The observations analysis, statistical analysis and interpolation product for the Clarence-Moreton bioregion describes the information necessary to better understand and model the areas where coal development is possible. This provides a quantitative understanding of the Clarence-Moreton bioregion by analysing the observed data and, where required, estimating additional data for locations where data are sparse.
The product presents the following datasets and analyses:
- geography: all geographic data specific to the Clarence-Moreton bioregion were obtained from state or national datasets.
- geology: the major geological data sources in the Clarence-Moreton bioregion are geological maps, lithological and stratigraphic data from the Queensland and New South Wales groundwater databases, stratigraphic records from exploration wells and geophysical data.
- hydrogeology and groundwater quality: mean groundwater levels, depths to groundwater and the associated uncertainties were determined for various aquifers of the Clarence-Moreton bioregion.
- surface water hydrology and water quality: there are 12 gauging stations with more than 10 years' reliable daily streamflow data between 1980 and 2012.
- surface water – groundwater interactions: two principal categories of surface water – groundwater interactions have been identified: (i) stream–aquifer interactions, and (ii) aquifer–wetland interactions.
This product includes an assessment of data errors and uncertainties; the spatial and temporal resolution of observations over space and time; and algorithms used in the development of derived datasets. Data gaps are identified.
Relationship to other products
This product on observations analysis, statistical analysis and interpolation is part of a series of model-data analysis products (Component 2), which describe the hydrological relationships between coal resource development and potentially impacted water resources and water-dependent assets in the bioregion. This product informs impact and risk analysis (Component 3 and 4) products on the risks to and potential impacts on water resources and water-dependent assets, such as bores and habitats.
