This paper presents the results of integrated hydrologic modeling to demonstrate the role of soil freeze-thaw in hydrological response of reclaimed oil sands landforms. In this case the proposed land-reclamation involved backfilling an open-pit mine with a mixture of tailings materials. The upland portion of the reclaimed land is made-up of a series of hummocks forming a gently sloping hummock/swale system which should direct water flow to a low-lying area connected to the reclaimed landform outlet. The entire system is discretized into 13 numerical layers, and over 1.1 million computational nodes.
The results provide a strong argument for the inclusion if winter processes and coupled heat dynamics for detailed studies of integrated hydrologic processes in the Athabasca Oil Sands region.
