What does CFS stand for in Water? They differ from state to state and often depend on whether the water is a river, lake, or ocean. kilowatthour (KWH)--a power demand of 1,000 watts for one hour. potentiometric surface/piezometric surface--the imaginary line where a given reservoir of fluid will "equalize out to" if allowed to flow; a potentiometric surface is based on hydraulic principles. Large watersheds, like the Mississippi River basin contain thousands of smaller watersheds. estuary--a place where fresh and salt water mix, such as a bay, salt marsh, or where a river enters an ocean. For example, if the Fox River is running into the Chain O' Lakes at 14,000 CFS, but leaving the Chain at 9,000 CFS, that means the lake will continue to fill because more water is coming in than going out. Thus, turbidity makes the water cloudy or even opaque in extreme cases. About 85% of domestic water is delivered to homes by a public-supply facility, such as a county water department. cubic feet per second (cfs)--a rate of the flow, in streams and rivers, for example. surface tension--the attraction of molecules to each other on a liquid's surface. It is accomplished by bringing together waste, bacteria, and oxygen in trickling filters or in the activated sludge process. groundwater, confined--groundwater under pressure significantly greater than atmospheric, with its upper limit the bottom of a bed with hydraulic conductivity distinctly lower than that of the material in which the confined water occurs. suspended-sediment concentration--the ratio of the mass of dry sediment in a water-sediment mixture to the mass of the water-sediment mixture. flood, 100-year--A 100-year flood does not refer to a flood that occurs once every 100 years, but to a flood level with a 1 percent chance of being equaled or exceeded in any given year. geyser--a geothermal feature of the Earth where there is an opening in the surface that contains superheated water that periodically erupts in a shower of water and steam. The water year used by the U.S. Geological Survey runs from October 1 through September 30, and is designated by the year in which it ends. So, when you hear that a river crested at 14.5 feet, it does not mean the river is 14.5 feet deep. It is equal to a volume of water one foot high and one foot wide flowing a distance of one foot in one second. Generally, any viruses, bacteria, or fungi that cause disease. No data point selected. well (water)--an artificial excavation put down by any method for the purposes of withdrawing water from the underground aquifers. Xeriscaping is becoming more popular as a way of saving water at home.More on xeriscaping: Colorado WaterWise Council. As a result of their persistence, they tend to accumulate in the environment. Gage height is often used interchangeably with the more general term, stage, although gage height is more appropriate when used with a gage reading. levee--a natural or manmade earthen barrier along the edge of a stream, lake, or river. Most are simple ditches with dirt banks, but they can be lined with concrete. withdrawal--water removed from a ground- or surface-water source for use. desalination--the removal of salts from saline water to provide freshwater. All are based upon carbon compounds. Riparian rights cannot be sold or transferred for use on nonriparian land. The value is determined by multiplying the cross sectional area of the stream, in square feet, times the speed or velocity of the water… This unit is commonly used to represent pollutant concentrations. A geological formation or structure that stores and/or transmits water, such as to wells and springs. The diversion figure in water right applications is the quantity of water expressed as a flow rate in cfs (cubic feet per second) and/or as a volume in acre-feet to be taken from a well, river, spring, etc. gage height--the height of the water surface above the gage datum (zero point). The Illinois River serves as a tributary to the Mississippi River. In terms of streams and rivers, PCBs are drawn to sediment, to which they attach and can remain virtually indefinitely. watthour (Wh)--an electrical energy unit of measure equal to one watt of power supplied to, or taken from, an electrical circuit steadily for one hour. The osmosis process occurs in our bodies and is also one method of desalinating saline water. recharge--water added to an aquifer. Water with a pH of 7 is neutral; lower pH levels indicate increasing acidity, while pH levels higher than 7 indicate increasingly basic solutions.View a diagram about pH. irrigation--the controlled application of water for agricultural purposes through manmade systems to supply water requirements not satisfied by rainfall. What does CFS stand for? solvent--a substance that dissolves other substances, thus forming a solution. atmosphere--layers of gases which surround the Earth. hydroelectric power water use--the use of water in the generation of electricity at plants where the turbine generators are driven by falling water. drip irrigation--a common irrigation method where pipes or tubes filled with water slowly drip onto crops. The complete wastewater treatment process typically involves a three-phase process: (1) First, in the primary wastewater treatment process, which incorporates physical aspects, untreated water is passed through a series of screens to remove solid wastes; (2) Second, in the secondary wastewater treatment process, typically involving biological and chemical processes, screened wastewater is then passed a series of holding and aeration tanks and ponds; and (3) Third, the tertiary wastewater treatment process consists of