Any of a number of materials deposited at Earth's surface by physical agents (such as wind, water, and ice), chemical agents (precipitation from oceans, lakes, and rivers), or biological agents (organisms, living and dead).
(1) Loose, fragments of ROCKS, MINERALS or organic material which are transported from their source for varying distances and deposited by air, wind, ice and water. Other sediments are precipitated from the overlying water or form chemically, in place. Sediment includes all the UNCONSOLIDATED materials on the sea floor. (2) (SMP) The fine grained material deposited by water or wind.
Granular material of which a shore, riverbed or seabed is comprised. Sediment is moved on to, along and away from the shore by wind, waves and currents. It can be transported by air or water currents over the ground or seabed or may be carried in suspension in air or water. Fine sediment (silt or mud) settles slowly in low energy environments. Coarse sediment (sand or gravel) settles quickly and is transported in higher energy environments.
fragments of material produced by weathering and erosion of rocks. It is a major nonpoint source pollutant to which other pollutants may attach. Sediment is a problem for drinking water because sediment must be removed and diposed of. For related information visit: Clean Water & Your Health or Our Treatment Plants & Wells.
(1) Matter in water which can be removed from suspension by gravity or mechanical means. (2) A non-combustible solid matter which settles out at bottom of a liquid; a small percentage is present in residual fuel oils. SEGREGATION - The tendency of refuse of varying compositions to deposit selectively in difference parts of the unit.
Material (such as gravel, sand, mud, and lime) that is transported and deposited by wind, water, ice, or gravity; material that is precipitated from solution; deposits of organic origin (such as coal and coral reefs).
solid material that settles on the bottom of the container during fermentation; composed of dead yeast cells and other extraneous materials (bee legs, protein molecules, etc.) settling out of suspension.
loose particles of sand, clay, silt, and other substances that settle at the bottom of a body of water. Sediment can come from the erosion of soil or from the decomposition of plants and animals. Wind, water, and ice often carry these particles great distances.
means both mineral or organic material that is being, or has been moved from its site of origin by transporting agents such as water, wind and gravity to a lower position in the catchment, either above or below sea level.
An umbrella term for any small particles found in a liquid. In geological terms, this is often tiny particles of clay or sand found in rivers and other bodies of water, and later forming the basis of sedimentary rock.
The deposit that most red wines tend to throw as they age in bottle, it is as natural a part of an old wine as the shell is part of an egg. It should not be confused with cloudiness, haziness or lack of clarity, any of which often indicate that a wine is not fit to drink.
Solid fragmental matter, either inorganic or organic, that originates from weathering of rocks and is transported and deposited by air, water, or ice, or that is accumulated by other natural agents, such as chemical precipitation from solution or secretion from organisms. When deposited, it generally forms layers of loose, unconsolidated material (for example, sand, gravel, silt, mud, till, loess, alluvium).
a mass of organic or inorganic solid fragmented material, or the solid fragment itself, that comes from weathering of a rock and is carried by, suspended in, or dropped by air, water or ice; or a mass that is accumulated by any natural agent that forms in layers on the earth's surface such as sand, gravel, silt, mud, fill or loess. A solid material that is not in solution and either is distributed through the liquid or has settle out of the liquid
Solid material that has settled down from a state of suspension in a liquid; solid fragmental material transported and deposited by wind, water, or ice, chemically precipitated from solution, or secreted by organisms, and that forms in layers in loose unconsolidated form.
Unconsolidated solid material that originates mostly from disintegrated rocks and is transported by water or air. Also, it may include chemical and biochemical precipitates or decomposed organic material, such as humus.
Unconsolidated particles, ranging from clay-size to boulders, produced by the breakdown of rocks that may be carried by natural agents (wind, water, and ice), and eventually deposited to form sedimentary deposits. Organisms and chemical precipitation can also produce sediment.
Loose particles of sand, clay, silt, and other substances that settle at the bottom of a water body. They come from eroding soil and from decomposing plants and animals. Wind, water, and ice often carry these particles great distances. Many sediments in rivers, lakes, and oceans are contaminated by pollutants, such as DDT and PCBs.
Sediment is made up of minerals that were dissolved in the water, but have precipitated out when the water was heated, settling into the bottom of the tank. Sediment can be as fine as sand or come in chunks. It can burn out the lower element in electric water heaters. It also is the source of noise when a tank is firing, which can be quite disconcerting to those who don't know what it is. Noise merely means there is sediment and the amount of noise is not proportional to the amount of sediment.
Particulate material, both mineral and organic, that is in suspension, being transported, or has been moved from its site of origin by the forces of air, water, gravity, or ice, including material deposited in a loose, unconsolidated form on the bottom of a water body. The term dredged material refers to material that has been dredged from a water body, while the term sediment refers to material in a water body prior to dredging.
Compare? Topsoil, sand, and minerals washed from the land into water, usually after rain or snow melt. Sediments collecting in rivers, reservoirs, and harbors can destroy fish and wildlife habitat and cloud the water so that sunlight cannot reach aquatic plants. Loss of topsoil from farming, mining, or building activities can be prevented through a variety of erosion-control techniques.
