Aqueduct Floods Hazard Maps

Inundation depth in meters for coastal and riverine floods

Version 2 (updated October 20, 2020)

The downloadable hazard maps were updated on October 20, 2020 to fix a bias-correction error in the data. This correction was made prior to the release of Aqueduct Floods but was missing from the downloadable and tool hazard maps. It does not impact any results created by the Risk Analysis or Cost-Benefit Analysis. To read more about the update, see Appendix 1.1 in the Techincal Note. Please note, the downloadable hazard maps (original and updated) show inundation depth in meters.

The update only impacts the riverine maps. If you downloaded hazard maps prior to October 20, 2020, we recommend you redownload the data.
