Sedimentation - Wikipedia

In geology, sedimentation is the deposition of particles carried by a fluid flow. For suspended load, this can be expressed mathematically by the Exner equation, and results in the formation of depositional landforms and the rocks that constitute sedimentary record. An undesired increased transport and sedimentation of suspended material is called siltation, and it is a major source of pollution in waterways in some parts of the world. High sedimentation rates can be a result of poor land management and a high frequency of fl

Black Warrior Riverkeeper - Siltation Sedimentation

Sedimentation, or siltation, is one of the most severe threats to the Black Warrior River. The primary sources of this muddy water are irresponsible development projects, reckless logging and mining operations, and poorly built and maintained roads.

Responses of coral reefs and reef organisms to sedimentation

Sedimentation can alter the complex interactions between fish and their reef habitat. For example, sedimentation can lull major reef-building corals, leading to eventual collapse of the reef framework. A decline in the amount of shelter the reef provides leads to reductions in both number of individuals and number of species of fish.

Sedimentation (sometimes called siltation) results when greater than normal quantities of fine particles of sediment, silt or clay (mud) get introduced into the water. Depending on the size of the particles and the velocity of the water, the sediments may stay in suspension for a long time and be carried downstream for many kilometers.
