Assessing Your Flood Resilience
Flood is one of the most devastating and costly of all natural disasters. There are three primary factors behind the increased frequency and severity of flood loss: climate change, globalization and urbanization. A fourth factor may be attributed to the fact that, in many parts of the world, flood information can be unreliable, inconsistent or outdated—or simply doesn’t exist. As resilient businesses expand globally, they need a trusted resource that can help identify potential flood exposures on every continent.

Our Global Flood Map breaks new ground. It’s a physically based map that provides a worldwide view of moderate- and high-hazard flood zones across the globe. Unlike maps based solely on historical flood data, our innovative Global Flood Map is built using hydrology and hydraulic science, and considers, among other factors, essential information like rainfall, evaporation, snowmelt and terrain.

About Global Flood Map

Why did FM Global create their own Global Flood Map?

“The Global Flood Map was created to help our clients understand their flood exposures worldwide,” notes Dr. Lorenzo Begnudelli. “It charts areas of the globe where flood data is lacking or insufficient.”

How does the Global Flood Map work?

“The Global Flood Map identifies potential moderate to high flood hazards,” says Dr. Yasir Kaheil. “Commonly, these are known as 100- and 500-year flood zones.”

What makes the Global Flood Map revolutionary?

“The Global Flood Map is physically based,” explains Dr. Yasir Kaheil. “In addition to hydrological cycles, it accounts for ground elevations and surface texture.”

Why does the map show blocks when zoomed in?

"The Global Flood Map displays topographical data in 90 x 90 meter blocks,” explains Dr. Yasir Kaheil. “We intentionally left the original display as is, because the accuracy of the flood exposure is more precise.”

Why doesn't the Global Flood Map include levees or dams?

“We chose not to include levees or other water management structures at this time,” states Dr. Lorenzo Begnudelli. “It’s a complex task and the information isn’t universally available—yet.”
