Sedimentation
Water exiting the flocculation basin enters the sedimentation basin, also called a clarifier. It is a large tank with slow flow, allowing floc to settle to the bottom.
Sediment Yield: The quantity of sediment arriving at a specific location.
Sedimentation: Letting solids settle out of wastewater by gravity during treatment.
Sediment: Topsoil, sand, and minerals washed from the land into water, usually after rain or snow melt.
Sediment Yield: The quantity of sediment arriving at a specific location.
Sediments
Soil, sand, and minerals washed from land into water, usually after rain. They pile up in reservoirs, rivers and harbours, destroying fish and wildlife habitat, and clouding the water so that sunlight can- not reach aquatic plants.
Sedimentation: The removal, transport, and deposition of detached soil particles by flowing water or wind. Also, the process of solid particles settling out of water and wastewater treatment processes.
Sedimentation
The settling of solids in a body of water using gravity.

Sediment - Particles carried by water or air that are deposited in other areas or elevation are called sediment.
sedimentation A water treatment process in which solid particles settle out of the water being treated in a large clarifier or sedimentation basin.
Sediment - 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.
Sediments Soil, sand, and minerals washed from land into water, usually after rain.
Semi-confined aquifer An aquifer partially confined by soil layers of low permeability through which recharge and discharge can still occur.
Sediment: eroded soil and rock material, and plant debris, transported and deposited by water.
Septic Tank: sewage disposal tank in which a continuous flow of waste material is decomposed by anaerobic (in the absence of oxygen) bacteria.
sedimentation
the deposition of suspended matter carried by water, wastewater, or other liquids, by gravity. It is usually accomplished by reducing the velocity of the liquid below the point at which it can transport the suspended material.
Sediment
The soil, sand and minerals at the bottom of surface waters, such as streams, lakes and rivers. Sediments capture or adsorb contaminants. The term may also refer to solids that settle out of any liquid.
sediment yield. The quantity of sediment arriving at a specific location.
seize up. Seize up occurs when an engine overheats and a part expands to the point where the engine will not run. Also called "freezing". ...
Sediment: Fine soil or mineral particles.
Side Channel: A flood channel or abandoned stream channel connected to a stream or river at periods of high flow. Serves juvenile fish as rearing habitat and refuge from floods.
Sediment particles resting on or near the channel bottom that are pushed or rolled along by the flow of water.
Bedrock
Any solid rocks exposed at the surface or overlain by unconsolidated materials.
Sedimentation The gravity settling, and thus removal, of materials more dense than the suspending fluid.
Sedimentation basin. See clarifier.
Sediment from drnking water treatment in Newport News, Virginia is applied to loblolly pine plantations instead of being sent to landfills.
SEDIMENTATION
Soil particles suspended in stormwater that can settle in stream beds and disrupt the natural flow of the stream.

Term example: sedimentation
Definition: Deposition of material of varying size, both mineral and organic, away from its site of origin by the action of water, wind, gravity or ice.
SAC (See special area of conservation) ...
cycle, sedimentary the cyclical exchange of an element between (1) the stores of that element found primarily in rock, soil, and in solution in aquatic systems (e.g., phosphorus), and (2) the living plants, animals, ...
Terrigenous: Sediment and water derived from the land by erosive processes ...
Beach
A sloped sediment shoreline composed of sand, gravel, cobble, mud, or boulder-sized sediments, sometimes with beach rock.
Clarifiers are also called SETTLING BASINS and SEDIMENTATION BASINS.
class (pipe and fittings). The working pressure rating of a specific pipe for use in water distribution systems which i includes allowances for surges.
Limestone - a sedimentary rock consisting chiefly of calcium carbonate, primarily in the form of calcite.
Loam - a soil texture that is about equally influenced by sand, silt, and clay and containing good amounts of organic matter.
The four reservoirs, regions of the Earth in which carbon behaves in a systematic manner, are the atmosphere, terrestrial biosphere (usually includes fresh water systems), oceans, and sediments (includes fossil fuels).
Seed bank The population of viable dormant seeds that accumulates in and on soil and in sediments under water.
They are typical in igneous, volcanic, metamorphic, and granitic terrane as well as chemical sediments such as limestone, anhydrite and gypsum. Tubular springs are more typical in chemical sedimentary rock and from lava tubes in basalt flows.
(2) A geomorphologic feature characterized by a cone or fan-shaped deposit of boulders, gravel, and fine sediments that have been eroded from mountain slopes, transported by flood flows, and then deposited on the valley floors, ...
These are forms of diffuse pollution caused by sediment, nutrients, organic and toxic substances originating from land use activities which are carried to lakes and streams by surface runoff.
What is it?
A tube of sediment (sand and mud) that scientists drill from the floor of an ocean or lake. Sediment builds up in layers over time. Rocks and fossils stuck in the sediment provide clues about past climate trends.
The levee results from periodic 'over-bank' flooding where coarser sediment is immediately deposited or dumped, while the finer sediments flow over a further distance.
Note 2: A primary pollutant is one emitted into the atmosphere, water, sediments or soil from an identifiable source.
Note 3: A secondary pollutant is a pollutant formed by chemical reaction in the atmosphere, water, sediments, or soil.
Porosity: The capacity of soil or rock to hold water. The ratio of the volume of void spaces in a rock or sediment to the total volume of the rock or sediment. DIAGRAM
Potable water: Suitable for human consumption as drinking water.
Aquifer: A porous, water-saturated layer of sediment and bedrock under the Earth's surface; also described as artesian (confined) or water table (unconfined).
Drainage Basin- The area of land that drains water, sediment, and dissolved materials to a common outlet at some point along a stream channel.
Terracing: Dikes built along the contour of sloping farm land that hold runoff and sediment to reduce erosion.
Primary treated water. First major treatment in a wastewater treatment facility, usually sedimentation but not biological oxidation.
Waters around the reef suffer from large quantities of effluents, pesticides and sediment from sugar farms, and the reef itself is threatened by the clearing of land, which has destroyed the wetlands that are an integral part of the reef's ecology.
Clear Cut
Harvesting all the trees in one area at one time, a practice that destroys vital habitat and biodiversity and encourages rainfall or snowmelt runoff, erosion, sedimentation of streams and lakes, and flooding. ...
"Non-point" sources include runoff from land treated with pesticides, fertilizers or herbicides, car exhaust, contaminated sediments, storm water runoff, atmospheric deposits and domestic sewage5.
Increased amounts of rainfall would quickly wash the carbon dioxide out of the atmosphere. Thick layers of abiotic carbonate sediment which can be found on top of the glacial rocks from this period are believed to have been formed by this rapid ...
