<span>Longshore drift is a geographical process that consists of the transportation of sediments (clay, silt, sand and shingle) along a coast at an angle to the shoreline, which is dependent on prevailing wind direction, swash and backwash. This process occurs in the littoral zone, and in or close to the surf zone.</span>

Answer is: repetitive action of swash and backwash transports sediment sideways along the coast.

Longshore drift is a geological process of the transportation of sediments.

Wind squeezes water along the coast and generates a water current which moves parallel to the coast.

Longshore drift plays a large role in the evolution of a shoreline.

There are formulations (Bijker formula, The Van Rijn formula ...) that explain intensity of longshore drift.
