Beach material builds up on the downdrift side, where littoral drift is predominantly in one direction, creating a wider and a more plentiful beach, therefore enhancing the protection for the coast because the sand material filters and absorbs the wave energy.

The term has not been extensively researched; specific criteria have not been developed to distinguish " feeder bluffs " from other types of bluffs; and quantities and rates of sediment supply to beaches and the littoral drift are unspecified and unknown.

At that time, it stood only 500 feet ( 150 m ) from the tip of Sandy Hook; however, today, due to growth caused by littoral drift, it is almost one and a half miles ( 2.4 km ) inland from the tip.

Also the canal mouth needed constant dredging due to the littoral drift in both directions on an open, sandy coast, due to winds blowing alternately from opposite quarters, sand accumulates in the sheltered angles outside the harbour between each converging breakwater and the shore.

Thus theoretical studies, laboratory experiments, numerical and hydraulic modelling seek to answer questions pertaining to littoral drift and sediment deposition, the results should not be viewed in isolation and a substantial body of purely qualitative observational data should supplement any planning or management decision.

At the end of the last ice age, Napeague was submerged under the sea . ( At that time, Montauk was an island . ) In the intervening several thousand years, ocean currents, or littoral drift, filled in this space with sand, giving rise to Napeague.

The abrupt change in the direction of the coast north of the lake, strong winds shifting sand to the shore, long shore drift ( littoral drift ), the presence or absence of strong river and tidal currents in different areas are the reasons attributed for the growth of the spit.

But the sand keeps flowing, carried not only by waves but also by a longshore current of sorts called a littoral drift . To keep sand from closing the inlets, people build groins jutting out into the ocean, on the up-current side of the littoral drift . And sure enough, the inlet stays open because sand piles up on the up-current side of the groin.

The source of heavy mineral sands is in a hardrock source within the erosional areas of a river which carries its load of sediment into the ocean, where the sediments are caught up in littoral drift or longshore drift . Rocks are occasionally eroded directly by wave action shed detritus, which is caught up in longshore drift and washed up onto beaches where the lighter minerals are winnowed.
