Carlingford and Newry Network Contribution: High Surface Water Flow Areas

Carlingford and Newry Network Contribution data contains geospatial scores identifying areas of high contribution to surface water networks in Northern Ireland. The scores were calculated within SAGA GIS using inputs from the CEH Land Cover 2007 dataset, Met Office average rainfall, and a 5-meter Digital Terrain Model. The 'High contribution' category is defined as areas scoring above one standard deviation from the mean.

Use Cases

• Identifying high-priority areas for flood mitigation based on surface water contribution scores.
• Visualizing potential surface water flow pathways in web maps for environmental dashboards.
• Integrating land cover and rainfall data for hydrological modeling in the Carlingford and Newry region.
• Assessing the impact of land use changes on surface water connectivity using standardized contribution metrics.

Strengths

• Derived from authoritative UK sources including CEH Land Cover and Met Office data.
• Methodology is explicitly described, using a +1 standard deviation threshold to define high contribution areas.
• Available on multiple government data platforms, indicating formal curation and public availability.

Limitations

• Specific column names and data schema are not provided in any source, limiting detailed analysis.
• The underlying land cover data is from 2007, which may not reflect current conditions.
• Row counts and file sizes are not documented, making it difficult to assess the dataset's scale.
