Summary

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over an 8-day period in Louisiana in August and September 2017. Following the storm event, U.S. Geological Survey (USGS) hydrographers recovered and documented 2,123 high-water marks in Texas, noting location and height of the water above land surface. Many of these high-water marks were used to create flood-inundation maps for selected communities [...]

Purpose

Flood documentation maps were created using GIS to show the extent of inundation along impacted river reaches in Texas following the August and September, 2017 Hurricane Harvey flood event. Flood-inundation maps are intended to estimate the areal extent and depth of flooding that correspond to the HWMs identified and surveyed by USGS hydrographers following the flood event. The mapped area boundary, flood inundation extents, and depth rasters were created to support the development of flood inundation maps for the Federal Emergency Management Agency's (FEMA) response and recovery operations following the August and September, 2017 flood event in Texas.
