Created using karst information for Rockingham Catchment Region in the West of Ireland. The catchment for each swallow hole was delineated and distance from each swallow hole was calculated within the catchment. These were assigned the appropriate value according to COP methodology. The slope and vegetation types within and outside that catchments were also assigned appropriate values.
Data sources were GSI National Karst database including sinking stream buffer, Digital Terrain Model at 10 m x 10 m resolution (EPA / GSI) and CORINE land cover data. Reclassified distances to swallow holes and sinking streams for Irish karst pilot and Irish situation. Buffering of same with new buffer classifications. The DTM was then created into a slope raster file and assigned appropriate values. Vegetation was classified based on forestry or grassland. It was created using ERSI ArcMap 10.5 and QGIS as a shapefile and converted into .tiff
