in the area as soon as the land moved. He is the one who knows in detail what should be monitored and how the measurements should be taken. Further than geotechnical sensors, there are 10 wireless communication nodes, designed and developed by the R&D department of CAE. Two nodes work as signal repeaters, while four of them are connected to biaxial clinometers, other 2 nodes are connected to piezometers and the rest of the nodes collects data from the clinometric chains.

Data are transmitted through the wireless network according to a typical mesh structure until they reach the master AWS, located out of the landslide area in a safe place. From the automatic station, data enter the regional network for multi-hazard monitoring so to be delivered to any competent technical authority and Civil Protection officers.

Among the strengths of this innovative solution developed by CAE, actually appreciated by technical experts, there is the opportunity to use traditional geotechnical sensors in a new and innovative manner. Their wireless and remote usage in real-time makes easier the implementation and doesn’t affect the reliability of the data measurement and collection system.
