Where is the control weir of a side channel spillway located?

The control weir of a side channel spillway (Fig. 11.10) is located alongside and approximately parallel to the upstream portion of the spillway discharge channel which itself may be either an open channel or a closed conduit or an inclined tunnel.

What is the lower part of a spillway?

The lower part of the spillway surface is tangential to the upper curve and supports the falling sheet of water. The downstream end of the spillway is in the form of a reverse curve, which turns the flow onto the apron of a stilling basin or into the spillway discharge channel.

When is a hydraulic jump required for a spillway?

When tail water depth is sufficient, a hydraulic jump would form when the water jet falls upon a flat apron. Free over-fall spillways are restricted only to situations where the hydraulic drop from reservoir level to tail water level is less than about six metres. Type # 2. Ogee (Overflow) Spillway:

What is the discharge coefficient of a side channel spillway?

If the height of the vertical face of the corbel is kept more than 0.3 times the head over the crest, the discharge coefficient of the spillway will be practically the same as if the vertical face of the corbel extended for the full height of the spillway. Type # 3. Side Channel Spillway:

How do Obermeyer spillway gates benefit low head hydropower plants?

Low head hydropower plants benefit both from the greater head provided by Obermeyer gates and from the greater turbine flow rate resulting from the greater head provided. Significant increases in annual generation may be achieved by the installation of Obermeyer spillway gates at low head hydropower plants.
