GeoScour v2 - A geological assessment of the potential for river scour

BGS GeoScour v2 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 v2 includes 18 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 dataset product fills a gap in current scour modelling, with the i

What's in it

Data offered docs-verified: river scour susceptibility (Great Britain) · catchment stability summary (Tier 1) · catchment geological properties and scour susceptibility statistics (Tier 2) · riverine geological properties, river fall, sinuosity and flood accommodation space (Tier 3) · 18 GIS layers
Coverage docs-verified: Great Britain
Resolution docs-verified: Three tiers from catchment scale (Tier 1-2) to local channel/reach scale (Tier 3); no numeric spatial or temporal resolution stated
Update frequency docs-verified: as needed (no fixed schedule)
Formats docs-verified: GIS layers (18 layers; file format not stated)
Access docs-verified: Tiers 1-2 open under Open Government Licence (OGL); Tier 3 licensed, with terms not stated in docs. No API or auth listed.

Useful for

Use cases llm-inferred: Scour susceptibility screening of bridge and culvert crossings for flood risk or FRA work · Catchment-scale screening for catchment management plans and natural flood management using Tier 1-2 data · Geological inputs (mineralogy, strength, density) for reach-scale river scour models using Tier 3 data
Audience llm-inferred: flood consultants · hydrologists · geomorphologists · geotechnical engineers · infrastructure asset managers

Limitations

Constraints docs-verified: Geological factors only; no hydraulic or hydrodynamic factors considered · Tier 3 is licensed rather than OGL · No warranty on accuracy or suitability; use is at the customer's own risk · No numeric spatial resolution stated
