The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume. The residence time of a set of parcels is quantified in terms of the frequency distribution of

Hydraulic conductivity
Videos
In science and engineering, hydraulic conductivity is a property of porous materials, soils and rocks, that describes the ease with which a fluid can move through the pore space, or fracture network.
Residence time
…through groundwater. The amount of time that a pollutant spends traveling through a delineated subsurface space is related to the saturation and the hydraulic conductivity of the soil or rock. Porosity is another significant contributing factor to the mobility of water through the ground (e.g. toward the water table). The…
