Canal regulation works are structures that control and regulate the depths, velocities, and discharges of canals. These structures ensure the efficient functioning of a canal irrigation system. 

Canal regulation is the process of distributing water from the main canal to branches. The distribution of flow depends on the water demand of various channels. 
Regulating structures are designed to help maintain water levels in canals by controlling the inflow and outflow of water. By adjusting the gates or barriers in the structures, the flow of water can be regulated to maintain the desired water levels. 
A canal obtains its share of water from the pool behind a barrage through a structure called the canal head regulator. This is also a regulation structure for controlling the amount of water passing into the canal.
