Overflow threshold

from Wikipedia, the free encyclopedia
Example of an overflow threshold at the outlet of the Fuhse Canal into the Oker in the Braunschweig South Sea area

The overflow threshold limits the highest possible water level and the total storage space in natural or artificially created water basins, such as a lake , a dam , a canal , a swimming pool , a cistern , a sewage treatment plant or the like. In contrast to other technical facilities such as a weir , it is not adjustable in height, but is fixed in height by earth walls or masonry.
