WebIf the discharge remains constant but for a larger gate opening, the upstream depth is smaller and the downstream flow depth is larger. The video shows the underflow beneath a vertical sluice in a 0.25 m wide channel in the Gordon McKay Hydraulics Laboratory of the University of Queensland. WebThe theoretical evaluation was tested against hydraulic lab ... The main purpose of most control gates is to maintain a constant water depth upstream so that orifice-based ofltakes, usually located just upstream of the gates, will deliver water at a near-constant rate regardless of the flow rate in the main canal.
