SYD Dryland Diffuse Groundwater Recharge v01


The 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.

This dataset contains four rasters of groundwater recharge over the Sydney Basin. There is a deterministic "best" estimate of the recharge and there are 3 percentiles (5th, 50th and 95th) from a probabilistic estimate of the recharge over the Sydney Basin.


This dataset was created as an input into the numerical groundwater modelling.

Dataset History

This dataset was created using regression equations developed from the point estimates of recharge using the chloride mass balance. The regression equations were created from a relationship between the annual average rainfall and average annual recharge for different surface geology groupings.
