Appendix B Proposed structure of product 2.6.1 (surface water numerical modelling) and product 2.5 (water balance assessment)

2.6.1.1

Methods

This will be mostly generic text. Overarching information about how the groundwater and surface water models are linked is included here.

2.6.1.2

Review of existing models

Discussion of any models that have been used for regional coal resource development modelling.

2.6.1.3

Model development

If there is more than one model, include level 5 headings as follows. Not required if just one model.

2.6.1.3.1 Model #1

2.6.1.3.2 Model #2

2.6.1.4

Calibration

If there is more than one model, include level 5 headings as follows. Not required if just one model.

2.6.1.4.1 Model #1

2.6.1.4.2 Model #2

2.5.1.1

Spatial and temporal extent of the water balances

Temporal resolution: The water balance is reported over three 30-year periods, namely 2013 to 2042, 2043 to 2072 and 2073 to 2102, which align with the three global warming scenarios of 1.0, 1.5 and 2.0 °C.

Spatial resolution: This will vary by subregion, but a general principle is to report the water balance over the minimum possible area which incorporates all hydrologically connected cumulative impacts. Thus more than one might be required per subregion or bioregion.

2.5.2

Water balances

Suggestions for level 4 headings are either: inflows, consumptive use and discharge, or a subheading for each water management unit.

2.5.2.1

Reporting unit #1

Number of tables: Three tables will be needed for each spatial reporting unit – one for each of the three time slices. Each will contain results under the baseline, under the CRDP, and the difference.

Uncertainty: Within each table, for some outputs, three numbers will be required representing the median, 10th and 90th percentiles from the uncertainty analysis. For some outputs (e.g. rainfall) this will not be required.
