Coastal Deposition Features: Bars
What are bars and how are they created?
A bar is formed where a spit continues to grow across a bay or inlet joining two headlands, creating a lagoon behind it. The lagoon, becomes an area of still water and a salt marsh forms in this low energy zone. Over time the lagoon will become infilled by deposition as either rivers flows in to it depositing material, or as waves break over the top of the Bar depositing coastal material
Named example: Slapton Sands is a bar off of Start Bay, Devon (the lagoon behind Slapton Sands is called Slapton Ley).
