Flood Depth

Flood exposure from terrain alone: map flood extent, depth, probability and exposed assets anywhere on Earth.

What it does

Search a town, river or region, draw an area, or pick an example, and see how water would spread across the terrain.

Extent and depth

Where water reaches and how deep it gets, mapped across the area.

Probability

How likely each place is to flood, not just a single yes or no.

Exposed assets

What sits inside the flooded area, highlighted on the map.

Anywhere on Earth

Runs in the browser, with no local GIS software or data downloads.

How it works

Flood Depth models water from the shape of the land, so it works even where no detailed flood study exists.
