Electrical resistivity is sensitive to various properties of concrete, such as water content. Usually used on the surface of old structures, devices for measuring such properties could also be adapted in order to be embedded inside the constitutive concrete of the linings of new tunnels or in new bridges, to contribute to structural health monitori...

Controlling the risk of scouring of structures, beds or banks due to natural hazards (floods, floods, extreme hydraulic regimes, dam failures) is a major challenge for sustainable development and land use planning. These processes are the main cause of destruction of buildings (civil engineering structures, earthworks, buildings) during major flood...
Following a controversy over the construction of a waste incinerator in the Fos-sur-Mer industrial area (France), residents pointed to the lack of knowledge of the industry's cumulative impact on their health and environment. Under pressure, some of their elected representatives supported the creation of an independent scientific organization, the ...
Recycling of asphalt has become a well-established practice in many countries, however the road pavement industry remains a bulk consumer of extracted raw materials. Novel solutions that find root in circular economy concepts and life?cycle approaches are needed in order to enable optimisation of infrastructure resource efficiency, starting from th...
The pooling of results from three French projects (Matriochkas, MicroMégas and Roulépur), within the framework of a working group on methodological harmonisation, makes it possible to analyse the performance of a wide range of stormwater control measures (SCMs) in terms of micropollutant load reduction. Data covers 12 management systems, in 9 diffe...
Fault-tolerant architectures are mandatory to ensure the robustness of autonomous robots performing missions in complex and uncertain environments. The first step of a fault-tolerant mechanism is the detection of a faulty behavior of the system. It is then important to provide tools to help robot developers specify relevant observers. It is moreove...
Local scour is the removal of soil around bridge foundations under the erosive action of flowing water. This hydraulic risk has raised awareness of the need for developing continuous monitoring techniques to estimate scour depth around bridge piers and abutments. One of the emerging techniques is based on monitoring the vibration frequency of eithe...

In the Lorraine area of eastern France, decades of iron-ore mining from 1850 to 1997 have left vast underground cavities beneath or in the vicinity of urban areas. Several major collapses occurred in the southern part of this iron-ore basin in the 1990s, after the mine closure and the flooding of underground mine workings. Following these large-sca...
The possibility of Land Viewer program based on space imagering from sentinel-2 using to detect and monitor forest fares paper. It has been established that 21 combinations of shooting channels allows choose the most suitable options for deteching forest fires as well as the area covered by the fire. The program allows, if registered, carry out the...
