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 ...
A thin-shell radial gate in which the usual skin plate and cross-beam framework are replaced by a hollow shell having an approximate elliptical cross section. This type of gate deviates considerably from the conventional beam and skin-plate design in that the shell itself is relied upon to withstand the beam action.

The point of intersection between the bottom of a slope or the upstream or downstream face of a dam and the natural ground, for example, the upstream or downstream toe of a dam or the downstream toe of a landslide or debris fan. The junction of the face of a dam with the ground surface. For a concrete dam, see heel.
Industry:Engineering
The mutual attraction of soil particles due to molecular and capillary forces in the presence of water. Cohesion is high in clay (especially dry) but of little significance in silt or sand. The ability of a substance to stick to itself and pull itself together. Molecular attraction which holds two particles together.

The Bureau of Land Management, an agency within the U.S. Department of the Interior, administers 264 million acres of America's public lands, located primarily in 12 Western States. The BLM sustains the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations.
Industry:Engineering
A discussion following a facility review examination involving examination team members and interested representatives of the water uses, project, and region. The topics of discussion include the overall condition of the facility, any recommendations made as a result of the examination, and any other pertinent topics.
Industry:Engineering
Shaped, open-channel flow sections that force flow to accelerate. Acceleration is produced by converging the sidewalls, raising the bottom, or a combination of both. An artificial channel, often elevated above ground, used to carry fast flowing water. See long- throated flume, Parshall flume, and short-throated flume.
Industry:Engineering
The first gate in a series of flow controls, remaining open while downstream gates or valves are operating. A gate, usually located between the emergency and regulating gates, used in the closed position to permit servicing of the downstream regulating gate(s) or valve(s) or the downstream conduit. See emergency gate.

Industry:Engineering
The fine-grained portion of soil that is nonplastic or very slightly plastic and that exhibits little or no strength when air dry. Nonplastic soil which passes a No. 200 United States Standard sieve. A soil composed of particles between 1/256 mm and 1/16 mm in diameter. A heavy soil intermediate between clay and sand.
