Serpentine Dam, Western Australia
The Serpentine Dam is a major water supply dam for Perth, Western Australia. The dam is used to store water that is released at a controlled rate to regulate the level in the Serpentine Pipehead Dam reservoir, which in turn feeds water to the metropolitan trunk main network depending on demand. Construction of the dam was completed in 1961. The Serpentine Dam is one of the 15 dams, some of which have since been decommissioned, that have been built in Western Australia since the 1920s, along with the Serpentine Pipehead Dam. It was built as part of the Integrated Water Supply System (IWSS), the largest scheme currently managed by the Water Corporation, which provides water for over two million people in Perth, Mandurah, and other Western Australian regions. Serpentine Dam is connected to the Serpentine Pipehead Dam, which stores water and desalinated water from the Serpentine Dam and other dams nearby for later use. The Serpentine Dam is an important water source because the Per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alcoa
Alcoa Corporation (an acronym for "Aluminum Company of America") is an American industrial corporation. It is the world's eighth-largest producer of aluminum. Alcoa conducts operations in 10 countries. Alcoa is a major producer of primary aluminum, fabricated aluminum, and alumina combined, through its active and growing participation in all major aspects of the industry: technology, mining, refining, smelting, fabricating, and recycling. Alcoa emerged in 1888 as the brainchild of Charles Martin Hall, with the funding of Alfred E. Hunt and Arthur Vining Davis. Alcoa was the first mass producer of aluminum. Before Alcoa's formation, aluminum was difficult to refine and, as a result, was more expensive than silver or gold. In 1886, Hall discovered the Hall–Héroult process, the first inexpensive technique for refining aluminum, drastically reducing the price of aluminum while increasing its availability. Hall approached Hunt and Davis to form a company to bring his process to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution.

Australian Height Datum
The Australian Height Datum was introduced in 1971 as the official vertical datum for Australia, and thereby serves as the Benchmark (surveying), benchmark to which all height measurements are referred. The Australian Height Datum is an amalgamation of decades of spirit levelling work conducted by numerous state and territory authorities across the country, and was corrected to align with the Mean sea-level, mean sea level observations of thirty tide gauges positioned around the entire coastline. While it remains the published vertical datum for all surveying and engineering operations performed throughout Australia, newer technologies have uncovered numerous deficiencies, offsets and distortions within the Australian Height Datum, leading to discussions about defining a new Australian vertical datum. Background The National Mapping Council (pre-1945) Prior to the creation of the Australian Height Datum, Levelling, levelling surveys were carried out by professional surveyor ...

Agricultural
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Archaean Shield
A shield is a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas. These rocks are older than 570 million years and sometimes date back to around 2 to 3.5 billion years. They have been little affected by tectonic events following the end of the Precambrian, and are relatively flat regions where mountain building, faulting, and other tectonic processes are minor, compared with the activity at their margins and between tectonic plates. Shields occur on all continents. Terminology The term shield cannot be used interchangeably with the term craton. However, shield can be used interchangeably with the term basement. The difference is that a craton describes a basement overlain by a sedimentary platform while shield only describes the basement. The term ''shield'', used to describe this type of geographic region, appears in the 1901 English translation of ''Eduard Suess's Face of Earth'' by H. B. C. Sollas, and ...

Goldfields Water Supply Scheme
The Goldfields Water Supply Scheme is a pipeline and dam project that delivers drinking water, potable water from Mundaring Weir in Perth to communities in Western Australia's Eastern Goldfields, particularly Coolgardie, Western Australia, Coolgardie and Kalgoorlie. The project was commissioned in 1896 and completed in 1903. The pipeline continues to operate today, supplying water to over 100,000 people in over 33,000 households as well as mines, farms and other enterprises. Water scarcity During the early 1890s, thousands of settlers had travelled into the barren and dry desert centre of Western Australia seeking gold, but the existing infrastructure for the supply of water was non-existent, and an urgent need arose. Prior to the scheme, water condensers, irregular rain, and Burlong Pool, Western Australia, water trains were part of the range of sources. Railway dams were essential for water to supply locomotives to travel to the goldfields. Origins of the scheme Throughout ...
