DamWalls: A barrier of earth and rock, concrete or masonry constructed to form a reservoir for water storage purposes or to raise the water level. Rapidline: An area of broken, fast flowing water in a watercourse, where the slope of the bed increases (but without a prominent break of slope which might result in a waterfall), or where a gently dipping bar of harder rock outcrops. Spillway:A channel or duct formed around the side of a reservoir past the end of the dam, to convey flood discharge from the watercourse above the reservoir into the watercourse below the dam. Cliffline: A high, steep, significant or overhanging face of rock. Levee: A low earth wall erected to restrain flood waters or to contain irrigation water. Shoreline and Shoreline Junction: The boundary defining the division of the Commonwealth of Australia into State/Territory administrations. Tunnel: An artificial underground or underwater passage carrying a railway or road.</SPAN></P></DIV></DIV></DIV> We request attribution as © Commonwealth of Australia (Bureau of Meteorology) 2022 Environmental Prediction Services, Water Analysis Bureau of Meteorology, Community Services Group GPO Box 378 CANBERRA ACT 2601 AU ahgf@bom.gov.au Cliffline Dam Walls Shoreline Junction Tunnel Spillway Rapidline Shoreline Levee cliffline dam walls shoreline junction tunnel spillway rapidline shoreline levee cartography Licenced for use under Creative Commons Australia Attribution <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Creative Commons Attribution</SPAN><SPAN> V4.0 (CC BY 4.0)</SPAN></P></DIV></DIV></DIV> ESRI ArcCatalog 10.3.1.4959 publication date 112.92137 153.63857 -44 -8.93333 A composited set of features that potentially cross or obstruct streams. 1 113.647200 153.092270 -10.705490 -36.537760 Hydrology Lines other than mapped streams, canal lines and water pipelines Geoscience Australia has aggregated best available multiscale (1:25,000-1:250,000) jurisdictioanl datsets. As such where known each individual feature has been attributed with a relevant planimetric accuracy 1) AusHydro V2 Surface Hydrology dataset is loaded into the Geofabric development GIS environment. 2) Feature classes from AusHydro V2 are recomposed into composited Geofabric hydrography dataset feature classes in the Geofabric Maintenance Geodatabase. 3)These are assigned unique Hydro-IDs using ESRI ArcHydro for Surface Water. 4) Feature classes from the Geofabric Maintenance Geodatabase hydrography dataset are extracted and reassigned to the Geofabric Surface Cartography Feature Dataset within the Geofabric Surface Cartography Geodatabase. Aushydro V2 includes Geoscience Australia’s national surface hydrology database which is a selection of features from the regional surface hydrology database, at a comparable 1:250,000 mapping density. The regional surface hydrology database is aggregated from multiple jurisdictional sources. The scale of the data ranges from 1:25,000 to 1: 250,000 across the continent (http://www.ga.gov.au/scientific-topics/water/national-surface-water-information). Additional regional features have been added where necessary to ensure important features such as flow paths are included in the Geofabric. As input data is multiscale, and the 1 second DEM approximates a 30m grid cell size, the Geofabric attributes a nominal scale of 1:100,000 across V3 products. 0 450 AHGFHydroLine Feature Class 41078 A barrier of earth and rock, concrete or masonry constructed to form a reservoir for water storage purposes or to raise the water level.
