east coast florida sand depths.

anyone know the general depth of sand above hardpan along central east coast and south central east coast beaches?
is there a good way to track this other than judging by landmarks or found items?
I realize everything is shifting and moving but if noaa or someone else tracks this I would like to know. is there a site that tracks currents?

some areas/types of beaches would be more prone to erosion, some prone to adding sand , some would change more often than others, etc:

thanks, I have a few links like that but have not been able to find any that describe sand depths on and near the beach.
