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

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
