Six Mile Water Network Contribution: High Surface Flow Areas in Northern Ireland

Northern Ireland's Six Mile Water network contribution area scores identify zones with high potential for surface water flow into the river network. The dataset was generated in SAGA GIS using SciMAP, based on inputs from the CEH Land Cover 2007 map, Met Office average rainfall, and a 5-meter Digital Terrain Model. The 'High contribution' category boundary is defined as areas scoring above +1 standard deviation from the mean of the calculated scores.

Use Cases

• Mapping high-risk runoff zones based on integrated land cover, rainfall, and topography scores.
• Incorporating into hydrological dashboards for visual analysis of contribution areas.
• Supporting watershed management decisions by identifying key surface flow contributors.
• Visualizing potential surface water connectivity in web-based maps for public communication.

Strengths

• Derived from authoritative input sources: CEH Land Cover 2007, Met Office rainfall, and a 5m DTM.
• Available under the permissive OGL-UK-3.0 license, facilitating reuse.
• Cross-platform presence on uk_data and eu_open_data signals established utility and availability.

Limitations

• Column names and data schema are unknown, hindering precise technical understanding.
• Metadata on row count, file size, and author is consistently missing across all sources.
• The underlying land cover data is from 2007, which may not reflect current conditions.
