Weirs and barrages are both river structures that have been used in India since the mid-19th century. 

Weirs and barrages differ in the following ways:
Weirs: These dam-like structures are built across rivers or streams to control water flow. They are usually made of concrete, masonry, wood, rocks, gravel, or boulders. Weirs raise water levels by using a raised crest, and are less expensive than barrages. However, they offer less control over water levels, are more likely to silt up, and are constructed from earth, concrete, or masonry.
Barrages: These weir-like structures have large gates that can be opened or closed to control the amount of water that flows through them. Barrages are made of concrete and have gates supported by pillars. They control discharge and increase water level by using sluice gates or regulators. When designing a barrage, it is important to consider surface flow and overflow, as well as safety against subsoil flow.
