Abstract
This dataset was derived by the Bioregional Assessment Programme. The parent datasets are identified in the Lineage field in this metadata statement. The process undertaken to product this derived dataset are described in the History field in this metadata statement.
This dataset was created in order to calculate the steady-state drawdown extent for potential CSG developments in the Cooper subregion. The calculations are made using the de Glee method, as described in Krusemann (1994) in accordance with the SA Far North Water Allocation Plan (2009) explanation document. The data was created as part of the conceptual modelling for causal pathways to assess the potential for CSG development-related impacts to propagate via groundwater drawdown.
Dataset History
The dataset assumes water production rates for CSG in the Cooper subregion based on production rates in other eastern Australian Permian CSG fields, reported in
Onshore co-produced water: extent and management (http://data.bioregionalassessments.gov.au/dataset/6b3d8096-f09d-40a2-b5ee-09c9f8b9bdfc); and

Distance-drawdown was calculated using the de Glee method for steady-state drawdown described in Krusemann (1994) Analysis and Evaluation of Pumping Test Data. (http://data.bioregionalassessments.gov.au/dataset/c66b744e-e9bb-4d88-a82c-a6593efe91d2)
