Study: East Coast flooding increasing

Annapolis, 2003 (Reuters)

Reuters, the wire service, is in the midst of a big data project looking at flooding on the East Coast. Today they published their first bit on it, showing a huge increase since the 1970s in the average number of days major East Coast cities spend partially under water each year.

Leading the way? Annapolis, Maryland.

The capitol city averages 34 floods a year now, Reuters says.

The data comes from the hourly tide gauge readings. The wire service grabbed 25 million of them and then compared them to flood threshold data from the National Oceanic and Atmospheric Administration.
