The crust beneath the InSight lander on Mars is altered or fractured to 8–11 km depth and may bear volatiles, according to an analysis of seismic noise and wave scattering recorded by InSight’s seismometer.
Nous partageons et interagissons tous les jours, parfois sans le savoir, avec les sites naturels et les ouvrages du génie civil qui nous entourent. Pourtant le fonctionnement de ces milieux est assez méconnu ce qui limite nos possibilités en matière d'occupation du territoire et d'emploi des infrastructures. Ce mémoire d'HDR retrace les recherches ...
This article presents a review of the use of unmanned aerial vehicles (UAVs) in the context of geohazards. The pluri-disciplinary role of UAVs is outlined in numerous studies associated with mass earth movements, volcanology, flooding events and earthquakes. Scientific advances and innovations of several research teams around the world are presente...
En France, les digues de protection fluviales s'étendent sur plus de 8 600 km. Ces ouvrages sont très hétérogènes, de par leur mode de construction et leur historique (ruptures et réparations, rehausses. . . ). Les ruptures d'ouvrages sont susceptibles de mener à des conséquences désastreuses telles que des pertes humaines, économiques, environneme...
The identification of the subsoil constitutive materials, as well as the detection of possible interfaces and anomalies, are crucial for many site characterization applications. During investigation campaigns, complementary geophysical and geotechnical methods are usually used. These two sets of methods yield data with very different spatial scales...
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...

To prevent catastrophic consequences imputed to levee breakage, the identification of the subsoil constitutive materials, as well as the detection of interfaces and anomalies are crucial. During investigation campaigns, complementary geophysical and geotechnical methods are usually used. These two sets of methods provide data with very different sp...
