Burn Dennet and Foyle Network Contribution: High Surface Water Connectivity Areas

Northern Ireland's Burn Dennet and Foyle catchments are analyzed for surface water connectivity. This geospatial dataset identifies high network contribution areas derived from land cover, rainfall, and terrain models. It is suitable for web map visualization, dashboard analysis, and download for further GIS processing.

Use Cases

• Identifying high-risk flood zones based on hydrological connectivity scores.
• Prioritizing land management interventions in areas contributing significantly to surface water flow.
• Visualizing water network contributions in web-based mapping dashboards.
• Integrating hydrological connectivity data with other environmental datasets for catchment modeling.

Strengths

• Derived from established inputs: CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model.
• Cross-platform availability indicates established use and validation.
• Methodologically defined threshold: High contribution boundary set at +1 standard deviation of the score distribution.

Limitations

• Specific column names and data structure are not documented across any source.
• The underlying land cover data is from 2007, which may not reflect current conditions.
• No row count, file size, or sample data is provided to assess dataset scale.
