Emergency spillway definition

Emergency spillway means the spillway capable of passing the spillway design storm with the principal and/or auxiliary spillway blocked.

Emergency spillway means a spillway designed to safely pass the inflow design flood routed through the reservoir. If the flow is controlled by gates, it is a con- trolled spillway. If the flow is not controlled by gates, it is an uncontrolled spillway.

Emergency spillway means a discharge system designed to operate at an elevation above the principal spill way to safely convey discharges that exceed the principal spill way's capacity without jeopardizing the safety of the dam.

Examples of Emergency spillway in a sentence

• Emergency spillway armor must extend up the sides of the spillway, and continue at full width to a minimum of 10 feet past the toe of slope.

• Emergency spillway shall be located in existing soils when feasible and armored with riprap or other approved erosion protection extending to the toe of the embankment.

• Emergency spillway armor must extend up the sides of the spillway, and continue at full width to a minimum of ten (10) feet past the toe of slope.

• Emergency spillway grades and allowable velocities shall be approved by the regulatory authority.(10) The minimum elevation at thetop of the settled embankment shall be1.0 foot above the water surface in the pond with the emergency spillway flowing at design depth.

The lower elevation spillway that spills first is referred to as the principle spillway. The higher elevation spillway is referred to as the emergency spillway;
