Glens Rathlin Network Contribution: High Surface Water Flow Areas in Northern Ireland

Network contribution area scores were exported from the SciMAP application outputs within SAGA GIS. The scores were based on inputs from CEH Land cover 2007, Met Office average rainfall and a 5 meter Digital Terrain Model. This geospatial layer identifies high-contribution areas for surface water flow, defined as areas scoring above +1 standard deviation of the distribution.

Use Cases

• Identifying high-risk areas for surface runoff and potential flooding based on land cover, rainfall, and topography.
• Visualizing water network connectivity for environmental dashboards and web maps.
• Informing land-use planning decisions by highlighting zones with high hydrological contribution.
• Supporting academic research in catchment hydrology and geomorphological processes.

Strengths

• Derived from established, authoritative input sources: CEH Land Cover 2007, Met Office rainfall data, and a 5m DTM.
• Available under the permissive OGL-UK-3.0 license, facilitating reuse and analysis.
• Cross-platform presence on UK and EU open data portals indicates recognized utility and stability.

Limitations

• Specific column names and data schema are not provided, limiting understanding of the exact attributes.
• The land cover input data is from 2007, which may not reflect current conditions.
• Dataset size, row count, and author information are consistently missing across all sources.
