HUN Streamflow Baseflow Analysis

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the Streamflow data and locations for selected gauges in the Hunter subregion dataset. The source dataset is 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.\n\n\n\nHUN Streamflow Baseflow Analysis\n\n\n\nBaseflow Index (BFI) was derived for a number of Hunter gauging stations. They are created from synthesised data based on the New South Wales Office of Water (NOW) hydstra surface water database.\n\n\n\nThe BFI is a measure of the proportion of the river runoff that derives from stored sources; the more permeable the rock, superficial deposits and soils in a catchment, the higher the baseflow and the more sustained the river's flow during periods of low rainfall.\n\n\n\nData was extracted from the Hydstra format to .csv files for surface water sites within the Hunter region. Data were presented as a chart in the context report.\n\n## **Dataset History** \n\nHUN Streamflow Baseflow Analysis\n\n\n\nBaseflow Index (BFI) was derived for a number of Hunter gauging stations.
