Apr 16, 2018· Littoral Cell A littoral cell is a distinct area of the coastline where sand enters the ocean, flows down the coast, and then is removed from the system Permanent loss of sand occurs at the end of the littoral cell when it flows into a submarine canyon or, less frequently, when it accumulates on shore as part of a sand dune

Sedimentary budget - Wikipedia

To assess the sedimentary budget the coast has to be divided into two separate morphologies, commonly known as littoral cells and compartments Sediment compartments can usually be defined as two rocky barriers which mark the ends of a beach and have a fixed sediment budget, although usually leaky to some extent Littoral cells can either be .

Littoral zone - Wikipedia

The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged The littoral zone always includes this intertidal zone, and
