Vulnerability of Objects to Flooding After Dike Breach in the Netherlands (2019)

A Dutch geospatial dataset from 2019 assessing the vulnerability of buildings and objects to flooding from primary and regional water system breaches. The dataset classifies vulnerability based on the calculated water depth against a building's facade, derived from comparing maximum flood water depth maps with floor levels from elevation data (AHN2/AHN3). It was produced by the Ministry of the Interior and Kingdom Relations and is licensed under CC-PDM-1.0.

Use Cases

• Prioritizing flood mitigation investments based on object vulnerability classifications.
• Modeling potential damage scenarios from dike breaches using water depth thresholds.
• Validating flood risk models by comparing predicted water depths against building floor levels.
• Assessing regional flood preparedness by mapping the spatial distribution of vulnerable objects.

Strengths

• Provides a specific vulnerability classification system based on water depth thresholds (0-0.2m, 0.2-0.5m, 0.5-2.0m, >2.0m).
• Methodology is described, involving the integration of flood maps (primary and regional) with elevation data (AHN2 and AHN3).
• Includes a defined process for linking objects to buildings within a 50-meter search radius.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
• Column-level documentation is absent; field semantics must be inferred after download.
