1 Madison Phillips Berdugo Geo 07 February 2024 4.2.2 Lab: Coastal Erosion Case Study After learning about “El C”, I decided to do some more research to find the best conclusion for the citizens on this barrier island. In the sketch below it shows what a barrier island would look like and how it can be affected by sea level rise. After completing this sketch it is clear to see that the people on “El C” are really affected by coastal erosion. Coastal erosion is the natural process that occurs when sea level rises, strong waves, tides, and currents hit the shore. After this process the sediments or rocks are washed up and deposited elsewhere,which causes a change in the island shape. For this reason I believe that if a structure was made to stop the erosion and trap the moving sediments, the civilians of “El C” should no longer be in as much danger as before.

2 I believe this solution could work because in Louisana, the land was starting to get smaller and smaller due to coastal erosion. To help stop this erosion from happening, they started to plant vegetation near the wetlands to help keeps all the washed up sediments in the same place they were originally at. This has worked really well for Louisiana’s coastal regions and I think it could work even better in the future at “El C” with more and more time and dedication put into it. I think building a structure is the best solution because it will be easier to maintain rather than planting vegetation like Louisana did. I think planting vegetation is another good idea but in the long run, I believe that it would just to be too much work to handle. Although if there was a structure would stay up in its place and wouldn't need as much maintenance as other things. With this structure it would basically just act as a wall with tiny drainage towards the bottom so the water leaves, but the sediments stay. Every so often the wall will have to get moved back a little bit, just so the island can keep on growing. In 10 years I think the barrier island “El C” would be thriving. I believe the island will start to grow back and possibly even grow larger than it was before. Within 10 years I think all

3 the upsets and hiccups with the structure will be gone and the island will not have to worry about the dangers anymore.
