Timeline Of The Greater Victoria Water System
The water supply system for Victoria, British Columbia, Canada, now operated by the Capital Regional District (CRD), served in 2010 over 330,000 people with clean drinking water from a catchment area of centered on its main reservoir at Sooke Lake.Capital Regional District: Facts and Figures: Greater Victoria Water Supply System, May 2009. hxtp://www.crd.bc.ca/water/documents/factsfigs_2009.pdf The CRD’s ownership and complete control of its entire watershed assures its customers of a supply that is secure in both quantity and quality. The main reservoir and its subsidiary reservoirs are estimated to contain 93 billion litres of water, enough to meet the needs of its customers for two years without any rainfall. The history of this remarkable system is sketched below. Beginnings (1842–1843) In 1842 Sir James Douglas led an expedition from Fort Vancouver on the Columbia River to find a suitable location for a Hudson’s Bay trading post on southern Vancouver Island. He exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of ...

Siphon 04
A siphon (from grc, σίφων, síphōn, "pipe, tube", also spelled nonetymologically syphon) is any of a wide variety of devices that involve the flow of liquids through tubes. In a narrower sense, the word refers particularly to a tube in an inverted "U" shape, which causes a liquid to flow upward, above the surface of a reservoir, with no pump, but powered by the fall of the liquid as it flows down the tube under the pull of gravity, then discharging at a level lower than the surface of the reservoir from which it came. There are two leading theories about how siphons cause liquid to flow uphill, against gravity, without being pumped, and powered only by gravity. The traditional theory for centuries was that gravity pulling the liquid down on the exit side of the siphon resulted in reduced pressure at the top of the siphon. Then atmospheric pressure was able to push the liquid from the upper reservoir, up into the reduced pressure at the top of the siphon, like in a baromet ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the ''drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowline On Trestle
Linear scheduling method (LSM) is a graphical scheduling method focusing on continuous resource utilization in repetitive activities. Application LSM is used mainly in the construction industry to schedule resources in repetitive activities commonly found in highway, pipeline, high-rise building and rail construction projects. These projects are called repetitive or linear projects. The main advantages of LSM over critical path method (CPM) is its underlying idea of keeping resources continuously at work. In other words, it schedules activities in such a way that: # resource utilization is maximized; # interruption in on-going process is minimized, including hiring-and-firing; and # the effect of the learning curve phenomenon is maximized Alternative names According to, specific names for the linear scheduling method have been adopted, such as: *Location-based scheduling (the preferred term in the book) *Harmonograms *Line-of-balance *Flowline or flow line *Repetitive sche ...

Goldstream Lake
The Goldstream River ( Saanich: sʔə́ləq̕ʷtəɬ) is a river northwest of Victoria on southern Vancouver Island, British Columbia, Canada . The river's name derives from a small gold rush in its basin during the 1860s, and was originally Gold Stream. Course The Goldstream River begins at the outlet of Butchart Lake, the first of three reservoirs along the upper reaches of the Goldstream which are within the Greater Victoria Watershed Area. Shortly after exiting Butchart Lake it flows into Lubbe Lake. Shortly after exiting Lubbe Lake the river enters the final and largest of the three lakes, Goldstream Lake. After exiting Goldstream Lake, the river flows southeast until it turns north and enters Goldstream Provincial Park. Just before entering the park, the river receives its first major tributary, Waugh Creek. About halfway through the park, the river tumbles over Goldstream Falls. After the falls it continues north, receiving its final major tributary, Niagara Creek, j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thetis Lake
Thetis Lake is a name that refers to two freshwater lakes (Upper and Lower Thetis) connected by a narrow culvert in the Thetis Lake Regional Park outside Victoria, British Columbia, about from the city centre. It was established as Canada's first nature sanctuary in 1958. - CRD The park was named for the frigate HMS ''Thetis'', which had been assigned to Esquimalt as part of the |
Beaver Lake (British Columbia)
Elk Lake is a large lake located in Elk/Beaver Lake Regional Park in Saanich, British Columbia. Elk Lake and Beaver Lake are actually one lake as a shallow channel connects them. Elk/Beaver lake was known as the "Freshwater Playground of Victoria" in its heyday, the 1930s and 1940s. However, with the completion of the Pat Bay highway in the 1950s, focus turned to environmentalism Environmentalism or environmental rights is a broad Philosophy of life, philosophy, ideology, and social movement regarding concerns for environmental protection and improvement of the health of the environment (biophysical), environment, par ..., and measures were taken to start restoring the park to its natural state and protecting it. In 1966 Elk/Beaver lake became a regional park.
