- Company Profile:
A U.S. Department of the Interior agency that oversees water resource management incuding the oversight and operation of numerous diversion, delivery, and storage projects the agency has built throughout the western United States for irrigation, water supply, and attendant hydroelectric power ...
Space-based radio positioning systems that provide 24-hour, three-dimensional position, velocity, and time information to suitably equipped users anywhere on or near the surface of the Earth.
Industry:Engineering
The body of water immediately downstream from a powerplant or pumping plant. A reservoir or pool that regulates fluctuating discharges from a hydroelectric power plant or a pumping plant.
Industry:Engineering
Lines of excavation, backfill, compacted backfill or embankment which are described in the specifications or shown on the drawings which describe or show the limits to which earthwork is paid for.
Industry:Engineering
The lowest-point elevation in the streambed at the axis or centerline crest of the dam prior to construction. This elevation defines the hydraulic height and normally defines the zero for the area-capacity tables.
Industry:Engineering
Portion of spillway between the gate or crest structure and the terminal structure, where open- channel flow conditions will exist. A conduit for conveying free-flowing materials at high velocity to lower elevations.
Industry:Engineering
The minimum value of earth pressure. This condition exists when a soil mass is permitted to yield sufficiently to cause its internal shearing resistance along a potential failure surface to be completely mobilized.
Industry:Engineering
A solid wall built along the top of a dam (upstream and/or downstream edge) used for ornamentation, for safety of vehicles and pedestrians, or to prevent overtopping caused by wave runup.
Industry:Engineering
Any organized system used to ensure that all operations and maintenance activities (e.g., maintenance, inspection, operational testing) at a facility is accomplished and documented.
Industry:Engineering
A material having a low weight per unit volume either as it occurs in its natural state or after compacting it, such as loess with a density of 80 pounds per cubic foot or less.
Industry:Engineering
Angle between the abscissa and the tangent of the curve representing the relationship of shearing resistance to normal stress acting between soil and surface of another material.
