View the Risk of Flooding with Google Maps

Flood Map allows you to view the risk of flooding at any location in the world.

Using flood map you can set a water elevation height for any location and view the likely effects on a Google Map. Areas that are likely to be flooded are displayed on the map with a blue overlay.

It is also possible to right-click on any location and view the elevation level at that point. If you want to share a Flood Map search you can cut and paste a link to the current map view.

Um, no. Flood risk is rather more complicated than that.

Yes, great idea, but some fundamentals are missing:

- A 90m grid of elevation data doesn't allow you to model flood, period;
- Water doesn't rise uniformly, it rises in a complicated fashion based on water flow, width of the river, bends in the river, local topography, soil saturation etc...

E.g. the Jan 2011 Brisbane floods recorded the following river gauge heights, all at the same time, going up the river: 2.5m, 4.5m, 9m, 18m.

Could you guys raise this flood map from 800 meters to 2000 meters so that I can use this flood map to keep track of the global flood in Baxter's Book Flood which is a book that is a prequel to the movie Waterworld. I would really like to use this to see what would be the last piece of dry land left.

That would be great. I happen to be reading Baxter's Ark at the moment which is also about the world being completely submerged by rising sea levels.
