Sandbars and Longshore Bars
This bar forms (sometimes seaward of a trough) where the waves are breaking, because the breaking waves set up a shoreward current with a compensating counter-current along the bottom. Also known as a trough bar. Sand carried by the offshore moving bottom current is deposited where the current reaches the wave break. Other longshore bars may lie further offshore, representing the break point of even larger waves, or the break point at low tide.

Famous quotes containing the word bars:
“The last public hanging in the State took place in 1835 on Prince Hill.... On the fatal day, the victim, a man named Watkins, peering through the iron bars of his cell, and seeing the townfolk scurrying to the place of execution, is said to have remarked, ‘Why is everyone running? Nothing can happen until I get there.’”
—Administration for the State of Con, U.S. public relief program (1935-1943)
