DDT 70: Clay Shrink-Swell Hazard Zones in Haute-Saône, France (2009)

Hazard zones for clay soil dewatering and swelling phenomena in the Haute-Saône department of France, mapped in 2009. The dataset was produced by the Bureau de Recherches Géologiques et Minières (BRGM) and includes shapefiles delineating risk areas. It was last updated on the platform in September 2019.

Use Cases

• Modeling soil deformation risk for infrastructure projects based on the described clay dewatering and swelling phenomena.
• Integrating geological hazard zones into regional planning maps based on the provided shapefile format.
• Assessing the impact of drought on soil stability in the Haute-Saône area based on the described risk mechanism.

Strengths

• Produced by the authoritative geological survey organization BRGM.
• Includes geospatial data in shapefile format for direct GIS analysis.
• Focuses on a specific, documented geological phenomenon (clay shrink-swell).

Limitations

• Data is from a single year (2009); conditions may have changed.
• Row count and column-level documentation are unknown, requiring inspection after download.
• The description metadata is limited, lacking details on specific attributes within the shapefiles.
