- Company Profile:
The maximum instantaneous discharge that occurs during a flood. It is coincident with the peak of a flood hydrograph.
Industry:Energy
A steeply sloping spillway channel that conveys discharges at super-critical velocities.
Industry:Energy
A plot of the maximum values of acceleration, velocity, and/or displacement response of an infinite series of single-degree-of-freedom systems subjected to a time-history of earthquake ground motion. The maximum response values are expressed as a function of natural period for a given damping.
Industry:Energy
The thickness or width of a dam at the level of the top of dam (excluding corbels or parapets). In general, the term thickness is used for gravity and arch dams, and width is used for other dams.
Industry:Energy
An arch dam that is curved both vertically and horizontally.
Industry:Energy
Any dam constructed of excavated natural materials, such as both earthfill and rockfill dams, or of industrial waste materials, such as a tailings dam.
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. The specific types of storage in reservoirs include: active storage, dead storage, flood surcharge, inactive storage, live storage, reservoir capacity.
Industry:Energy
The vertical distance that would statically result from the velocity of a moving fluid.
Industry:Energy
An identifiable dislocation or distortion within the earth's crust resulting from recent tectonic activity or revealed by seismologic or geologic evidence.
Industry:Energy
A condition whereby soil undergoes continued deformation at a constant low residual stress or with low residual resistance, due to the buildup and maintenance of high pore water pressures, which reduces the effective confining pressure to a very low value. Pore pressure buildup leading to liquefaction may be due either to static or cyclic stress applications and the possibility of its occurrence will depend on the void ratio or relative density of a cohesionless soil and the confining pressure.
