BGS GeoScour provides river scour susceptibility information for Great Britain using a three-tiered data provision allowing increasing levels of understanding at different resolutions from catchment to local (channel/reach) scales.
The Catchment_Morphology layer is part of a suite of 12 GIS layers, organised into three different levels (Tiers 1, 2 and 3) and focussing on the natural characteristics and properties of catchment and riverine environments. This layer is part of the Tier 2 level, which focusses on the small catchment areas. Tier 2 contains five other layers: Catchment_Geological_Runoff_Potential,
Catchment_Land_Cover,
Catchment_Flood_Accomodation,
Catchment_Urban_Coverage, and Catchment_Designated_Sites.
The catchment morphology layer was developed by analysing the dominant morphology type per catchment area and attributed into one of 5 categories: uplands, lowlands, hill & vale, mountain, or coast & estuarine; and 5 associated descriptions. A combination of the EA's Scottish Catchments, England & Wales Catchments, and BGS Quaternary Domain Descriptors reclassified. |
