Natural hazards maps
Flood
Prepare for one of the world’s most expensive hazards with our landmark worldwide flood map.
Climate change, globalization and urbanization are driving factors behind flood events and their consequences. As a company dedicated to helping commercial and industrial property clients manage their risk and ensure operating resilience, 91°µÍø has conducted extensive research—building on the data and experience of noted governmental and research organizations—to develop a Worldwide Flood Map that identifies areas exposed to moderate- or high-hazard flooding.
In addition to historical flood data, the Worldwide Flood Map is derived from physically based hydrology and hydraulic scientific data, which accounts for variable external factors such as rainfall, evaporation, snowmelt and terrain. The Worldwide Flood Map is particularly valuable in parts of the world where local or regional flood maps are inconsistent or unavailable. The Worldwide Flood Map currently displays high (100-year) and moderate (500-year) hazard flood zones via a 90 x 90-meter grid.
Our Worldwide Flood Map lets you see the flood exposure for any location in the world.
