## **Abstract**
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.
The final Zone of Potential Hydrological Change (ZPHC) is a union of the groundwater ZPHC and suface water ZPHC, which in turn were derived from groundwater and surface water impact modelling. The groundwater component of the ZPHC is where the the probability 5% or greater of equalling or exceeding 0.2m drawdown and is derived from the 95th Quantile layer.
The surface water component of the ZoPHC is derived from the reaches that are deemed impacted from the surface water modelled (sometimes referred to as Step 1 reaches) as well as additional non modelled reaches that are deemed to be potentially impacted due to interactions with the GW drawdown layer (aka Step 2) or proposed mine operations at the surface (aka Step 3). How these are derived are expanded on in the History section of the metadata.
The SW ZoPHC is created from AU cells that intersect any of the impacted stream lines (from steps 1-3 above) as well as those which intersect GDE landscapeclass singlepart polygons withing 150m of the impacted stream lines.
Some manual post processing edits were undertaken to remove anomalous AU cells. Importantly the ZoPHC_source_AU_master contains the reach id to which an Assessment Unit (AU) is allocated.
Important note: an AU is only allocated to a reach if it is within the SW ZoPHC
## **Dataset History**
GW ZoPHC
A CON statement in ArcGIS Spatial Analyst was used to extract the area of the 95th quantile raster layer where drawdown was >= 0.2m. The resulting integer zone grid was vectorised into a shapefile. An anomalous zone on the SW boundary of the subregion that was an artefact of the modelling was deleted. The result is the GW ZoPHC
SW ZoPHC
Potentially impacted reaches were extracted from Interpoloted Reaches. These are line features where "SW_ZoPHC" = 'yes' or 'part'. From these extracted "impacted" reaches, the line features classified as "part" were manually edited (cut) according to the description in the HRV (Hydrological Response Variables). This typically involved trimming the line back only to that in or downstream of the GW ZoPHC extent. Also some "part" impacted line features were cut where they intersected existing (i.e. baseline) open cut pits (OC). . Streams that where inside or downstream of the GW ZoPHC were selected and underwent the same Baseline open pit excision process as above.
The final Zone of Potential Hydrological Change (ZPHC) is a union of the groundwater ZPHC and surface water ZPHC, which in turn were derived from groundwater and surface water impact modelling.
