Local Flood Probability Maps for the Netherlands (2020)

A set of map images showing the probability of flooding with water depths exceeding 20 cm in the Netherlands. The data was developed by the DPRA and is based on scenarios of primary flood defense breaches from the National Flood Data Database. The dataset is provided by the Dutch Ministry of the Interior and Kingdom Relations under a CC-PDM-1.0 license.

Use Cases

• Assessing localized flood risk for land-use planning based on the probability of water depth exceeding 20 cm.
• Prioritizing flood defense investments by analyzing the combined probability from multiple breach scenarios.
• Modeling potential flood consequences by integrating this probability map with other geospatial data.

Strengths

• Focuses on flood probability, which provides a more nuanced risk assessment than maximum water depth alone.
• Based on official national flood scenarios from the National Flood Data Database.
• Explicitly models the increased probability at locations affected by multiple breach scenarios.

Limitations

• Data format is PNG images, which limits direct computational analysis without conversion or digitization.
• Some archived flood scenarios could not be incorporated, leading to potential gaps in coverage.
• Row count, file size, and last update date are unknown, limiting suitability assessment.
