Fiber optic sensors engineering for the monitoring of structural reinforcements on unstable slopes

project-INMOSTRA-AncoraggioStrumentato-evidenza Geo-Hydrological risks are one of the main sources of economic losses for our country causing a huge number of victims and damages. From 1966 to 2015, landslides and floods caused 1948 casualties, 3524 injured and more than 412,000 displaced people. The Venetian mountain has always been subject to major landslides and, almost every year, new emergencies occur with the intensification of the autumn and spring rains, which are increasing due to ...

Research and development of optical fiber sensors for geotechnical and environmental monitoring

evidenza-PDFOS-DistributedStrainPile-20170131 Application of optical fibers is generally aimed at large bandwidth transmission. Few people know that the proposal of optical fibers as sensing elements is almost as old as their proposal as transmission media, and over the last two decades fibre optic sensor (FOS) technology has assumed a dominant role in several fields of application. As a matter of fact, FOSs offer many advantages with respect to legacy electronic and mechanic sensors. ...

Dikes and Debris Flows Monitoring by Novel Optical Fiber Sensors

project-DOMINIO-fronte-evidenza With more than 5 million people affected, more than 1000 killed, and with estimated total damages exceeding 4.5 billion Euros just in Europe and during the last decade, floods are among the most disruptive natural events threatening our Society. Due to increase in extreme weather events and rapid socio-economic developments in vulnerable locations, the risks connected to floods in general are growing rapidly, and the awareness of these risks ...

RIVERbank Surveillance bAsed on Fiber optic sEnsors

riversafe_fig_intestazione-evidenza In the last decades Europe and Italy suffered many damaging floods, causing thousands of deaths, the displacement of millions of people and billions of euros in insured economic losses. Veneto Region has been also strongly stricken in 2010. The European Commission has identified the need for adaptation of risk management in several documents in order to reduce the likelihood and/or the impact of floods [1]. Starting from these remarks, the main ...

Innovative System for Monitoring and assessment of hIgh risk LANDslides

smiland_fig_intestazione-evidenza One of the main challenges in the field of engineering geology is the comprehension of the triggering mechanisms of landslides and the forecast of possible evolutionary scenarios in order to assess the correct mitigation measures. Landslides can be initiated by a variety of triggers: from earthquakes to meteorological events, including intense or prolonged rainfall, rapid snow melting, and variations of the surface temperature conditions. ...
