Victorian Coastal Nearshore Bathymetry with 20m Resolution and 5m Contours

20-meter resolution bathymetry and 5-meter contour intervals for the nearshore Victorian coast, derived from LiDAR and multibeam surveys. The Department of Energy, Environment and Climate Action created this dataset based on information acquired between November 2008 and April 2009. It generally extends to the 20-meter depth contour along the Victorian coastline.

Use Cases

• Model coastal erosion and inundation based on the high-resolution nearshore depth data.
• Plan marine infrastructure projects using the detailed bathymetric contours.
• Analyze seabed morphology and habitat mapping from the LiDAR and multibeam-derived bathymetry.
• Support hydrodynamic and wave modeling for the Victorian coast using the depth information.

Strengths

• Provides a 20-meter resolution digital elevation model for the nearshore zone.
• Includes 5-meter contour intervals derived from the bathymetry for detailed analysis.
• Combines LiDAR-derived bathymetry with multibeam data for Westernport Bay.

Limitations

• Data acquisition occurred between 2008 and 2009; conditions may have changed.
• Column-level documentation is absent; field semantics must be inferred after download.
• The spatial extent is defined as 'generally' to the 20m depth contour, which may be approximate.
