On the Origin and Distribution of Internal Erosion Signatures in the Floodplain Protected by River Dikes Open
The subsoils of river dikes are often composed of highly permeable and low‐density river sediments. Thus, erosion signatures (leaks, sand boils, sinkholes) can appear in the protected floodplain during floods, highlighting the development …

Measuring and Predicting the Angle of Repose of Granular Matter from Clump and Potential Particles DEM Approaches Open
The angle of repose (AoR) is a widely employed measurement for granular materials that is currently used by various industries to characterise the behaviour of powders, soils and grains. This study proposes a new measurement technique for …

Sedimentation of short-lived fluid-solid suspensions Open
In this study, we propose a particle sedimentation/aggradation law for homogeneous concentrated suspensions. This law, valid in the Stokes flow regime, can be used to describe the sedimentation process observed in short-lived rapid flows, …

On Internal Erosion of the Pervious Foundation of Flood Protection Dikes Open
This work focuses on the mechanisms that trigger internal erosion of the pervious foundation of flood protection dikes. The origin of these permeable layers is generally attributed to the presence of a paleo-valley and paleo-channels fille…

Learning for Air Traffic Management: guidelines for future AI systems Open
The SESAR-funded Modern ATM via Human / Automation Learning Optimisation (MAHALO) project recently completed two years of technical work exploring the human performance impacts of AI and Machine Learning (ML), as applied to enroute ATC con…

Field Testing of the Overflow Erosion of Rhone River Levees Open
It is important to quantify the soil resistance against erosion caused by the overflow of dikes and levees. Small-scale tests are not recommended, as they do not provide a correct representation of the actual soil in place and do not take …

Innovative geocomposite for dredged sediments depollution Open
In France, sediments from river dredging are considered as waste. Without any special treatment, they must be stored in landfills. The dredged sediments of our area of study (North of France) are polluted with trace metals (antimony and zi…

Perspective: Lessons Learned, Challenges, and Opportunities in Quantifying Cohesive Soil Erodibility with the Jet Erosion Test (JET) Open
Highlights The JET is a key instrument for in situ and laboratory measurement of soil erodibility. Operation and reporting guidelines are needed to ensure consistency across JETs and applications. JET design improvements and hydrodynamic s…

Extending the Shields criterion to erosion of weakly cemented granular soils Open
This contribution tackles the issue of incipient conditions for initiation of erosion by a fluid flow at the surface of cohesive materials. To this end, a typical assessment procedure consists of subjecting a soil sample to progressive hyd…

Mesoscale inertial transition in granular materials Open
Granular assemblies can experience complex failure patterns along a given loading path, with a distribution of ephemeral inertial events marked by local outbursts in kinetic energy. However, investigating such mechanisms appears to be nece…

Rattlers’ involvement for possibly looser critical states under higher mean stress Open
The critical state of a granular material made of rounded tetrahedral particles is studied through DEM simulations of triaxial compressions. A minimum number of 7,500 particles is first obtained as the representative volume element (RVE) f…
