Record 2 2012-04-13

English

Subject field(s)
  • Hydrology and Hydrography
  • Fluid Mechanics and Hydraulics (Physics)
DEF

The phenomenon of gravity flow of a liquid relative to another liquid, or of relative flow within a liquid medium due to difference in density. [Definition standardized by ISO.]

CONT

A density current flows because of the pull of gravity and the density difference, and it stops moving when the two fluids mix, or when the current uses up its energy.

CONT

Density currents are of considerable practical importance. For example, the deposition of sediment from turbidity currents—i.e., density currents in which the density difference is caused by suspended sediment—in lakes may result in a rapid decrease of reservoir capacity. Equally significant, the industrial discharge of large amounts of heated water may generate density currents that have adverse effects on neighbouring human or animal communities. Because of such considerations, many experimental studies on the properties of density currents have been undertaken.

OBS

density current: term standardized by ISO.
