This dataset was derived by the Bioregional Assessment Programme from 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.


Three shapefiles containing point features of Namoi subregion surface water nodes with summarised hydrological response variables (HRV) data for zero flow days (ZFD), high flow days (HFD) and annual flow (AF).

## **Purpose** 

Created to facilitate NAM 3-4 product maps.

## **Dataset History** 

The input surface water HRV shape file (AWRAR_NAM_reaches_V2 (GUID: 433a27f1-cee8-499e-970a-607c6a25e979) has been augmented with data from the spreadsheet (NAM_HRVs_interperiod_scatter_spatial_plot_data_v3), by linking to the node number.

For the Namoi subregion an extra step was required as the node number in the shapefile are not the same as the spreadsheet, so there was a linking table (gauge_node_relation.xlsx).


For each dataset, a new shapefile was produced - zero flow days (ZFD), high flow days (HFD) and annual flow (AF).


The data taken from the spreadsheet was:

ZFD. ZFD_corrected worksheet for ratio data with p_max data coming from ZFD worksheet.

HFD. FD_corrected worksheet for both ratio and amax data

AF. AF_corrected worksheet for both ratio and amax data


Maps use the ratio data for mapping with classes shown on maps except where the following was true, the ratio was replaced with 'no significant change'


amax for LFD &lt;3 (i.e. 3 is a blue dot, not an open circle)

amax for FD &lt;3 (i.e. 3 is a blue dot not an open circle)

pmax for AF &lt;1 percent (note this is pmax NOT amax)
