Paper Summary

The Keta Sand Spit in Ghana has changed over thousands of years due to river mouth shifts. The current spit formed around 2500 years ago and is slowly moving eastward. Coastal erosion behind the spit is mainly caused by natural factors like wave currents, not by reduced sediment from the Volta River dam.
