500-Year Flooding in Five Cities/Counties

Water and Watersheds

Edward Hessler


Washington Post reporters Leslie Shapiro, Armand Emamdjomeh and Ted Mellnick wondered what 500-year flooding could look like around five cities/counties. This was the extreme weather event experienced in Houston, TX.

These are Harris County, TX, Miami-Dade County, FL, New Orleans, LA, Tampa Bay, FL and New York City.

The result of their work includes a graph, graphics and informative text.
And yesterday, Jason Somenow of the Washington Post's Capitol Weather Gang reported that "a new analysis from the University of Wisconsin's Space Science and Engineering Center has determined that Harvey is a 1-in-1000 year flood event." The essay includes some graphics and a short video on why Harvey was so darn powerful. "Unprecedented in scale."
