The average length of time that an atom of a particular element spends in a reservoir before leaving.
The time required for a water body to exchange its entire volume of water. Lake Michigan takes about 99 years to flush its entire volume. This is an important factor used in determining the residence time of toxic pollutants in the lake. Also referred to as flushing time.
Period of time that groundwater remains in an aquifer.
The length of time water remains in a waterbody. Generally the same as flushing time.
the length of time that AMD remains in a treatment pond, wetland, ditch or other structure. Designed residence times depend on the incoming flow rate, the rate of treatment process in the structure, the contaminants in the AMD to be treated, the size of the structure, and the settling rate of solids in the discharge.
The amount of time that water or substances in the water stay in an area
The length of time a water molecule remains in a given hydrologic compartment.
The time during which a pressure sensitive material remains on a surface before testing for adhesive permanence or removability.
amount of time water remains inside a specified area, e.g., harbor, bay, etc.
the period of time spent in a particular place
The average length of time a substance spends in given reservoir that is at a steady stare with respect to the processes that add and remove the substance to and from the reservoir. Residence time is calculated as the ratio of the reservoir size to the rate of inflow or outflow (which are equal at steady state).
The length of time between the input of water as infiltration or recharge and its output as runoff or discharge. Also known as transit time or turnover time.
The period of time that a volume of liquid remains in a tank or system.
The average time a hypothetical particle of water spends in solution between the time it first enters and the time it is removed from a coastal waterway.
The time taken by a method to execute.
The time, in seconds, required for the flaming front of a fire to pass a stationary point at the surface of the fuel. The total length of time that the flaming front of the fire occupies one point.
Length of time that a pollutant remains within a section of a stream or river. The residence time is determined by the streamflow and the volume of the river reach or the average stream velocity and the length of the river reach.
The average time a component remains in a continuous-process mixing environment.
time required for a solvent to reach the ozone layer from earth.
The length of time the fuel remains in a combustion zone.
The average length of time that water stays in a reservoir or lake, also called the hydraulic residence time. It is usually calculated by dividing the volume of the waterbody by the average annual out flow. In the Atlas, the estimate of residence time usually did not consider groundwater inflow or outflow, because they have not been measured in most lakes.
Residence time is the length of time that the material is held at melt range temperatures in the barrel.
The average length of time that a molecule of water or a chemical within the water, such as phosphate, remains in a lake.
The length of time a component, such as an individual water molecule, spends in a particular compartment or location before it moves on through a particular process or cycle.
The length of time required for the flaming zone or fire front of a spreading forest fire to pass a given point, most commonly expressed in minutes (min) and/or seconds (s). Numerically, it is equal to the flame depth divided by the rate of spread. Note Burn-out Time.
The average length of time that a substance stays in a particular reservoir.
The time (seconds) required for the Fire Front to pass a stationary point at the surface of the fuel. Numerically, it is the Flame Depth divided by the rate of spread.
A measure of the length of time that molecules will stay in a chamber or region. It can be estimated by dividing the volume of a chamber or region by the volumetric flow rate through it. For example, the residence time of air in clouds is important for aqueous-phase chemical reactions and for the size to which hydrometeors can grow.
Residence time is a broadly useful concept that expresses how fast something moves through a system in equilibrium. It is the average time a substance spends within a specified region of space, such as a reservoir. For example, the residence time of water stored in deep groundwater, as part of the water cycle, is about 10,000 years.
