Note: a subcritical backwater profile starts at an obstruction such as a sluice gate and continues upstream until the water level decreases back to the normal depth. Sluice gates are one of the most common hydraulic structures in controlling flow rate and water level in open channels such as rivers and canals. They also could be used to measure the flow. A water channel containing a sluice gate forms a type of lock to manage the water flow and water level.
