weir
A weir is characterized by its intentional permeability, allowing water to spill over its crest rather than blocking it entirely like a traditional dam. It is primarily used for hydraulic control, such as maintaining a constant upstream water level or measuring the rate of flow in a stream.
In industrial and environmental engineering, the term extends to specialized barriers in treatment plants. These structures are designed to skim surface scum or debris from the water, utilizing the physics of overflow to separate solids from liquids.
