GeoScour - A Geological assessment of the potential for river scour
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 g

Useful for
- Use cases llm-inferred
- Catchment-level screening of river scour risk for bridges and culverts using Tier 1 summaries · Tier 2 catchment inputs for natural flood management and catchment management plan appraisal · Tier 3 geological and sinuosity inputs for reach-scale river scour model setup · Identifying geological factors (mineralogy, strength, density) that affect scour potential at a site
- Audience llm-inferred
- flood consultants · hydrologists · geomorphologists · geotechnical engineers · civils and bridge engineers · infrastructure asset managers · planners
Limitations
- Constraints llm-inferred
- Tier 3 data is licensed, not open · Tier 1 is a high-level overview and is not designed for detailed reach-scale assessment · Tier 2 is limited to smaller catchment areas · Use is at the customer's own risk and NERC gives no warranty on accuracy or suitability · Reproduction and transmission of BGS-derived material requires copyright holder permission
