GI3.5 - Electromagnetic sensing techniques and geophysical methods for critical and transport infrastructures monitoring and diagnostics
Convener: Jean Dumoulin  | Co-Conveners: Francesco Soldovieri , Lorenzo Bigagli 
 / Thu, 11 Apr, 10:30–11:15  / Room R7

The critical and transport infrastructure are susceptible to the consequences of natural disasters and also sensitive to human-induced/man-made/anthropogenic disasters. In many cases, the large extent and complexity of the infrastructure, its physically dispersed and decentralized nature, the many public and private entities involved in its operations, the critical importance of cost considerations, and the inherent requirement of convenient accessibility to its services by all users - make the infrastructure particularly vulnerable to security and safety threats.
On the other hand, interdependencies exist between the sectors based on the critical infrastructures (energy, transport, communication,..) and nearly every other sector of the economy, and the effective operation of these systems is essential to the national and transnational economic productivity and society aspects.
In this framework, it is of timely interest a research activity aiming to the development and implementation of non-destructive electromagnetic monitoring systems based on ICT and sensor technologies. The overall aim is to provide emergency and disasters stakeholders with high situation awareness by means of real time and detailed information and images of the infrastructure status.
Therefore, the session will be concerned with several main aspects relative to the integrated and non invasive monitoring of the infrastructure as:
- State of art and novel instrumentation, sensing techniques, as well as data processing approaches to perform high resolution diagnostics and monitoring. In particular, some of the sensing technologies of interest will be (but not only) : optic fiber sensors, Synthetic Aperture Radar satellite platform based, hyperspectral spectroscopy, Infrared thermography, Ground Penetrating Radar, low-frequency geophysical techniques, Ground based systems for displacement monitoring, sonic and ultrasonic sensors, capacitive tomography.
- Sensor cross validation, synergy and data fusion and correlation schemes that are crucial for the set-up of a multi-method, multiresolution and multi-scale electromagnetic detection and monitoring of surface and subsurface changes of the infrastructure.
- Integration of electromagnetic technologies with new ICT information and telecommunications systems enables remotely controlled monitoring and surveillance and real time data imaging of the critical infrastructures.
- Numerical simulations of infrastructure behaviour under sudden events or other external solicitation and connexion with sensing techniques measurements.

Public information: Authors of GI 3.5 posters will have the opportunity to present a short summary and exchange on their works.

In particular, to promote this time of exchange and favour discussion, authors of the following 5 contributions are invited to present their works with an extended time of 6 min (i.e. question):

- EGU2013-7961(ys) by William Martin, Alexandre Nassiopoulos, Vincent Le Cam, Raphaël Kuate, and Frédéric Bourquin, "Web-based remote sensing of building energy performance"

PSD 1.7 of session GI 3.5 will allow participants to share their respective experiences on Electromagnetic sensing techniques and geophysical methods for critical and transport infrastructures monitoring and diagnostics.

To conclude an open discussion on GI3.5 topics will be proposed and possible evolution of session GI3.5 will be examined.
