WMS 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. GeoScour includes 11 GIS layers, providing information on the natural characteristics and properties of catchment and riverine environments for the assessment of river scour in Great Britain. The data product fills a gap in current scour modelling, with the input of geological properties. It provides an improved toolkit to more easily assess and raise the profile of scour risk, now and in the future, to help infrastructure providers and funders prioritise resources, identify remedial works to preclude costly and prevent disruptive failures. The data product has broad applications through its adaptation to suit multiple types of asset likely to be affected by fluvial erosion. The GeoScour Data Product is designed to be used by multiple stakeholders with differing needs and therefore, can be interrogated at a number of levels. Tier 1 data provides a summary overview of the catchment characteristics, typical response type, and evolution. It can be used as a high-level overview for incorporation into catchment management plans, national reviews and catchment comparisons. Tier 2 data are available as smaller catchment areas and focusses on providing data for more detailed catchment management, natural flood management and similar uses. It analyses geological properties such as flood accommodation space, catchment run-off potential, and geomorphology types, as well as additional summary statistics of key environmental parameters such as protected sites and urban coverage. Tier 3 data provide the detailed riverine information that is designed to be incorporated into more complex river scour models. It provides the baseline geological context for river scour development and processes and identifies important factors that should be considered in any scour model. Factors such as material mineralogy, strength and density are key properties that can influence a river’s ability to scour. In addition, an assessment of river fall, sinuosity and flood accommodation space is also provided. This data is of use to all users assessing the propensity for river scour for any given reach of a river across Great Britain. Tier 1 and 2 data are available with an OGL, Tier 3 data is licenced.

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.

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.

This layer provides statistics on specific geological properties per river reach. The geological properties include superficial deposits vs bedrock, rocks strength, density and mineralogy. The statistics correspond to the percentage length of river reach for each different geological property encountered.
