Doubly vergent wedges

These two chapters investigate the evolution of doubly vergent wedges using clustered particles for constant friction parameters. Chapter 4 looks at the Normal Variability expected within the same boundary conditions for different packing structures. Chapter 5 incorporates a simple erosional algorithm where particles are removed if they exceed some threshold elevation, given by a multiple of the incoming thickness of material, H.
