Upper Bann Network Contribution: High Runoff Risk Areas

Derived from 2007 land cover, rainfall, and terrain data, this geospatial layer identifies areas with high potential for contributing surface water flow to the river network in Northern Ireland. It was created by analyzing CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model within the SciMAP application in SAGA GIS. The 'High Network Contribution' category is defined as areas scoring above one standard deviation from the mean contribution score.

Use Cases

• Flood risk modeling based on high-contribution area boundaries.
• Catchment management planning using identified surface water connectivity.
• Dashboard visualization of hydrological contribution zones for stakeholder communication.
• Land use impact assessment on surface runoff using the 2007 land cover input.

Strengths

• Based on established input datasets: CEH Land Cover 2007, Met Office rainfall, and a 5m DTM.
• Methodologically transparent, derived using the SciMAP application within SAGA GIS.
• Available under the permissive OGL-UK-3.0 license for reuse.

Limitations

• Core input land cover data is from 2007, which may not reflect current conditions.
• Specific column names and data structure are not documented in the provided metadata.
• The exact spatial resolution and vector/raster format are not specified.
