ELI5: What happens to all the sand on the beach(es) after a hurricane/storm surge comes through?

Is all the sand gone?
gpt
It gets dragged out by the water into deeper water.  It doesn't disappear completely (that would be magic) but it is no longer on the shoreline.  With effort, sand can be dredged back up from the deeper water and re-deposited on the beach, but this takes lots of time, money, and causes environmental damage.
