Natural Waterway Centerlines for Melbourne Water Management

Aggregating line objects delineating natural waterways managed by Melbourne Water, specifically those within catchments larger than 60 hectares. It includes attributes such as waterway name, unique asset identifier, and EPMS/asset section number for linking to associated drawings. The data is used for asset management, planning applications, hydrologic modeling, and flood impact analysis.

Use Cases

• Link waterway assets to associated engineering drawings using the EPMS/asset section number for maintenance planning.
• Analyze the linear waterway network using the unique asset identifier for connectivity and flow management studies.
• Assess planning applications by referencing waterway name and location data against catchment size criteria.
• Support hydrologic modeling by utilizing the centerline geometry and associated attributes for natural waterway segments.

Strengths

• Data is maintained using Lidar survey data (contours) for accuracy.
• Waterway extents were defined and reviewed in a rectification project from 2001 to 2003.
• Includes waterways within catchments greater than 60 hectares, providing a specific management threshold.

Limitations

• The dataset excludes waterways significantly modified by human activity and those less than 100 meters in length.
• Accuracy and completeness are not guaranteed, as stated by the data provider.
• Specific row count, column count, and sample data are unavailable for assessing scale and structure.
