Waste Rock Infiltration

The above problem illustrates the use of SVFlux in gauging the influence of precipitation events on a waste rock pile. The infiltration due to a precipitation event can be calculated. The problem also highlights the use of automatic mesh refinement to improve the accuracy of the wetting front calculations. It can be seen that the upper wetting front progressively moves down to meet the water table. The specific influence of precipitation events and evaporation can therefore be calculated.

Waste
rock flow is particularly difficult due to the granular nature
of waste rock and the steep unsaturated soil property functions.
SVFlux has benchmarked solutions to these difficult problems. In
the problem above, a coarse layer is layered with a fine layer
and a simulated rainfall is applied. The SVFlux seepage model correctly
assesses whether flow will be through the fine or the coarse layer.
The solution to this problem is benchmarked in the M.Sc. thesis
of James Wilson. Severe numerical difficulties were encountered
during the course of the 3-year thesis using other software. A
solution was achieved with SVFlux in a period of 3 days.
Model setup time: 2 days
Solution time: 28 minutes on PIII-1.0 GHz

| This
problem illustrates the ability of SVFlux to solve problems
involving layers of fine and coarse material. This structuring
of material is typical of the layering found in waste rock
piles but is difficult due to convergence problems. SVFlux
has benchmarked the solving of these difficult problems. The
example animation shows the fingering in of flow from an applied
rainfall event. The progressive mesh refinement is also shown
to follow the wetting front. |

| This
problem illustrates the use of SVFlux to track the infiltration
of water into a complicated layered waste material deposition.
The water will flow down the high-permeability layers to the
center of the deposition. |
