Landform Stability and Evolution
An understanding of the consequences of such responses can inform the design of stable landforms and their elements, such as soils and cover materials. Similarly, ongoing impacts leading to changes in the stability of a landform (e.g. subsidence), can be addressed by investigating the change in the landforms’ equilibrium with the environment.
The further the landform is from a state of equilibrium, the more intensive the processes will be
Current CMLR research in landform stability includes the optimisation of cover design under various climatic conditions for mine closure planning. Ecohydrological concepts for revegetation are built-in to improve the level of certainty for the successful establishment of the desired vegetation community. Hydrogeochemical parameters, from leaching tests in the laboratory, allow the creation of trajectories of the long-term behaviour of the materials under investigation. This work is closely linked to Environmental Geochemistry and Soil-Plant Systems research. In addition, advanced monitoring technologies utilised by CMLR enable the quantification of these landform processes in space and time.
