The surface water model nodes are the locations where streamflow predictions are made. In general, these nodes are located either:
- at streamflow gauges
- above major confluences
- immediately below proposed mine developments
- at locations required for receptor impact analysis.
The 63 model nodes in the Hunter river basin include 34 streamflow gauging locations and 29 other locations (Figure 4). Nodes are numbered by location along the stream network from downstream to upstream. There are two model nodes in the Wyong river basin.
For ease of reporting (see Section 2.6.1.6), model nodes have been numbered from the most downstream node upstream, commencing with node 1 on the Hunter River at Greta. Numbers progress along the main river channel and up each tributary with a node in the order that tributaries meet the main river channel. This is illustrated in Figure 5. In the Wyong river basin, numbering starts at node 64 and completes with node 65.
The extent of the coal resource developments in the coal resource development pathway (CRDP) is the union of the extents in the baseline and in the additional coal resource development (ACRD).

Main figure for the Hunter river basin; inset of the Wyong river basin. Model nodes number from most downstream node upstream. Blue nodes correspond to stream gauging stations; orange nodes correspond to model-specific nodes. The thicker blue line depicts the regulated part of the river system.
