Spatial and temporal modelling domains

As reported in Section 2.3.4 of companion product 2.3 for the Clarence-Moreton bioregion (Raiber et al., 2016), there is no coal seam gas (CSG) development in the baseline coal resource development for the Clarence-Moreton bioregion and the only additional coal resource development in the bioregion is located in the western part of the Richmond river basin. Therefore, the modelling in the Clarence‑Moreton bioregion has been restricted to the Richmond river basin.

The surface water modelling domain adopted in the bioregional assessment (BA) for the Clarence-Moreton bioregion includes the entire basin of the Richmond River above Casino, as well as the neighbouring areas to the east (Leycester Creek) and to the south (Shannon Brook and Myrtle Creek) (Figure 4). The tidal limit of the Richmond River extends to just below the gauging station at Casino. The modelling domain has been restricted to the areas of non-tidal influence.

Simulations from 2013 to 2102 were undertaken for both baseline and coal resource development pathway (CRDP). However, the period from 1983 to 2012 is also modelled and acts as an extended warm-up period to reduce any bias in the predictions from starting conditions.
