- Weir - Wikipedia
Weirs are used to control the flow of water for rivers, outlets of lakes, ponds, and reservoirs, industrial discharge, and drainage control structures There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level

- What is a Weir? - Practical Engineering
Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level
- Types of Weirs and Flow Over Weirs - The Constructor
Weirs are constructed as an obstruction to flow of water These are commonly used to measure the volumetric rate of water flow, prevent flooding and make rivers navigable

Rectangular weirs and triangular or v-notch weirs are often used in water supply, wastewater and sewage systems They consist of a sharp edged plate with a rectangular, triangular or v-notch profile for the water flow
- Weirs: Water Flow Control Structures in Open Channels
Weirs are hydraulic structures that span across open channels such as rivers or streams, creating an obstruction that allows water to flow over the top The fundamental operation of a weir involves increasing the water level upstream, creating a controlled overflow
- Weirs - Civil Engineering Portal
Weirs not sharp crested are classified according to the shape of their cross section, such as broad-crested weirs, triangular weirs, and trapezoidal weirs The channel leading up to a weir is the channel of approach
