Description: BGS GeoScour provides a river scour susceptibility model 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_Stability layer is part of a suite of 12 GIS layers, organised into three different levels (Tiers 1, 2 and 3), focussing on the natural characteristics and properties of catchment and riverine environments. This layer belongs to Tier 1, which is based on the large scale water management plan catchment areas across Great Britain. Tier 1 catchment stability data layer was developed as a high-level summary by identifying the glacial limits and quaternary history, attributing typical characteristic behaviours and management considerations using expert elicitation, quaternary domains data, and glacial extents.
Value: Variable run-off potential due to the mixed nature of the deposits within the geological formation e.g. interbedded layers with differing properties Label: Variable run-off potential due to the mixed nature of the deposits within the geological formation e.g. interbedded layers with differing properties Description: N/A Symbol:

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.
