EPSRC Grant Success: Particle-Scale Investigation of Seepage Induced Geotechnical Instability


Dr Lis Bowman, in collaboration with Dr Catherine O'Sullivan (Imperial College London) and Dr Jonathan Black (University of Sheffield), has been awarded £390k from the EPSRC to study internal instabilities in geotechnical infrastructure.  

The project will focus on particle-scale mechanisms, notably how particle movement may be triggered by seepage forces, and how this is dependent on the stress state of the soil mass.  The work is designed to improve hydraulic failure design guidelines via novel physical experiments using transparent soil and numerical Discrete Element Method (DEM) simulations coupled with computational fluid dynamics (CFD).
