Dataset: Namoi drawdown exceedance probabilities for economic asset bores



This dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. Figures using these data were created using the Python scripting environment. Output produced probability exceedence curves of drawdown for economic bores in the Namoi assessment area.


This dataset was created to draw plots of cumulative areas of groundwater drawdown in the regional watertable aquifer corresponding to economic asset bores.

Dataset History

Element level data for economic bore assets were extracted from the Namoi asset database and stamped with corresponding zone information. Drawdown values from drawdown model grids were extracted to bore points and resulting table was exported to a text file. A Python script then plotted cumulative drawdown for bores within the zone of potential hydrological change for 6 groundwater management units.
