capillary water
31capillary fringe — The lower subdivision of the unsaturated zone immediately above the water table in which the interstices are filled with water under pressure less than that of the atmosphere, being continuous with the water below the water table but held… …
32Water table — The water table is the level at which the ground water pressure is equal to atmospheric pressure. It may be conveniently visualized as the surface of the ground water in a given vicinity. It usually coincides with the phreatic surface , but can… …
33capillary fringe zone — The zone above the free water elevation in which water is held by capillary action …
34capillary head — The potential, expressed in head of water, that causes the water to flow by capillary action [22] …
35capillary zone — /kəˈpɪləri zoʊn/ (say kuh piluhree zohn) noun the zone immediately above the watertable into which water may be drawn by capillary action. Also, capillary fringe …
36water table — 1. the planar, underground surface beneath which earth materials, as soil or rock, are saturated with water. 2. Archit. a projecting stringcourse or similar structural member placed so as to divert rain water from a building. Also, watertable.… …
37capillary conductivity — 1. The property of an unsaturated porous medium to transmit liquid [22]. 2. Coefficient which expresses the extent to which an unsaturated permeable medium allows flow of water through its interstices, under a unit gradient of capillary… …
38capillary action — the upward movement of water through a channels in a substance. In geography, most commonly the upward movement of water through a soil. Caused by adhesion of the water to the channel surface and cohesion of water molecules to one another …
39capillary interstice — An interstice small enough to hold water by surface tension at an appreciable height above a free water surface, yet large enough to prevent molecular attraction from extending across the entire opening …
40capillary movement — The rise of water in the subsoil above the water table by capillarity …
