Robbins, B.A. (author), van Beek, V.M. (author)A novel laboratory device is presented, in which the process of backward erosion piping is observed in cylindrical sand samples oriented horizontally. The cylindrical shape of the testing device constrained the location of the erosion path to the top of the sample, thereby allowing pore pressure measurements to be made in both the eroded pipe...conference paper 2017

Bittner, T. (author), Bore, T. (author), Scheuermann, A. (author), Bajodek, M. (author), Witt, K.J. (author)The rearrangement of soil particles during erosion, which is basically a transient mixing of base and filter particles, is accompanied by changes in porosity, leading to overall settlements which frequently can be severe for geotechnical structures such as levees. Therefore, not only the geometric and hydraulic boundary conditions, but also...conference paper 2017

Resistance to erosion of lime treated soils and perspectives for coastal dikes: (Paper and Abstract)De Baecque, M. (author), Chevalier, C. (author), Palma Lopes, S. (author), Le Feuvre, M. (author), Reiffsteck, P. (author), Charles, I (author), Herrier, G. (author)Fluvial and coastal dikes are the primary protection for human life from natural hazards like flooding or wave action. To build these hydraulic earthworks requires many materials with specific performances in terms of workability, mechanical strength, permeability, resistance to erosion, etc. Very often, local material does not meet requirements...conference paper 2017

Rönnqvist, H. (author)Swedish embankment dams are usually constructed with core soils of glacial till. A widely graded soil sourced from moraine deposits, till comprises many fractions, from silt and sand to gravel and stones, all crushed and mixed by the action of glaciation. Interestingly, this type of soil is remarkably similar to that in other parts of the world...conference paper 2017

Bezuijen, A. (author)The earliest relation describing the risk of backward erosion piping, from Bligh in 1915, calculates an overall gradient over the dike. This gradient should be lower than a certain value depending on the material of the dike foundation for the dike to be safe. Later developments rationalize this number, showing the influence of grain size,...conference paper 2017

Benamar, A. (author), Azirou, S. (author), Tahakourt, A. (author)Dam filters are mainly designed using filter criteria based on the grain size distribution. The main design criteria against which performance is assessed are a criterion for retention of fine particles. The characteristic size of finer fraction influences the size distribution of the filter pore and hence the retention capacity of flowing...conference paper 2017

Vandenboer, K. (author), van Beek, V.M. (author), Bezuijen, A. (author)Backward erosion piping is an important failure mechanism for water-retaining structures, a phenomenon that results in the formation of shallow pipes at the interface of a sandy or silty foundation and a cohesive cover layer. Although the pipe depth reveals a lot of information on the backward erosion process, it has never been measured...conference paper 2017

Di Pietro, P. (author)Recent studies show an increase in the population of beavers, nutria and other rodents in vast regions of central Europe over the last 15 years. Unfortunately, this caused in many instances considerable damage on large rivers along dykes and earthworks in the floodplain areas, leading to an increased risk of bank failures. However, most of these...conference paper 2017

Marot, D. (author), Bendahmane, F. (author), Andrianatrehina, R. (author), Gelet, R. (author)Suffusion, one of the main internal erosion processes, selectively erodes the fine particles which move through the voids formed by the coarser particles. In the literature, the mechanical consequences of suffusion on soil were investigated by several researchers. However, no general conclusion can be drawn because the already published results...conference paper 2017

Li, S. (author), Russell, A.R. (author), Muir Wood, D. (author)Results of an experimental investigation are reported, conducted to study the stress-strain behavior of a soil having undergone different amounts of internal erosion. The soil used is gap-graded and cohesionless comprising silt, sand and gravel. Internal erosion tests and subsequent triaxial tests are performed in a specially designed apparatus...conference paper 2017

Seblany, F. (author), Homberg, U. (author), Vincens, E. (author), Winkler, P. (author), Witt, K.J. (author)Granular filters are materials used to avoid mass transport under seepage flow. They are installed in zoned dams or on the downstream slope of levees to prevent the wash out of soil particles through the core of the earth structures or through its foundation. This migration is stopped if the particles are blocked on their pathway by a...conference paper 2017

Koelewijn, A.R. (author), Bridle, R. (author)Dams and dikes are both water-retaining earth embankments. These are vulnerable to internal erosion but specific differences lead to varying vulnerabilities to different types of internal erosion: • Dams are usually zoned, with potential filtering capability to arrest piping if it is initiated, while dikes are more commonly unzoned and incapable...conference paper 2017

Bas, G. (author)Industrial systems increasingly need to become more resilient to developments in their environment. To take the right decisions and improve their resilience, those companies need insight into the effects of resilience-enhancing actions. A substantial part of those actions' effects follow from the adaptation of the focal company's environment in...doctoral thesis 2017
