Siltation is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable.
Siltation refers to the process where river water deposits silt into reservoirs, leading to environmental issues such as reduced water storage capacity. It is often caused by sedimentation from the catchment area due to activities like shifting cultivation and overgrazing.
Siltation refers to the accumulation of fine sediment in a river system, which is caused by natural processes such as soil erosion, sediment transportation, deposition, and compaction. It is primarily contributed by the deposition of fine sediment and sediment movement during extreme floods.
Siltation. The process or action of depositing sediment. Sediment is composed of solid material, mineral or organic, and can be of any texture. The material has been moved from its site of origin by the forces of air, water, gravity, or ice and has come to rest on the earth's surface.
25 kwi 2017 · Siltation occurs as a result of human activities that leads to fine soil leaching into nearby rivers. This results in an unnaturally large accumulation of silt that stays in that particular area of that river. Rainstorms may also transport these soils into other water sources.
Siltation of Onshore Ocean Waters. A flow of silt into the oceans results from timbering operations, construction, and other human activities in coastal zones. Siltation leads in the tropics to the destruction of coral reef ecosystems by smothering the coral organisms. This in turn leads to the loss of local fisheries and ecotourism opportunities.
noun. ˈsilt. Synonyms of silt. 1. : loose sedimentary material with rock particles usually ¹/₂₀ millimeter or less in diameter. also : soil containing 80 percent or more of such silt and less than 12 percent of clay. 2. : a deposit of sediment (as by a river) silty.
