Threshold depth
Drempeltiefe is a term used in lock technology on canal or river locks.
The threshold of the upper sluice gate is referred to as jam ( middle high German : jam = door threshold ).
function
Like the side gate bearings, the jamb serves as a stop for the closed gate, as a watertight seal and to divert the water pressure of the headwater onto the seal bearing of the lock construction. The distance between the jamb and the surface of the water is called the jam depth. The measure determines the maximum draft of the ships that can pass through the lock.
Among other things, in the Electronic Waterways Information Service ( ELWIS ) of the waterways and shipping administration of the federal government , skippers can find out about the maximum permissible fairways, diving and unloading depths of the respective waterway .
