All Wales Hydrological Analysis Catchments
This layer was created to point to rasters used in NRW hydrological analysis tools. They are based upon the flow direction models which were created by the Environment Agency Detailed River Network which subsequently passed to NRW. The All Wales Hydrological Analysis Catchments is generated for each area above a threshold area from the following related datasets: NRW_DS123368 NRW_DS123369 NRW_DS123370 NRW_DS123371

Created as a precursor to the Ordnance Survey Mastermap Water Network. There is a lot of subjectivity in terms to the thresholds used to generate these by-products from the flow direction raster.. It depends on intended use, spatial extent and scale. Changing these variables will alter the number and size of the resulting streams and catchments
