What is the difference between headworks and barrage?
As nouns the difference between barrage and headworks is that barrage is barrier while headworks is any structure at the head or diversion point of a waterway it is smaller than a barrage and is used to divert water from a river into a canal or from a large canal into a smaller canal.
What is headwork and its types?
Canal Headworks are classified to: 1. Diversion Headworks: A weir or a barrage is constructed across a river to raise water level and to divert water to a canal is known as a diversion headwork. 2. Storage Headworks: A dam is constructed across a river valley to form a storage reservoir is known as a storage headwork.
What is weir proper?
It is a barrier constructed across the river. It aims to raise the water level in order to feed the canal. Under-sluices: The under sluices are the openings provided at the base of the weir or barrage.
What is the difference between barrage and reservoir?
Dam and reservoirs are constructed across a river valley for water storage and to hold back the water flow. Major difference between a dam and barrage is that, Dam built for water storage the lake is called as reservoirs and barrage build to divert the river water.
What is the main purpose of barrage?
A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems.

What is canal regulator?
Canal Regulator. It is a structure at the head of canal taking off from a reservoir may consists of number of spans separated by piers and operated by gates. Regulators are normally aligned at 90° to the weir. Up to 10″ are considered preferable for smooth entry into canal. These are used for diversion of flow.
What is the purpose of barrage?
Why are barrages needed?
These gates are opened and closed to directly control the amount of water that passes through it. Unlike a dam, which will raise waters nearly to its height, a barrage will only raise the water level by a few feet. This is also useful for navigation, because a barrage can increase the depth of a river by a few feet.
