Below, you’ll find a comprehensive, curated table of international and Asia-Pacific flood risk maps and tools. These platforms are designed to help you:
- Check real-time and forecast flood risk at local, national, or global levels
- Explore flood hazard data for any region, including riverine, coastal, and urban flooding
- Access resources in multiple languages, often with open, downloadable data for deeper analysis
- Support safer decisions before, during, and after flood events—whether at home or abroad
Using the Table
- Start with your country or region: Most countries and many major river basins now offer public flood risk viewers or alerting systems.
- Check the tool’s description: Some focus on real-time alerts, others on long-term risk and planning.
- Look for language and scope: Many tools offer English versions or multilingual datasets.
- Link out to the platform: Every entry includes a clickable link to the official resource.
Tip: For local or city-level risk, always check with national meteorological or disaster agencies, as well as regional or municipal governments, for the most precise and actionable updates.
