In addition, the direction of the littoral drift prevents deltaic sediments of the Atrato River from being distributed along the coasts of the gulf.
Their quays and breakwaters largely block the natural littoral drift and cause rapid accumulation to the south of these harbours and extensive erosion to the north of the latter.
The littoral drift quantities are higher from May to October, due to heavy breakers associated with the SW monsoon season.
This strategy of construction of permanent, hard engineering structures has successively changed the circulation of sediments by littoral drift and has partially conditioned the type of response from the coastline.
Although littoral drift generally carries sediments to the bayheads, even the healthiest sections of the coast at the bayheads are from time to time subject to erosion.
There is no evidence for volumetrically significant sources of beach grade sediment along the Lake Michigan shore in the study areas other than that moving in the littoral drift and derived, by erosion, from the upland bluffs and dunes.
Since then, channel depths have decreased in varying amounts due to sedimentation and littoral drift
The key words are wave measurements and modelling, wind and ship waves, wave asymmetry, fast ferries, littoral drift, coastal erosion, sedimentation processes, port terminals, underwater irradiation, coastal winds and off-shore wind parks.
The process is called littoral drift. But seawalls can alter the littoral drift.
Also, an additional 80,000 cubic yards of stamp sands will be removed from the ancient riverbed area north of Buffalo Reef known as the trough in order to delay further sedimentation by the littoral drift in the stamp sands into the reef and the juvenile whitefish recruitment area south of the harbor.
