A stream; especially, a passage channel, or conduit for the water that drives a mill wheel; or an artifical channel of water for hydraulic or placer mining; also, a chute for conveying logs or lumber down a declivity.
An inclined channel of wood or stone used to convey water for long distances. A narrow gorge or ravine can also be used for the same purpose and is sometimes referred to as a flume. Many miles of flumes were built at great expense to bring in water to a hydraulic mining site.
area on a river where the water current accelerates. Usually between large rocks and boulders, or in regions where a riverâ€™s width is lessened. Here, the more aggressive mid-to-large size fish gather to feast on the insects and other small prey that flows downstream.
An artificial channel with clearly specified shape and dimensions which may be used for the measurement of flow. A standing-wave flume, for instance, contains a constriction which causes the flow to change from sub-critical* to super- critical* and in which the measurement of upstream water level (alone) allows the discharge to be computed.
An inclined waterway, most often a channel dug in the hillside to transport water to hydraulic mining camps. Simply described, they are similar to a long series of sluices, and in fact, the name flume was once synonymous with sluice.
A type of in-channel measuring device of known cross-sectional area in a ditch or river. Also used to describe the facility used to bridge flowing water across another channel, depression, or other rough terrain.
1. In open channel flow, a manufactured conduit (usually rectangular in shape) with a portion having a constricted cross section, which may be used to control and measure streamflow. 2. In geomorphology, a narrow, steep-sided valley. 3. In hydraulics, a channel used for studying the flow of fluids under gravity. The fluid is pumped from a sump to a stilling tank that acts as a reservoir from which the fluid is discharged down the flume at varying speeds. The motion is viewed from above or through glass sides.
A flume is a waterwork with open water table, that leads water from a diversion dam or weir completely aside a natural flow, often an elevated box structure (typically wood) that follows the natural contours of the land. These have been extensively used in hydraulic mining, for the transportation of logs in the logging industry, electric power generation and to power various mill operations by the use of a waterwheel.
Flume is a component pipeline engine. It allows you to chain multiple workers into a pipeline mechanism. The intention of Flume is that each of the workers should provide access to a different type of technology. For example, a pipeline could consist of a Jython script worker followed by a BeanShell script worker followed by an XSLT worker.
