Answer:
They Absorb Water
Explanation:
Salt Marshes have a lot of use cases. They protect the coasts from erosion as well as maintain the quality of the water by filtering the runoff. Salt Marshes also reduce inland flooding be absorbing rain water and keeping it from the inland. This is why Salt Marshes such as the one in Cape Hatteras are kept instead of being removed for city projects.
