HUN SW Modelling Reaches and HRV lookup 20171121 v05


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.

Contains line shapefiles and an excel spreadsheet and csv text file lookup table. The line shapefile derived from the Geofabric Surface Water Network streams (source data) and spatially represents the reaches described in the accompanying lookup table so that surface water modelling based Hydrological Response Variables (HRVs) can be applied spatially along stream lengths. Differs from previous versions in that some reaches previous designated as Ph (potentially impacted but not quantified) have now been assigned to a surface water modelling node. They include reach sections with no modelled change, no inferred change etc and thus extend outside the SW ZoPHC. All reaches described in interpolations spreadsheet are intact in that they extent outside the ZoPHC and event the PAE. Also included are the "rch_200" and "rch_300 reaches". These are reaches identified as additional potentially impacted reaches over and above those described by the interpolations spreadsheet. Also included is the revised reach to SW node lookup table for the HRVs.

Dataset History

Line segments from the Geofabric Network Streams source dataset were grouped into reach sections based on descriptions in the accompanying interpolations lookup table (supplied by Surface Water Modelling team) using the surface water node locations and described river junctions and other defined locations as spatial reference. Reaches were given a unique ID and dissolved into a multipart lines. In addition to the reaches described in the interpolations spreadsheet, additional reaches were identified (using the riverine perenniality classified stream network) as subject to potential hydrological change. These were non-ephemeral streams (LC_id = 22, 23, 25) rising out of or intersecting the groundwater zone of potential hydrological change (rch_200) and ephemeral reaches (LC_id = 24) rising out of or intersecting baseline mine pits (rch_300).
