Characteristics and Motion of Sédiments
2.1 Introduction
Sédiment is any matter in the form of minute separate particles or substance which can be transported by the fluid flow and is ultimately placed
as a section of solid éléments on the seabed or beneath the surface of a body
of water or any other liquid. The process of sédimentation can be simply
understood as the déposition of suspended particles by settling. Whereas,
mud can be defined as, “4 sédiment water mix which consists of materials
that are mainly less than 63 pm in size, exhibits poroelastic or viscoelastic
rheological behaviour when the mixture is material-supported, and when it
is fluid state it is highly viscous and non-Newtonian”. Very fine particles
or sédiments in both Coastal and inland waters is a matter of widespread
attention rising from its importance in the up keeping of navigational channels and in regulating the Coastal process. Sédiments also influence the
coarseness and the résistance of flow due to friction in waterways transport, thereby, leading to the complex problem of stage-discharge-sediment
transport relationships.
Océans comprise of a vast réceptacle of land-driven (terrigenous) and
comparatively lower proportions materials from volcanic and hydrothermal events (substances thrown out by the volcano). The insoluble materials from the fragmented sédiments are left after the breakdown due to
Chemical failure in bond and breakdown of the pre-existing rocks, which
includes silicate minerais, majorly constituting quartz element. The interaction among the atmosphère, lithosphère, and astronomical influence leads
to a restless dynamic oceanic System, leading to complex physical and
Chemical processes; biological action; and the océan waves, tides, and entrent circulation. When the océan waters disperses its energy sufficiently
such that it is incapable of keeping the sédiments in suspension, results in
déposition.
