Cathaleen's Fall Hydroelectric Power Station
Cathaleen's Fall hydroelectric power station is a hydroelectric plant located on the River Erne at Ballyshannon in County Donegal, Ireland. It is owned and operated by the ESB Group. The plant is also known as Ballyshannon. Construction Plans to dam the Erne for power had been considered in the 1920s, but it was not until 1946 that construction of dams started at two locations on the river between Belleek and Ballyshannon. Cathaleen's Fall was the larger and more downriver of the two. Construction of the reinforced concrete gravity dam started in 1946 and was complete in 1955. The dam is long and high. It has three spillway gates, each long. Concrete is used throughout the construction and the generating station is constructed in the modernist style with curved cantilevered stairs and a glass roofed atrium. Generating capacity The plant consists of two Kaplan turbines each rated at on a head of water. The first turbine was commissioned in 1951 and the second in 195 ...

Hydraulic Head
Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth. Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a ''hydraulic gradient'' between two or more points. "Head" in fluid dynamics In fluid dynamics, ''head'' is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Juvenile Fish
Fish go through various life stages between fertilization and adulthood. The life of a fish start as spawned eggs which hatch into immotile larvae. These larval hatchlings are not yet capable of feeding themselves and carry a yolk sac which provides stored nutrition. Before the yolk sac completely disappears, the young fish must mature enough to be able to forage independently. When they have developed to the point where they are capable of feeding by themselves, the fish are called fry. When, in addition, they have developed scales and working fins, the transition to a juvenile fish is complete and it is called a fingerling, so called as they are typically about the size of human fingers. The juvenile stage lasts until the fish is fully grown, sexually mature and interacting with other adult fish. Growth stages Ichthyoplankton ''(planktonic or drifting fish)'' are the eggs and larvae of fish. They are usually found in the sunlit zone of the water column, less than 200 ...

Cantilevered Stairs
Cantilevered stairs, or floating stairs, are a type of staircase. A cantilever is a beam, which is anchored at only one end. Thus cantilevered stairs have a "floating" appearance, and they may be composed of different materials, such as wood, glass, stone, or stainless steel Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's r ....
