The whole Red Sea Coast of Saudi Arabia is projected with coastal fjords. These fjords referred to as lagoons range extensively in size. They are deemed to be erosional components created in the emergence of post-warm Wisconsin’ s. In the Red Sea, the dynamically increasing coral, the subsistence of fringing and barrier reefs take up an extremely crucial purpose in the extreme production of sediments that are reef and carbonates (Baghdadi, Ghazali & Khan, 2005). The Al-Shoaiba lagoon is endowed with a broad array of sediment texture varying from gravel to mud.

This is as a result of differing energy degrees in diverse environments of deposition in the lagoon. The tidal air motions at the entry of the lagoon are in general impacted by the energy and direction of the wind. They may achieve an utmost speed of approximately 80 cm/sec once in a while. This is clearly mirrored in the texture of the sediment at the entry where a gravel-rich tongue sand that is muddy is seen, flowing in a northerly direction subsequent to the passageway of the tidal motion of wind.

Moderately, sediments that are finer re-suspend by tidal, wave and wind and produce currents at the entry, are transported into the lagoon and deposited in an environment that is quiescent. The northwestern region of the lagoon is moderately calm where sand that is muddy is dominant (Dekker, 2001). Nevertheless, sand that is gravelly is established to be present in the northwestern region around one of the mangrove forests where substances that are finer are not trapped by the mangrove’ s roots are seen in other regions where root take up a significant function of trapping sediment that is light (Abrams, 2000).

Generally, sand is dominant at shallow depths in the southern, and northern fringes of the lagoon whilst mud dominates in deep waters. Because there is the inadequate flow of the river into the lagoon and minimal rainfall, the lagoon obtains extremely minimal or no terrigenous substance through streams that are seasonal. Carbonate sediments at the mouth of an entrance of the lagoon are largely detrital in basis.
