Modelling mechanical consequences of erosion
This paper presents the results of 2D discrete element modelling tests investigating suffusion (internal erosion), which arose from involvement with BCHydro concerning modelling of internal erosion at the WAC Bennett Dam. This process is difficult to reproduce in the laboratory and cannot be generated in tests with high hydraulic gradient or by reconstituting samples with narrowed grading. The results in the paper provide, therefore, a unique set of results which can be used to validate constitutive modelling strategies. The findings have been used by others (e.g Ficher (2013), Géotechnique, 63, 118-128) to validate alternative constitutive models for erosion.
