Larne Lough Network Contribution: High Surface Water Flow Areas

Network contribution area scores were exported from the SciMAP application outputs within SAGA GIS. The scores were based on inputs from CEH Land cover 2007, Met Office average rainfall and a 5 meter DTM. The High contribution category boundary was determined by selecting +1 standard deviation of the distribution of the scores.

Use Cases

• Identifying high-risk areas for surface runoff based on land cover and rainfall inputs.
• Visualizing potential water network contribution zones for environmental dashboards.
• Supporting catchment management planning using derived GIS analysis outputs.

Strengths

• Derived from specific, documented input sources: CEH Land Cover 2007, Met Office rainfall, and a 5m DTM.
• Available under an open license (OGL-UK-3.0), facilitating reuse.
• Cross-platform presence on uk_data and eu_open_data indicates established use.

Limitations

• Column names and data structure are unknown, limiting immediate analytical use.
• Metadata for size, row count, and author is missing from all sources.
• The primary input land cover data is from 2007, which may not reflect current conditions.
