Effects on report and presentation
Data includes
Base data – topography, roads, railways, streamsLand use, land management unitsBorehole logs, cross sections, and geological surfacesGroundwater and surface water monitoring recordsHydraulic property informationWater usage datasetsOthers
Data includes (approximately)
22.8 million records for surface waterlevels, flows, temperature
25,000 individual boreholes172,000 facies interpretations22,800 stratigraphic records1.1 million points from geological surfaces
6.5 million daily rainfall records
Physical catchment
Regional Geology
PEL areas and bore locations
Coal exploration areas
Stratigraphic bore locations
Rainfall stations
Rainfall analysis
Other layersEvaporation Land management units
Land use
Bore yields from drilling records
GW Quality
Groundwater level bores
Groundwater contour levels and flow directions
SW gauging stations and catchments
GW-SW interaction
Data gapsSeveral data gaps have been identified e.g.
Dataset biased towards shallow alluvial areasMinimal hydraulic test data for hard rock unitsLittle deep drilling to east of the Hunter-Mooki faultInconsistencies with water usage information
Data gaps are usual in large projectsWill not prevent construction of a model
Values from literature for areas with no dataUse model to identify areas for further studyUpdate the model when new data become available
