Groundwater divide water flow direction

## **Abstract** \n\nThe 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.\n\nThe processes undertaken to produce this derived dataset are described in the History field in this metadata statement. \n\n\n\nGroundwater divide shows water flow direction based on groundwater Potentiometric surface plots (6c212a1a-658c-41de-92a7-6054349a848b) per aquifer.\n\n## **Purpose** \n\nDataset shows the different flow directions overlying the the Eromanga Basin aqufers.\n\n## **Dataset History** \n\nIndicates the direction of water flow using the Potentiometric head difference v01(6c212a1a-658c-41de-92a7-6054349a848b).\n\n\n\nA shapefile was created for the use of showing water flow direction based on groundwater Potentiometric surface plots (6c212a1a-658c-41de-92a7-6054349a848b) per aquifer\n\n\n\nMethod:\n\n\n\n\\* A new line shapefile was created with no content.\n\n\\* The shapefile was then populated in an ArcMap editing session by digitizing polylines to show Groundwater divide .\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2015) Groundwater divide water flow direction.
