A unit of volumetric measure that would cover one acre to a depth of one foot. It is equal to 43,560 cubic feet.
Industry:Energy
The possible adverse incremental consequences that result from the release of water or stored contents due to failure of the dam or misoperation of the dam or appurtenances. Impacts may be for a defined area downstream of a dam from flood waters released through spillways and outlet works of the dam or waters released by partial or complete failure of the dam. There may also be impacts for an area upstream of the dam from effects of backwater flooding or landslides around the reservoir perimeter.
Industry:Energy
The most severe wind that is reasonably possible at a particular reservoir for generating wind setup and run-up. The determination will generally include the results of meteorologic studies that combine wind velocity, duration, direction and seasonal distribution characteristics in realistic manner.
Industry:Energy
The earthquake(s) associated with specific seismotectonic structures, source areas, or provinces that would cause the most severe vibratory ground motion or foundation dislocation capable of being produced at the site under the currently known tectonic framework. It is determined by judgment based on all known regional and local geological and seismological data.
Industry:Energy
An instrument designed to measure water levels or pore water pressures in embankments, foundations, abutments, soil, rock, or concrete. Open system porus-tube, and slotted-pipe piezmoters, or observation wells. Closed,system - Hydraulic twin-tube, pneumatic or vibrating-wire piezometers.
Industry:Energy
A map showing areas that would be affected by flooding from releases from a dam’s reservoir. The flooding may be from either controlled or uncontrolled releases or as a result of a dam failure. A series of maps for a dam could show the incremental areas flooded by larger flood releases.
Industry:Energy
The retention of water or delay of runoff either by planned operation, as in a reservoir, or by temporary filling of overflow areas, as in the progression of a flood wave through a natural stream channel.
Industry:Energy
The integral of the pseudovelocity response spectrum taken over the range of structural vibration periods from 0. 1 to 2. 5 seconds.
Industry:Energy
Also referred to as base width. The maximum thickness or width of the dam measured horizontally between upstream and downstream faces and normal to the axis of the dam, but excluding projections for outlets or other appurtenant structures.
