3. Conclusion
Sentinel-1 data are available on Sept. 14th, 15th, 17th, 18th and
The best coverage was on 19th
Data on 14th and 15th only covers coastal area and the results are not shown in these slides
Data on 17th only covered the west marginal of the flood thus did not show much flood
Large inundation are detected along the Great Pee Dee River (both 18th and 19th), Cape Fear River, Black River, Neuse River and Coastal Area in NC
Flooding was centralized in NC and northeast of SC and was detected in VA as well
In Great Pee Dee River, inundation on 18th is more severe in upstream than on 19th.
