2010 Index of Stream Condition: Streambed Width Summary Statistics

The ISC_STREAMBED_WIDTH_S table provides statistical summaries for the Streambed Width metric at 100-meter river sections. The Department of Environment and Primary Industries developed this data using remote sensing from 15cm aerial photography and multi-pulse LiDAR collected during a state-wide mapping project from 2010 to 2013. It is part of a broader effort to assess the Physical Form and Riparian Vegetation components of river health in Victoria.

Use Cases

• Modeling river channel geometry based on streambed width statistics
• Assessing changes in physical stream condition over time based on remote-sensing-derived metrics
• Correlating riparian vegetation health with channel form metrics
• Validating hydrological models with high-resolution topographic data

Strengths

• Derived from high-resolution source data including 15cm aerial photography and four-return LiDAR
• Part of a state-wide mapping project conducted over a 3-year period (2010-2013)
• Data is structured as a combination of mapped vector/raster data and tabular summary statistics

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The dataset focuses only on Physical Form and Riparian Vegetation metrics; other ISC metrics were derived from other sources
