Authors: Schubert J.E., Luke A., AghaKouchak A., and Sanders B.F.

Content:
(1) GeoTIFF format raster files (.tif) at 1/9th arc second spatial resolution (approximately 3 m) for the hindcast scenario (H-U10) and forecast scenarios (F-U10, F-U20, and F-U40) of Hurricane Hravey.
The raster files represent the maximum accumulated flood depths during a 5 day period (08/26/2017 - 08/30/2017) of Hurricane Harvey induced precipitation and storm surge.
Horizontal datum: Geographic Coordinate System, North American Datum 1983 (NAD83), degrees.
Vertical datum: North American Vertical Datum 1988 (NAVD88), meters.

(2) Esri format Geo-database (.gdb) containing U.S. census block polygons with average flood depth for each scenario (H-U10,F-U10,F-U20, andF-U40).
Average flood depth for each land block was extracted from the 1/9th arc second resolution GeoTIFF rasters.
Also included is the damage classification within FEMA’s 1% special flood hazard area based on property claims, auto claims and census blocks. A value of zero is indicative of no aggregated damage claims, while a value of 1 indicates aggregated damage claims. 
Horizontal datum: Projected Coordinate System, North American Datum 1983, StatePlane Texas South Central, FIPS 4204, Feet.

The spatial extent of the flood hazard layers is approximately 9,000km2, encompassing Harris County, Texas
