Geometric representations of major surface water features of Australia, such as rivers, lakes, reservoirs, dams, canals and catchments. Also includes hydrologic features such as catchment boundaries and drainage basins. <b>Value:</b> This data is not authoritative, but represent a valuable resource for visualisation, decision support and planning activities. <b>Scope:</b> This is a National dataset at resolution relevant for presentation of regional spatial data such as digital maps.

Accurate information about the extent, frequency and duration of forest inundation is required to inform ecological, biophysical and hydrological models and enables floodplain managers to quantify the efficacy of flood mitigation/modification activities. Open water classifiers derived from optical remote sensing typically underestimate or fail to detect floodplain forest inundation. This paper presents a new method for detecting forest inundation dynamics using freely available Landsat and Sentinel 2 data, referred to as short-wave infrared mapping under vegetation. The method uses a dynamic threshold that accounts for the additional shortwave infrared reflectance caused by the presence of tree canopies over floodwater. The method is demonstrated at five Ramsar listed River Red Gum floodplain forest wetlands in southeastern Australia. Accuracy assessment based on independent drone imagery from a wide range of vegetated wetlands showed an absolute accuracy of 67%–70% and a fuzzy accuracy of 81%–83%. We found the method is conservative, and underestimates inundation (16%–18%) but very rarely misclassifies dry pixels as inundated (0.3%–0.6%). When compared to river gauge data, the method shows similar trends to an open water classifier (i.e., the area of inundated vegetation increases with increasing river height). The method is conservative compared to lidar-based floodplain inundation models but can be applied wherever cloud-free scenes of Landsat or Sentinel 2 have been acquired, thereby enabling floodplain managers with the ability to quantify changes in inundation dynamics in places/time-periods where lidar is unavailable. <b>Citation:</b> Lymburner, L., Ticehurst, C., Adame, M.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the north Bowen Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the north Bowen Basin, including streamflow quality and quantity, inundation and climatological data. Most of the north Bowen Basin falls to the east of the Great Dividing Range within the Fitzroy River catchment. The basin also includes part of the Burdekin River catchment and small parts of the coastal catchments of Styx and Burnett river catchments. The data on the catchments overlying the north Bowen Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are available from the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Galilee Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Galilee Basin, including streamflow quality and quantity, inundation, and climatological data. The Galilee Basin straddles the Great Dividing Range and encompasses the headwaters of 9 major river basins, with the largest area underlying Cooper Creek, Diamantina River and Flinders River catchments. The Galilee Basin geological boundary also intersects parts of the catchment of the Burdekin River, Fitzroy River, Warrego River, Bulloo River, Paroo River and Condamine-Balonne rivers. The data on the catchments overlying the Galilee Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Cooper Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Cooper Basin, including streamflow quality and quantity, inundation, and climatological data. The Cooper Basin underlies 3 surface water catchments: the Diamantina River, Cooper Creek and Bulloo River. All 3 rivers follow a similar flow pattern, with most of the run-off generated in the higher rainfall headwater areas (outside the Cooper Basin) before flowing down into extensive floodplains and ending up in terminal lake systems. The data on the catchments overlying the Cooper Basin have been summarised at a point in time to inform decisions on resource development activities. Key data sources are the Water Monitoring Information Portal (Queensland Government), Water Data Online (Bureau of Meteorology), DEA Water Observations (Geoscience Australia) and Terrestrial Ecosystem Research Network.

Publicly available baseline surface water data are compiled to provide a common information base for resource development and regulatory decisions in the Adavale Basin region. This data guide captures existing knowledge of the catchments and watercourses overlying the Adavale Basin, including streamflow quality and quantity, inundation, and climatological data. The Adavale Basin underlies 3 main surface water catchments that contribute to Cooper Creek, including the Barcoo, Bulloo and Warrego rivers. The Adavale Basin geological boundary also intersects the upper parts of the Paroo River catchment and a small part of the Condamine-Balonne catchment. The data on the catchments overlying the Adavale Basin have been summarised at a point in time to inform decisions on resource development activities.
