A foundation excavation later to be filled with impervious material so as to limit seepage beneath a dam.
Industry:Energy
The earthquakes for which the structure is designed to resist and remain operational. It reflects the level of earthquake protection desired for operational or economic reasons and may be determined on a probabilistic basis considering the regional and local geology and seismology.
Industry:Energy
A temporary structure enclosing all or part of the construction area that construction can proceed in the dry. A diversion cofferdam diverts a stream into a pipe, channel, tunnel, or other watercourse.
Industry:Energy
A valve for regulating high pressure outlets and ensuring energy dissipation. Inside the valve there is a fixed-cone, pointed upstream, which ensures dispersion of the jet. Outside the valve, a cylindrical sleeve moves downstream to shut off flow by sealing on the periphery of the cone.
Industry:Energy
A gate having wheels or rollers mounted on the end posts of the gate. The wheels bear against rails fixed in side grooves or gate guides.
Industry:Energy

Industry:Energy
To inform appropriate individuals about an emergency condition so they can take appropriate action.
Industry:Energy
An open channel constructed with masonry, concrete or steel of rectangular or U shaped cross section and designed for medium or high velocity flow. Also, a channel in which water is accelerated for purposes of measurement.
Industry:Energy
The compilation of operating criteria, guidelines, and specifications that govern the storage and release function of a reservoir. These are usually expressed in the form of graphs and tabulations, supplemented by concise specifications and are often incorporated in computer programs. In general, they indicate limiting rates of reservoir releases required or allowed during various seasons of the year to meet all functional objectives of the project.
Industry:Energy
The study of the atmospheric and land-surface phases of the hydrologic cycle with emphasis on the interrelationships involved.
