longshore drift

A ridge of sand that runs parallel to the shore is called a sandbar. Sandbars are typically submerged or partially exposed at high tide and can be an important habitat for marine life.
Sand gets transported along a beach primarily through longshore drift, where waves approach the shore at an angle and carry sediment parallel to the coastline. Additionally, tides and currents can also contribute to the movement of sand along a beach.

long-shore drift
Longshore currents transport sediment along the coastline parallel to the shore. These currents are driven by the waves hitting the coast at an angle, causing sediment to move in a zig-zag pattern along the shoreline.

sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
Long-shore drift occurs in two ways: the wave driven movement of sand along the exposed beach and the current-driven movement of sand in the surf zone just offshore.
Shoreline current refers to the movement of water parallel to the shore, influenced mainly by tides and waves. Longshore current, on the other hand, is a specific type of shoreline current that moves parallel to the shore within the surf zone, transporting sediment along the coast.
