This shapefile delineates historic water bodies including wetlands, the old Yarra River and Moonee Ponds Creek alignments and lakes (presumably seasonal and generally estuarine). The polygons are digitised from the 1855 map "Melbourne and its Suburbs" compiled by James Kearney, draughtsman ; engraved by David Tulloch and James D. Brown. http://handle.slv.vic.gov.au/10381/89107

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. Please refer to metadata for each record in dataset for specific source / accuracy information.

This data contains points representing drain and waterway outlet locations, associated with a natural waterway or channel centreline, within the Greater Melbourne region. This region includes the Port Phillip Bay and Western Port coastlines. Points are captured to show the indicative location of the endpoint for a waterway or channel as geographic coordinates. The data table includes minimal attributes to assist in identifying the feature.

This dataset describes in stream turbidity for watersheds included in a paired watershed study including a forested reference watershed and three urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA. Turbidity was monitoring from June 2010 to December 2010, March 2011 to December 2011 and June 2012 to October 2012 in For-MD and Cent-MD, and only the 2011-2012 time period in Dist-MD. Mean turbidity in NTU was recorded at 5-minute intervals during the 2010-2012 monitoring seasons with a Forest Technology Systems, Digital Turbidity Sensor DTS-12. Mean turbidity was computed from 100 instantaneous recordings during the time interval. Sensor accuracy is ±2% of reading (0-399 NTU) and ±4% of reading (400-1,600 NTU), with a turbidity range of 0 to 1,600 NTU.

Catchment area for each Melbourne Water drain. Captured using available contours and drainage network information. This layer has two intended purposes:,

Polygons representing natural waterway or channel structure locations (such as sediment ponds, litter traps, weirs, spillways, drop structures) and associated details. Includes description, asset section (for As Constructed drawings) and key attributes. This layer is intended to help identify the location of Melbourne Water's drainage assets for asset management and maintenance purposes. 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.
