Cline (hydrology)



In hydrology and related studies, a cline is a comparatively thin, typically horizontal layer within a fluid, in which a property of the fluid varies greatly over a relatively short vertical distance.

Such clines and the respectively varying properties include:


 * Chemocline - chemistry
 * Halocline - salinity
 * Lysocline - dissolution of calcite
 * Pycnocline - density
 * Thermocline - temperature
