Lower Lough Erne Network Contribution: Hydrological Risk Areas

Network contribution area scores derived from hydrological modeling within SAGA GIS. The scores are based on inputs from CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model. The 'High Network Contribution' category boundary was determined by selecting areas scoring above +1 standard deviation of the score distribution.

Use Cases

• Identifying high-risk areas for surface water runoff and connectivity based on integrated land cover, rainfall, and terrain data.
• Visualizing potential hydrological contribution zones for dashboard-based environmental monitoring.
• Informing land-use planning by highlighting areas with a high contribution to the river network.

Strengths

• Derived from authoritative UK sources: CEH Land Cover 2007 and Met Office rainfall data.
• Modeled using a standard 5-meter Digital Terrain Model for detailed terrain analysis.
• Available on multiple government data platforms, indicating official use and validation.

Limitations

• The core land cover input data is from 2007, which may not reflect current conditions.
• Specific column names and data structure are not documented in the provided metadata.
• Conflicting 'last updated' dates (2026-07-08 vs 2026-06-18) create uncertainty about the most recent version.
