HUN Surface Water Model Nodes 20170110 HRV Ratios v01

Abstract

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.

The dataset consisits of three shapefiles containing point features of Hunter subregion surface water nodes with summarised hydrological response variables (HRV) data for zero flow days (ZFD), high flow days (HFD) and annual flow (AF). Maps use the ratio data for mapping with classes.The changes in the number of ZFD, HFD and AF due to additional coal resource development relative to the interannual variability flow days under the baseline has been adopted to put some context around the modelled changes. This ratio of absolute maximum change and variability range (5th, 50th and 95th percentiles) has been calculated qualitatively for each surface water model node .

Dataset History

These shape files bring model node spatial location and HRV ratios together.

The input surface water HRV shape file (HUN_SW_Modelling_Reaches_and_HRV_lookup_20171121_v05 (GUID: 8c330d59-2ecc-4c35-8f9e-68b91a4ae98a) has been augmented with data from the spreadsheet (HUN_HRVs_scatterplots_version3.xlsx, GUID:1c0a19f9-98c2-4d92-956d-dd764aaa10f9), by linking to the node number.

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 <3 (i.e. 3 is a blue dot, not an open circle)

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

pmax for AF <1 percent (note this is pmax NOT amax)
