Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

For example, sand and silt can be carried in suspension in river water and on reaching the sea bed deposited by sedimentation. Definition: Suspension is a method of transporting very fine sediment in a river. The suspended load of a flow of fluid, such as a river, is the portion of its sediment uplifted by the fluid's flow in the process of sediment transportation.It is kept suspended by the fluid's turbulence.The suspended load generally consists of smaller particles, like clay, silt, and fine sands Test Your Knowledge - and learn some interesting things along the way. It can be as small as a grain of sand or as large as a boulder. Longshore drift This is the net lateral transport of material along the coastline when waves approach the coast at an angle. They can be considered as a closed coastal sub-system as far as sediment is concerned. A sediment cell is a largely self-contained stretch of coastline. Sediment is fine-grained particles like silt and clay, generally occurring as a result of soil erosion. This page was last changed on 3 October 2020, at 16:13.

Continental shelves are for the most part formed of sediment deposits that may reach thicknesses in excess of 1 km. Meaning of SEDIMENT. The physics of the most common sedimentation process, the settling of solid particles from fluids, has long been known. Incoming swash transports sediment up the beach at an angle (movement contains an up-beach component and a lateral component) Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier).If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. They are often determined by the topography and shape of the coastline which directs the movement of the sediment within the cell. Sediment cells are areas along the coastline and in the nearshore area where the movement of material is largely self-contained. This transported material is called sediment.

Around the coast of England and Wales there exist 11 sediment cells: largely self-contained sediment systems around which sediment is recycled. Lithification is how soft sediments, the end product of erosion, become rigid rock ("lithi-" means rock in scientific Greek).It begins when sediment, like sand, mud, silt and clay, is laid down for the last time and becomes gradually buried and compressed under new sediment. Each sediment major cell typically has many smaller sub-cells. Minerals deposited from water in the spaces between the sediment grains gradually cements them together. Sediments may include: fragments of other rocks that often have been worn down into small pieces, such as sand, silt, or clay. In reality, some sediment does get transferred between neighbouring cells. BSL Geography Glossary - Suspension - definition.
