In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...
Ce travail s'inscrit dans le cadre de la gestion des eaux pluviales en ville. Il porte sur le transfert de nanoparticules manufacturées dans un sol macroporé pour prendre en compte la présence d'hétérogénéités dans les sols naturels et les écoulements préférentiels induits. Il inclut un ensemble d'expérimentations en colonne de laboratoire permetta...
This paper is devoted to the investigation of the density sorting of grains using water jigging. Experiments achieved in a laboratory scale water jig for two initial binary bed configurations are studied and compared to numerical results. The vertical composition of the deposit is estimated after different number of water pulses to represent the so...

The hydraulic conductivity of saturated clays is commonly determined either directly by monitoring water flux or indirectly based on Terzaghi's consolidation equation. Similar results are generally obtained from the two methods, but sometimes a significant difference can be observed, in particular for expansive soils. In this study, the hydraulic c...
A series of one-dimensional incremental load consolidation-hydraulic conductivity tests was performed on reconstituted clays. Based on these tests, together with the test data compiled from the literature, the quantitative interrelation between the variation of hydraulic conductivity in the vertical direction with void ratio and the compression beh...
Les pieux en bois ont été très utilisés en Europe plus particulièrement en France mais le retour d'expérience sur l'évolution de leur dégradation avec le temps est très faible. Ce stage a donc été réalisé pour étudier la cinétique de dégradation du bois en condition d'immersion. Dans ce rapport, nous avons tout d'abord effectué une recherche biblio...
The Task Group 2 of the RILEM Technical Committee 264-RAP on non-cold recycling identified the need to gather some insights about possible durability issues associated with the combination of Warm Mix Asphalt (WMA) and of Reclaimed Asphalt (RA) in order to prioritize the characteriza-tion or research needs for relevant damage types. For this purpos...
Les processus d'affouillement sont une cause importante de destruction des constructions (ouvrages d'art, ouvrages en terre et bâtiments) notamment lors des crues majeures. La prise en compte de ces phénomènes d'érosion reste trop empirique, notamment parce qu'ils sont particulièrement complexes et font intervenir de nombreux champs disciplinaires ...
