Short Course – ACG



Geotechnical systems, are required to perform safely throughout their service life, which can span from decades for levees to in-perpetuity for TSFs. The conventional design practice by geotechnical engineers for these systems utilises the as-built material properties to predict its performance throughout the required service life. The implicit assumption in this design methodology is that the soil properties are stable through time. This is counter to long-term field observation of these systems, particularly where ecological processes such as plant, animal, biological and geochemical activity is present. This course presents an integrated perspective and new approach to this issue; considering ecological, geotechnical and mining demands and constraints.
