Verlaat (hydraulic engineering)

The Verlaat at the Camper bridge in Berne separating the flow drive of the Berne (from the right) in the lower coils (to the left, to Hunte ) from the "top" portions of the coils, which now by the Motzer channel in the Weser expire

Verlaat is a hydraulic engineering term and comes from the Dutch language.

Basic meaning

It is a structure that regulates the inflow to a particularly low-lying area. A verlaat is intended to prevent the water from flowing from higher areas into lower areas during heavy rainfall. In contrast, in the Netherlands the term is used for locks .

A verlaat is a blocking gate in a water network that, unlike a weir, should not be overflowed and, unlike a sewer, is not opened periodically .

Connotation

A verlaat can also be built into a sewer basin . It is used to fill part of the water with tidal water without it penetrating too far into the interior. So the nearby behind the Siel part can the lows during periods of low rainfall, so if the water is not sufficiently flushed with abzuleitendem the upper hand, while the flood filled and during low tide emptied again to silt deposits from the sewer to flush. Such verlaate are, as it were, a second sluice behind the actual sluice, so they must be easy to open and close.

Place names

The word is found in place names except in the Netherlands only very close to the Dutch border ( e.g. Ditzumerverlaat ), so that the Dutch meaning of the word comes into question here. In addition, the word is common as a street name near the buildings, such as the "Rahster Verlaat" near the Raher Schleuse .
