Tar River Basin Flood-Inundation Mapping
In cooperation with the North Carolina Division of Emergency Management, Floodplain Mapping Program, the U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in the Tar River basin. These maps depict the approximate area that would be inundated at selected water levels, ranging from approximately top-of-bank to the maximum observed water level. The inundated areas depicted on these maps are approximate, and accuracy of the maps is a function of the accuracy of the topographic data and the hydraulic models on which the maps are based.
Mapped inundation is presented in increments of 1 foot. Maps are referenced to stream stage and to mean sea level relative to North American Vertical Datum of 1988. Maps are presented at two scales: 1:24,000 and 1:12,000. The 1:12,000-scale maps include road names. Sites can be selected from the drop-down menu or by selecting sites from the map of the Tar River basin.
