Aerators are designed to deflect high velocity flow away from the chute surface ( Figure 4 ).
WitrynaOrifice spillways are provided in Run-of-the-river diversion dams where management of sediment along with flood is the main issue. However, accommodating the spillway in a narrow gorge with very high discharges is another aspect. Multistage spillways are provided in such cases to overcome the space constraint.

The beveled edge provides a minimum-friction passageway for the liquid as it spills through the weir’s opening. cleveland school of the arts calendar
