History of water use in the Perth—Bunbury region

History of water use in the Perth—Bunbury region

This is a slight modified extract from the report – Lund, M.A. and Martin, H.C. (1996) Historical association of wetlands and rivers in the Perth-Bunbury region. Water Resource Technical Series. Water and Rivers Commission Report WRT3. Perth, Western Australia. The full report also includes information on each Shire and Suburb in the Perth-Bunbury region. Early Exploration The Dutch were the first Europeans to discover Western Australia (WA) in 1616 and over subsequent years mapped the coast and lost many ships to reefs. The Dutch found that the land contained little in terms of accessible supplies and the Aboriginal people were…

Geochemical Modelling of Pit Lake Water Chemistry to Support Management Decisions

Geochemical Modelling of Pit Lake Water Chemistry to Support Management Decisions

Mike Mueller (Hydrocomputing, Germany), Katja Eulitz (Hydrocomputing, Germany), Clint McCullough (MiWER), Mark Lund (MiWER)     How does pit lake water quality and depth change under different management scenarios? Stage 1. Selection of appropriate model This model will maximise the use of the currently available data for model creation and validation. The current preference is not to focus on a single pit lake and model in detail but develop a simpler model that can be easily applied to cohorts of Collie pit lakes identified by the inventory collection and conceptual modelling. This general model would be less detailed but more suited to…

Conceptual Modelling of Pit Lake Processes and Ecological Risk

Conceptual Modelling of Pit Lake Processes and Ecological Risk

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…
