Seepage Induced Geotechnical Instability
Workshop exploring recent developments considering seepage and instability in cohesionless soil
Imperial College London, UK: 31st Aug – 1st Sept 2017
This workshop was run in conjunction with the ISSMGE Technical Committees: TC 105 Geo-Mechanics from Micro to Macro, TC 201 Dikes and Levees, TC 213 Scour and Erosion. The workshop launched the EPSRC funded research project: Particle-scale invesitagion of go Delegates included academics, civil engineering consultants and representatives from some UK dam owners. To give a flavour of the workshop the schedule is given below. Where possible, the schedule includes links to the presentation slides.
