Clint McCullough (MiWER), Mark Lund (MiWER) Conceptual modelling to better understand ecological risks posed by pit lakes To ensure greatest scientific robustness of conceptual models we held a site visit and workshop in Collie with an expert panel of scientific researchers and managers from universities and State regulatory staff to best understand how these processes are likely working in different pit lakes. This workshop identified conceptual model needs e.g., a carbon cycling model and an acidity budget model. The intent is to then present the conceptual models as diagrammatic representations highlighting the nature of relationships between parameters and processes. These models will also…
