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 waterway used to divert water from its natural course. The term generally applies to a temporary arrangement (e.g., to bypass water around a damsite during construction). Channel is normally used instead of canal when the waterway is short. Occasionally the term is applied to a permanent arrangement (diversion canal, diversion tunnel, diversion aqueducts).
Industry:Engineering
Large logs, planks, cut timbers, steel or concrete beams placed on top of each other with their ends held in guides between walls or piers to close an opening in a dam, conduit, spillway, etc., to the passage of water; the logs are usually handled one at a time. Used to provide a cheaper or more easily handled means of temporary closure than a bulkhead gate.
Industry:Engineering
The rise or movement of water in the interstices of a soil or rock due to capillary forces. The process by which water rises through rock, sediment or soil caused by the cohesion between water molecules and an adhesion between water and other materials that pulls the water upward. A property of surface tension that draws water upwards. See capillary movement.

Located at the U.S. Coast Guard Headquarters in Washington, D.C., the NRC is a 24-hour national communications center and the single point of contact for pollution - incident reporting. It is also the National Response Team's communications center. Immediate reporting is required for reportable quantities of petroleum or hazardous substances 40 CFR 300.125(c).
Industry:Engineering
A gap, rift, hole, or rupture in a dam; providing a break; allowing water stored behind a dam to flow through in an uncontrolled and unplanned manner. An eroded opening through a dam which drains the reservoir. A controlled breach is a constructed opening. An uncontrolled breach is an unintentional opening which allows uncontrolled discharge from the reservoir.
Industry:Engineering
A temporary structure enclosing all or part of the construction area so that construction can proceed in the dry. A diversion cofferdam diverts a river into a pipe, channel or tunnel. A temporary barrier, usually an earthen dike, constructed around a worksite in a reservoir or on a stream, so the worksite can be dewatered or the water level controlled. See dam.
Industry:Engineering
A fracture or fracture zone in the earth's crust along which there has been displacement of the two sides relative to one another or in rock along which the adjacent rock surfaces are differentially displaced. Break in rocks along which movement has occurred. A shear with significant continuity that can be correlated between observation points. See active fault.
Industry:Engineering
Loose, open-structured mass formed in a suspension by the aggregation of minute particles. Clumps of bacteria and particulate impurities that have come together and formed a cluster. Found in flocculation tanks and settling or sedimentation basins. Clumps of impurities removed from water during the purification process; formed when alum is added to impure water.
Industry:Engineering
Used in construction control for cohesionless soils where the in-place density is compared to the minimum and maximum density of the soil from laboratory tests. The ratio of the difference between the void ratio of a cohesionless soil in the loosest state and any given void ratio to the difference between its void ratios in the loosest and in the densest states.
