| Abstract: | Landscape evolution models can be useful tools for the evaluation of rehabilitation designs for post-mining landscapes. When calibrated for the erodible material, landscape evolution models can predict sediment loss over entire landscapes (i.e. tonnes/hectare/year), method of erosion (i.e. slope wash, gullying) and also where on a hillslope erosion is likely to occur. The models provide the ability to examine simple hillslopes through to complex whole landscapes. These models can also be used for a probabilistic risk assessment of rehabilitation design for high-risk situations such as tailings dams. Importantly, unlike other erosion models they allow the eroded landscape to be visualised. This paper outlines the capabilities of the SIBERIA landscape evolution model for the rehabilitation of mining landscapes and proposes a probabilistic approach for risk assessment and site stability. |
