ABSTRACT:
A flexible membrane-type rising and falling weir is anchored at the curved crest of a concrete structure in a body of water. A drain discharge pipe has an opening positioned at the lowest portion of the interior of the envelope to provide complete discharge of water accumulated so that the weir deflates completely to permit smooth flow of water over it.
