Siphon (caving)
In caving referred to siphon one under water standing cave part .
A distinction can be made between permanent siphons, in which there is permanent water, and temporary siphons, which are only filled when the water level is increased .
Cave parts that have relatively little space between the water surface and the cave ceiling are sometimes referred to as half siphons .
If the cave passage continues at the end of the well-known air-filled area under the water surface, it is also called an end siphon. This attribution can become obsolete through further research , as soon as a subsequent air-filled space above the water surface is found (for example) by a newly found bypass or a dive .
Siphons with a sinusoidal height profile are characterized by an accumulation of coarse sediment in the descending branch and fine in the ascending branch.
