Flood Vulnerability Assessment

Global building-level assessment

Disclaimer: GFVM is a research tool that provides terrain‑based flood vulnerability estimates for informational purposes only. Outputs represent approximate indications of relative flood vulnerability and are not a substitute for professional engineering assessments, official flood maps, regulatory determinations, or local risk surveys. Use of this tool is at your own risk. Nazarbayev University and the authors accept no liability for any decisions, damages, or losses resulting from the use or interpretation of these outputs.

Basic Assessment

Quick vulnerability analysis for a single location

Batch Processing

Upload a CSV file to assess multiple locations simultaneously

Choose the assessment type for batch processing

Required columns: latitude, longitude in decimal degrees (e.g. 29.17, -95.31). Optional: height(meters), basement (should be negative).

About & Methodology

Model description, limitations, and citation

Model Description

The Global Flood Vulnerability Model (GFVM) generates building-level flood vulnerability indices derived from multi-source remote sensing and terrain analysis. Outputs represent modeled estimates subject to data resolution limits, temporal lags, classification uncertainty, and methodological assumptions.

Limitations

GFVM outputs do not replace official government flood hazard maps, site-specific hydrological or hydraulic assessments, insurance determinations, emergency planning instruments, or qualified professional advice. The developers and Nazarbayev University bear no responsibility or liability for property, financial, legal, or safety decisions made based on use of this tool.
