  • Traditionally, multi-disciplinary modelling exercises involve one discipline mechanistically using the output from a black-box model developed by another discipline. To address this deficiency, the research uses techniques relatively new to the geotechnical community, such as System Dynamics (SD) and Causal Loop Diagramming (CLD). SD and CLD method provide a framework under which both technical and non-technical stakeholders can create shared understandings of key issues in a collaborative manner. In this project, the qualitative stage of modelling uses a series of CLDs to visually describe the interaction between a reclamation capping layer and the tailings substrate. Then the quantitative stage translates those CLDs into numerical simulations inside GoldSim, an object-oriented simulation engine. Finally, a consolidation sub-model and a unsaturated flow sub-model were combined to simulate soil water dynamics in the reclamation capping layer. Preliminary simulation results and some lessons learned will be presented and discussed.
