Larne Lough Network Contribution: High Surface Flow Areas

Larne Lough Network Contribution data provides geospatial scores identifying areas contributing high surface water flow into the river network of Northern Ireland. The scores were calculated within SAGA GIS using inputs from CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model. The 'High contribution' category is defined as areas scoring above +1 standard deviation from the mean.

Use Cases

• Identifying high-priority areas for surface water runoff management based on land cover and rainfall.
• Visualizing critical contributing zones for catchment health dashboards.
• Supporting flood risk analysis by mapping areas with high potential for network contribution.
• Informing land-use planning by correlating high contribution scores with specific land cover types from 2007.

Strengths

• Derived from authoritative input sources: CEH Land Cover 2007, Met Office rainfall data, and a 5m DTM.
• Clear, statistically defined classification using +1 standard deviation threshold.
• Available under the permissive OGL-UK-3.0 license for reuse.
• Cross-platform presence on uk_data and eu_open_data indicates established utility.

Limitations

• Specific column names and data schema are not provided in any source, limiting precise understanding of attributes.
• Core land cover input data is from 2007, which may not reflect current conditions.
• No row count, file size, or author information is available across any platform.
