Flood Hazard Isocote Lines for the TRI Loir Region at 1.40m Water Height

A spatial dataset of isocote lines representing water level altitudes during flooding, produced for the Loir Territory at Risk of Flooding (TRI). The dataset was created by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated on March 28, 2019, to support flood risk management plans mandated by the European Floods Directive (2007/60/EC). Its primary objective is to provide quantitative evidence for assessing territorial vulnerability across high, medium, and low flood probability levels.

Use Cases

• Generate flood surface and flood risk maps based on the isocote line data.
• Assess territorial vulnerability to flooding for high, medium, and low probability scenarios as described.
• Support the development of Flood Risk Management Plans (WRMs) required by EU Directive 2007/60/EC.
• Homogenize and objectify knowledge of flood exposure for regional planning purposes.

Strengths

• Produced by a recognized geological and mining research organization (BRGM).
• Explicitly linked to a specific European regulatory framework (Directive 2007/60/EC).
• Designed for mapping at an appropriate scale for flood hazard and risk assessment.

Limitations

• Last updated 2019-03-28 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
