What is the process that builds up the land in tybee island?

The process that builds up the land in Tybee Island primarily includes sediment deposition from rivers, tides, and waves. As the natural forces bring sediment to the island, it accumulates, contributing to the growth and maintenance of the landmass over time. Additionally, vegetation such as marsh grasses and mangroves can also aid in trapping sediment and building up the land.
