Waterways Centreline

Layer containing line objects delineating hydrological features, representing waterways managed by Melbourne Water (i.e. catchment size is greater than 60 hectares) that have not been significantly modified by human activity. Captured by digitizing a line along the centre of a linear geographic feature. Includes the waterway name, a unique asset identifier, EPMS/asset section number (to link the object to associated drawings) and key attributes to assist with its intended purpose. When used in conjunction with the constructed waterways centreline and waterway connector centreline layers, this layer completes the waterway/hydrology linear network (complete centreline) for Melbourne Water’s non-underground drainage assets. Data set is used to indicate the location and types of natural waterways for asset management and maintenance works, to assess buildover or planning applications, for waterway rehabilitation works and flow management (helping maintain the flow of water and reduce the impacts of floods), ongoing condition monitoring and hydrologic modelling and analysis and to assist with the planning and design, construction of new waterway corridors, stormwater management (WSUD) options.Waterway (Reach) layer created from original FIS 1:50K (Vicmap Hydro) streams data set which included only those waterways within catchments of greater than 60ha. Waterways (Reach) Rectification project undertaken 2001 to 2003 to review and correct the extent of the waterways reach network to ensure a complete data set exists (using the Drainage Metropolis Boundary, 50K data, 1:2500 Drainage Record Plans, Drainage Limits data, orthophotos, as constructed and/or design drawings, contour data and Melway Street Directory). Waterway (Reach) extents defined and attributes populated in GIS and AMIS for all records including assigning nodes and node numbers (for start / end points) and removing any reaches less than 100 metres in length that are predominantly channel assets. Waterways in extended area incorporated in 2005 using Vicmap Hydro data and aerial imagery, then updated in 2009/10 using Lidar survey data (contours). Data is maintained using Lidar survey data (contours) and 60 ha limits.
