GIS5050: Module 4 - Coastal Flooding

In this storm surge analysis lab, A key learning outcome was understanding how elevation data impacts flood modeling when comparing LiDAR DEMs to USGS DEMs. In this lab I learned to model flooding using raster analysis to identify areas suceptable to a 1-meter storm surge. I used tools including Raster Calculator, Region Group, and Extract by Attributes, to isolate connected flood zones. The lab required using Select by Location and Field Calculator to identify buildings affected by flooding. Using Symbology and Map Layout tools, I communicated the high risk zones, and the importance of identifying flood zones.
