Flood check

The GDV “Hochwasser-Check” is an interactive online flood and heavy rainfall risk assessment tool developed by the German Insurance Association (GDV). The platform allows homeowners, tenants, and property owners in Germany to assess location-specific exposure to river flooding and heavy rainfall by entering an address. It combines public flood hazard maps, meteorological data, and insurance-related risk information to provide comparative local risk assessments, information on past extreme events, and guidance on insurance and property protection measures.

Open tool

What you can do with it

Input

  • Enter a German address to assess location-specific flood and heavy-rainfall exposure
  • Combine public flood hazard maps, meteorological data and insurance-related risk information

Output

  • Reports and decision-support material, including comparative local risk assessment, past-event information, and insurance/property-protection guidance

Use it to

  • Assess a specific address's exposure to river flooding and heavy rainfall
  • Identify adaptation options at property level, informed by insurance and protection guidance
  • Prepare the ground for property-level flood risk and vulnerability assessment

Why is it relevant to climate adaptation

One of the few tools aimed directly at individual property owners rather than authorities or planners, linking hazard information to a concrete decision point — insurance and property protection. It draws on commercial/third-party data alongside public sources, and its underlying data has no systematic update cycle; no nature-based-solution, cost-benefit or just-resilience functionality.

Used in

  • Property-level flood and heavy-rainfall risk assessment for homeowners, tenants and property owners in Germany, developed by the German Insurance Association (GDV)
  • Buildings, business and industry, disaster risk reduction and financial sectors, at national and subnational level
