This section summarises the key steps taken in developing the surface water models for predicting the hydrological impacts of coal resource development in the Gloucester subregion. It includes discussion of the spatial and temporal modelling domains, the spatial resolution of the modelling, the development of a future climate trend, the development of time series of open-cut coal mine footprints, and the estimation of additional coal resource development (ACRD) impacts on streamflow.
The modelling domain comprises the Gloucester and Karuah river basins and includes 34 model nodes at which daily streamflow predictions are produced. The model simulation period is from 2013 to 2102.
Seasonal climate scaling factors from the CSIRO-Mk3.0 global climate model are chosen to provide a trended climate input over the course of the simulation period. These result in a reduction in mean annual precipitation of 0.4% per degree of global warming.
