Summary: | The groundwater flow of a reclamation site in Alberta’s Oil Sands was modeled using the MODFLOW 3D
code. The site was simulated to determine the flow characteristics of a reclamation hummock. Such
hummocks are required to maintain a mounded water table to sustain plant life placed on top as a part
of reclamation. Sensitivity analysis was conducted initially by varying the water table depth. The
hydraulic conductivity of the material, and recharge were then varied, in addition to adding a low
conductivity cover layer, in order to monitor the water table response. Modeling found that a lower
than predicted hydraulic conductivity value would be required to maintain a desired mounded water
table at 1.5m depth. Additionally the hummock was found to be sensitive to flooding and drought
conditions. Design topography such as swales and ridges were found to function as desired, by acting as
areas of discharge and recharge respectively. |
