Flood flows expected at a point on the river system below a dam at the same time a flood inflow occurs above the dam.
Industry:Energy
Measure external vertical and horizontal movement on the surface. These instrumentations include triangulation, trilateration, global positioning system (GPS), photogrammetric, and collimation.
Industry:Energy
Structural members of timber, concrete, or steel placed in channels or on the crest of a spillway to raise the reservoir water level but intended to be quickly removed, tripped, or fail in the event of a flood.
Industry:Energy
A device fitted to a pipeline or orifice in which the closure member is either rotated or moved transversely or longitudinally in the waterway so as to control or stop the flow.
Industry:Energy
Filling, with cement grout, any voids existing at the contact of two zones of different materials, i.e., between a concrete tunnel lining and the surrounding rock.
Industry:Energy
A flood that has 1 chance in 100 of being equaled or exceeded during any year.
Industry:Energy
The variation in water level, up or down, as a result of project operation.
Industry:Energy
Earthquake time history records developed from mathematical models that use white noise, filtered white noise, and stationary and non-stationary filtered white noise, or theoretical seismic source models of failure in the fault zone. (White noise is random energy containing all frequency components in equal proportions. Stationary white noise is random energy with statistical characteristics that do not vary with time. )
Industry:Energy
A vertical or inclined layer of pervious material in an embankment to facilitate and control drainage of the embankment fill.
