Inundation depth in meters for coastal and riverine floods
Version 2 (updated October 20, 2020)This webpage provides download links for the Aqueduct Floods Hazard Maps for coastal and riverine flooding. This is the same flood hazard data that is available for exploration within the Aqueduct Floods tool.
Files are distributed as single-band 32-bit float Geotiffs with pixels corresponding the inundation depth in meters for a specific flood return period.
One file is available for each unique parameterization and there are many parameters. Users should consult the Technical Note for information about the methodology and parameters. Common to both the coastal and riverine flood modeling are:
Coastal and riverine flood models are each further parameterized as described below. A data dictionary is available to assist with understanding filename conventions: _Aqueduct_Floods_Data_Dictionary.xlsx
2020-10-20. 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 the Aqueduct Floods tool but was missing from the downloadable files 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 Technical Note.
The update only impacts the riverine maps. If you downloaded hazard maps prior to October 20, 2020, we recommend you redownload the data.
In addition to the parameters described above the model results have two configurations for the inclusion of land subsidence.
