The structure being talked about is known as "Head Work". It is a hydraulic structure which supplies water to the off taking canal. Diversion head work provides an obstruction across a river, so that the water level is raised and water is diverted to the channel at required level. 
The main purposes of the head work is :
1. It raises the water level in the river.
2. It regulates the water level into the canal
3. It also controls the entry of slit into canal
4. A head work can also store water for small periods of time.
5. It reduces fluctuations in the level of supply in river.