flocculation basins, clarifiers, filters, and chlorine basins or ozone or ultraviolet radiation processes. Top CFS abbreviation meanings updated October 2020. outfall--the place where a sewer, drain, or stream discharges; the outlet or structure through which reclaimed water or treated effluent is finally discharged to a receiving water body. Chlorine is often added to discharges from the plants to reduce the danger of spreading disease by the release of pathogenic bacteria. (2) the water upstream from a structure or point on a stream. return flow--(1) That part of a diverted flow that is not consumptively used and returned to its original source or another body of water. reach--any length of a stream or river. It is compiled from a number of sources and should not be considered an "official" U.S. Geological Survey water glossary. Streamflow (also known as discharge) is the volume of water flowing past a given point in the stream in a given period of time. The doctrine of Prior Appropriation was in common use throughout the arid west as early settlers and miners began to develop the land. groundwater, unconfined--water in an aquifer that has a water table that is exposed to the atmosphere. Here are some common terms used to describe flooding on the Des Plaines, Fox River and Chain O' Lakes and what they mean: CFS: Short for cubic feet per second. CFS. CFS stands for cubic feet per second which is a unit of measurement referring to the volume and speed of water flow. Floods have two essential characteristics: The inundation of land is temporary; and the land is adjacent to and inundated by overflow from a river, stream, lake, or ocean. We apologize for any inconvenience this may have caused. Land alongside rivers can be protected from flooding by levees. The rights can be lost through nonuse; they can also be sold or transferred apart from the land. seepage--(1) The slow movement of water through small cracks, pores, Interstices, etc., of a material into or out of a body of surface or subsurface water. For water that is stored or impounded, the acre-foot (af) is how water is measured. This process differs from electrodialysis, where the salts are extracted from the feedwater by using a membrane with an electrical current to separate the ions. milligrams per liter (mg/l)--a unit of the concentration of a constituent in water or wastewater. aquifer (confined)--soil or rock below the land surface that is saturated with water. See flowing well. These zones differ from an aquifer, where the pores are saturated with water. base flow--sustained flow of a stream in the absence of direct runoff. For example, the 20th percentile is the value below which 20 percent of the observations may be found. Cubic Feet Per Second Oil, Gas, Oilfield. Water for commercial uses comes both from public-supplied sources, such as a county water department, and self-supplied sources, such as local wells. A marsh may be prone to flooding during wet seasons. A general term for solid rock that lies beneath soil, loose sediments, or other unconsolidated material. Also, the volume of water added by this process. self-supplied water--water withdrawn from a surface- or groundwater source by a user rather than being obtained from a public supply. A basic primer on cfs: The number of CFS (Cubic Feet per Second) is a measure of the volume of water passing a specific point each second of time. Turbidity is based on the amount of light that is reflected off particles in the water. vapor--created when a substance (such as water) is in a gas state. conveyance loss--water that is lost in transit from a pipe, canal, or ditch by leakage or evaporation. Solid material in sewage also settles out in this process. UPDATE November 6, 2020 5:00 pm ET: A fix has been deployed for the issue impacting the delivery of real-time data to NWISWeb which occurred on November 1, 2020. organic matter--plant and animal residues, or substances made by living organisms. This is the volume of water flowing. sediment), dissolved chemicals (e.g. giardiasis--a disease that results from an infection by the protozoan parasite Giardia Intestinalis, caused by drinking water that is either not filtered or not chlorinated. thermal pollution--a reduction in water quality caused by increasing its temperature, often due to disposal of waste heat from industrial or power generation processes. tertiary wastewater treatment--selected biological, physical, and chemical separation processes to remove organic and inorganic substances that resist conventional treatment practices; the additional treatment of effluent beyond that of primary and secondary treatment methods to obtain a very high quality of effluent. jÓ½SØ÷>“èû;ï¢ İB+èbóÂÊÈo)�乄ÈÊ0�O”û«ÍT$ì¿KãnïÆ+ÄŠ%¡Ènô½c+Ú÷¾0[òè:N°cª«{dçÅ¡‚:ôH­è@&�#`Ø4³ �Ç ŒÃ&ñ%¯øpÀCÒtA(´@kI+£òËü‘̤…/%oå2LÓ@İ5M“p@80Á…Šš:Éï…HÆÑÃä*Oó]A?ÍÓx¹Rã AM¢/CO5Dÿ PhU;(Î8 µšb*•ïQ°ôœD:ʨ­Asõ-EÕZøğašËÚ"©5k’è×ÏN¶î+!ªÔğƒHæ1�ÀÎ2ªjÀılkÈ×Eª£ºÁ’= -ê‚¥U®ËõyUUË hydrologic cycle--the cyclic transfer of water vapor from the Earth's surface via evapotranspiration into the atmosphere, from the atmosphere via precipitation back to earth, and through runoff into streams, rivers, and lakes, and ultimately into the oceans. The fatigue worsens with physical or mental activity, but doesn't improve with rest. unsaturated zone--the zone immediately below the land surface where the pores contain both water and air, but are not totally saturated with water. For instance, rainfall that seeps into the ground. storm sewer--a sewer that carries only surface runoff, street wash, and snow melt from the land. saline water--water that contains significant amounts of dissolved solids.
