Blue Mountains Dams
The Blue Mountains Dams are a series of six dams in the Blue Mountains which supply water to the Blue Mountains and Sydney, Australia. The Dams are managed by the WaterNSW. Water in this scheme may be supplemented from the Fish River Scheme. Cascade Dams There are three dams built on the Cascade Creek, near Katoomba, known as Cascade numbers 1, 2 and 3. The Middle Dam was first, completed in 1908. It is tall; long; and holds . The Lower Cascade Dam is an earthfill embankment dam with a central concrete core which was completed in 1926. It is high; long; and holds . The Upper Cascade Dam is another earthfill embankment dam, built in 1938. It is high; long; and it holds . Middle Cascade Dam is a "Darley-Wade" dam named after the series of dams designed by L.A.B Wade, a prominent dam engineer of the era and CW Darley who designed the first constant radius thin-arch dam in Australia (Lithgow 1). It was originally constructed in 1908 as a buttress section before being rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Mountain Dam
Blue Mountain Lake is a reservoir in Arkansas, United States. A U.S. Army Corps of Engineers Lake on the Petit Jean River in west central Arkansas, Blue Mountain Lake has approximately 50 miles of shoreline, located between Mount Magazine and the Ouachita Mountains just west of Havana, Arkansas. Blue Mountain Dam was built in 1947 as a 115-foot-high, 2800-foot-long earthen structure, creating a reservoir with a surface area of about 4.5 square miles, about 50 miles of shoreline, and a maximum capacity of 258,000 acre-feet.

Blue Mountains (New South Wales)
The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about west of centre of the state capital, close to Penrith on the outskirts of Greater Sydney region. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. As defined in 1970, the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin. The ''Blue Mountains Range'' comprises a range of mountains, plateau escarpments extending off the Great Dividing Range about northwest of Wolgan Gap in a generally southeasterly direction for about , terminating at . For about two-thirds of its len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medlow Dam
Medlow Dam is a heritage-listed major gated concrete-walled arch dam across the Adams Creek in the Blue Mountains region, located at Beauchamp Road, Medlow Bath in the City of Blue Mountains local government area of New South Wales, Australia.

Geography Of Sydney
The geography of Sydney is characterised by its coastal location on a basin bordered by the Pacific Ocean to the east, the Blue Mountains to the west, the Hawkesbury River to the north and the Woronora Plateau to the south. Sydney lies on a submergent coastline on the east coast of New South Wales, where the ocean level has risen to flood deep river valleys (rias) carved in the Sydney sandstone. Port Jackson, better known as Sydney Harbour, is one such ria. The Sydney area lies on Triassic shales and sandstones. The region mostly consists of low rolling hills and wide valleys in a rain shadow area that is shielded by the Great Dividing Range. Sydney sprawls over two major regions: the Cumberland Plain, a relatively flat region lying to the west of Sydney Harbour, and the Hornsby Plateau, a plateau north of the Harbour rising to 200 metres and dissected by steep valleys. Sydney's native plant species are predominantly eucalyptus trees, and its soils are usually red and yellow i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Dams
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Dams In New South Wales
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, tap water, human consumption, Industrial water, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as Dike (construction), dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam (Jordan), Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.
