Ballinderry Network Contribution: High Surface Flow Areas

Northern Ireland's Ballinderry River catchment area is analyzed for hydrological network contribution. The dataset identifies high-contribution zones based on land cover, rainfall, and terrain inputs from 2007. It is a processed geospatial layer derived from SciMAP application outputs within SAGA GIS.

Use Cases

• Identifying high-contribution zones for surface flow based on land cover and rainfall data.
• Visualizing hydrological network influence areas for web-based dashboards.
• Supporting catchment management decisions using standardized deviation analysis of contribution scores.

Strengths

• Derived from established inputs: CEH Land Cover 2007, Met Office rainfall, and a 5-meter Digital Terrain Model.
• Processed using a defined scientific method: High contribution boundary set at +1 standard deviation of score distribution.
• Available on multiple government open data platforms, indicating official provenance and review.

Limitations

• Specific column names and data structure are not documented in the provided metadata.
• Core input data (land cover, rainfall) is from 2007, which may not reflect current conditions.
• Exact spatial resolution and dataset size (row count, file size) are unknown.
