Corridors of River Recovery for NSW Hawkesbury Nepean Catchments

A geospatial database identifying corridors for river recovery across freshwater streams in the NSW Hawkesbury Nepean catchments. It was created by Macquarie University researchers in 2022 using the NSW River Styles database accessed in January 2021. The database maps thirteen predefined connections and allows users to run over 80 different scenarios for river management prioritization.

Use Cases

• Prioritizing river rehabilitation projects based on mapped recovery potential classes.
• Identifying upstream-downstream reach connections for building system-wide resilience.
• Seeding and extending recovery from isolated loci connections as described in the workflow.
• Running user-defined scenarios for strategic conservation planning.

Strengths

• Includes thirteen predefined spatial connection types for immediate analysis.
• Workflow allows for running over 80 user-defined scenarios.
• Based on the Open Access NSW River Styles database from DPIE.
• Funded by an Australian Research Council Linkage project with industry partners.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the NSW Hawkesbury Nepean catchments.
