Burn Dennet and Foyle Network Contribution Scores for Hydrology

Network contribution area scores identify zones of high hydrological connectivity within the Burn Dennet and Foyle catchments in Northern Ireland. The scores were calculated in SAGA GIS using inputs from the CEH Land Cover 2007 map, Met Office average rainfall data, and a 5-meter Digital Terrain Model. The resulting layer is suitable for web map visualization, dashboard analysis, and download in multiple geospatial formats.

Use Cases

• Identifying high-contribution zones for surface water flow based on land cover, rainfall, and topography.
• Visualizing hydrological connectivity patterns in web maps for stakeholder communication.
• Incorporating network contribution scores into environmental dashboards for monitoring.
• Supporting catchment management planning by analyzing areas contributing to river networks.

Strengths

• Derived from established input datasets: CEH Land Cover 2007, Met Office rainfall, and a 5m DTM.
• Available under the permissive OGL-UK-3.0 license, facilitating reuse.
• Accessible in multiple geospatial formats (e.g., GeoPackage, Shapefile, GeoJSON) for various tools.

Limitations

• Core input land cover data is from 2007, which may not reflect current conditions.
• Specific column names, row counts, and spatial resolution are not documented in the provided metadata.
• The 'last updated' date (2026-07-08) is a future date, indicating a potential metadata error.
