tideline
Beach debris boundary
A tideline is the mark left on a shore showing the highest point reached by the tide.
It's often visible as a line of seaweed, shells, and debris deposited by receding water.
The term extends to any boundary or limit: the tideline between his public and private life.
On paper or fabric, a tideline is a watermark stain where moisture has dried, leaving a faint ring.
