Dataset: GAL Surface Water Reaches for Risk and Impact Analysis 20180803



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.

Dataset History

Stream network constructed and defined using datasets shown in the Lineage.

The stream network constructed using surface water nodes to define reaches and the the classification was assigned by using the data from the stream network from the lineage and then assigned the following classfication:

  1. surface water change due to hydrology

  2. no change modelled at link node within PAE

  3. modelled no change at link node

  4. modelled change at link node

  5. assumed change due to proximity to mine pit
  6. assumed change due to hydrology

Further tie-breaks were decide based on stream order or stream segment length.