Solid unconsolidated rock and mineral fragments that come from the weathering of rocks and are transported by water, air, or ice and form layers on the Earth's surface. Sediments can also result from chemical precipitation or secretion by organisms.
Usually refers to residue left by wine, particularly red, as it ages, consisting mainly of pigments and tannins, but can also refer to the solid particles which settle out of a wine at any stage of wine production.
Material, such as sand, silt, or clay, suspended in or settled on the bottom of a water body. Sediment input to a body of water comes from natural sources, such as erosion of soils and weathering of rock, or as the result of man's activities, such as forest or agricultural practices, or construction activities.
The gritty deposit that collects in the bottle of older red wines. It is a natural part of aging. Wines with sediment should stand upright for several hours before serving, and then be decanted off of the settled sediment.
(a) Solid fragmental material that originates from weathering of rocks and is transported or deposited by air, water, or ice, or that accumulates by other natural agents, such as chemical precipitation from solution or secretion by organisms, and that forms in layers on the Earth's surface at ordinary temperatures in a loose, unconsolidated form, e.g. sand, gravel, silt, mud, till, loess, alluvium. (b) Strictly, solid material that has settled down from a state of suspension in a liquid.
Solid material, both mineral and organic, that is in suspension, is being transported, or has been moved from its sit of origin by air, water, gravity, or ice and has come to rest on the earth's surface, either above or below sea level.
fragments of rock, soil, and organic material transported and deposited in bed by water, wind, or other natural phenomena. The term can refer to any size of particles but is often used to indicate only fragments smaller than 6 mm.
(Rock formed from) solid material, whether mineral or organic, which has been moved from its position of origin and redeposited - often created by weathering processes, such as sandstone and shale, or deposited by chemical processes, such as salt or limestone.
The deposits that occur in an old red wine. They look kind of like coffee grains and are bitter tasting. Sediment is expected in great, old wines, and correct decanting keeps the sediment from entering your glass.
Soil particles suspended in and carried by water as a result of erosion. The particles are deposited in areas where the water flow is slowed such as in harbors, wetlands, and lakes. This process is referred to as sedimentation.
Material that is too dense to remain suspended and settles to the bottom of a liquid, The sediment usually originates from the remains of phytoplankton, zooplankton and other aquatic organisms, from erosion of surrounding lands, or from chemical precipitation of dissolved minerals. [Lat. sedimentum, from sedeo, to settle.
Soil, sand, and minerals washed from land into water, usually after rain. Sediment can accumulate in reservoirs, rivers and harbors, destroying fish and wildlife habitat, and clouding the water so that sunlight cannot reach aquatic plants. Careless farming, mining, and building activities will expose sediment materials, allowing them to wash off the land after rainfall.
Solid material (silt, sand, or organic matter) that has been moved from its site of origin and has settled to the bottom of a watercourse or water body. Excessive amounts can clog a watercourse. If disturbed, it can contribute to turbidity.
Soil, sand, and minerals washed from land into water, usually after rain. Sediment can destroy fish-nesting areas, clog animal habitats, and cloud waters so that sunlight does not reach aquatic plants.
Materials such as soil, sand, and silt that are washed from land into water, usually after rain. The particles are deposited in areas where the water flow is slowed such as in harbors, wetlands, and lakes.
Soil or rock particles that have been transported to stream channels or other bodies of water. Sediment input comes form natural sources, such as soil erosion, rock weathering, agricultural practices, or construction activities.
The natural aging process of red wines causes a deposit to accumulate in the bottle. This is not a flaw in the wine. Sediment is composed of tannins and pigments that precipitate out of solution. Older wines are decanted to separate the wine from its sediment.
any material having a geological origin and comprised of small particles. The size of the individual particles determines the description of the sediment and it can range from fine clay to coarse gravel.
1. An accumulation of rock and mineral particles transported by water (fluvial sediment) or by wind ( aeolian sediment). 2. A collective term for rock and mineral particles that 1) are being transported by a fluid (sediment in transport, suspension, or motion) caused by the fluid motion or 2) have been deposited by the fluid (i.e., sediment deposits).
Loose, unconsolidated material of the following compositions: 1. Rock fragments (also called clasts) transported by wind, moving water, or moving ice, such as sand 2. Chemical precipitates from solution, such as salt 3. Organic secretions or accumulation, such as coal
Solid matter that has settled in the bottom of a container of wine, whether it be bottle, fermentation tank or storage vessel. When it occurs in bottles of fine, aged red wine, sediment is not a result of poor filtration but is a natural part of the maturation process as phenolic compounds like tannins polymerize to the point where they can no longer remain suspended in the wine. Mature vintage port is an example of a wine that will invariably contain sediment, and like all such wines should be handled carefully and decanted prior to serving.
Sediment is any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bed or bottom of a body of water or other liquid. Sedimentation is the deposition by settling of a suspended material.
