Some input parameters of the UBCSAND model.

Material zone	Material type
2, 6	Soft sand tailings	18.6°	120	36	0.95	6
3, 8	Layered sand tailings	22.6°	120	36	0.90	6
5, 7	Compacted sand tailings	26.8°	120	72	0.86	8

Note: is the peak friction angle, is the elastic shear modulus number, is the plastic shear modulus number, is the failure ratio, and is the corrected standard penetration test value of the soil.
