Gold Creek Dam
The Gold Creek Dam is an earth-fill embankment dam with an un-gated spillway across the Gold Creek that is located in the South East region of Queensland, Australia. The main purpose of the dam is for potable water supply of the Brisbane region. The resultant reservoir is called the Gold Creek Reservoir. Location and features The Gold Creek Dam is located on the edge of Brisbane Forest Park, west of Brisbane, on the Gold Creek, a tributary of Moggill Creek, to augment supplies from the recently completed Enoggera Dam. Unlike Enoggera, the Gold Creek site could supply water to the most elevated parts of the city. The earthfill dam structure is high and long. The dam wall holds back the reservoir when at full capacity. From a catchment area of , the dam creates an unnamed reservoir with an average depth of . The surface area of the wide reservoir is . The uncontrolled un-gated spillway has a discharge capacity of . Initially managed by the Brisbane City Council up unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moggill Creek
Moggill Creek is a creek in Brisbane, the largest city in Queensland, Australia. The creek rises on the Taylor Range and runs in a south-easterly direction from the southern edge of Brisbane Forest Park in Kholo and Pullenvale, flowing through Upper Brookfield, Brookfield and joining the Brisbane River at Kenmore. Before entering the Brisbane River the creek is crossed by Moggill Road and winds through Rafting Ground Reserve. Aboriginal naming of Moggil Creek comes from their description of the large water-lizards that were hunted and eaten in the area. They called these lizards, "magil" (moggill) when they were disturbed and jumped into the water. There are various land uses within the Moggill catchment, including commercial and residential areas, grazing and natural bushland. Moggill Creek is an ephemeral creek: during period of low rain it may not flow. In contrast to other waterways in the Brisbane area, Moggill Creek is considered to be relatively undisturbed. ...

Mountain Bike
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which makes them heavier, more complex and less efficient on smooth surfaces. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight, extra wide handlebars to improve balance and comfort over rough terrain, and wide-ratio gearing optimised for topography and application (e.g., steep climbing or fast descending). Rear suspension is ubiquitous in heavier-duty bikes and now common even in lighter bikes. Dropper posts can be installed to allow the rider to quickly adjust the seat height (an elevated seat position is more effective for pedaling, but poses a hazard in aggressive maneuvers). Mountain bikes are generally specialized for use on mountain trails, single track, fire roads, and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walking Track
A trail, also known as a path or track, is an unpaved lane or small road usually passing through a natural area. In the United Kingdom and the Republic of Ireland, a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to routes along rivers, and sometimes to highways. In the US, the term was historically used for a route into or through wild territory used by explorers and migrants (e.g. the Oregon Trail). In the United States, "trace" is a synonym for trail, as in Natchez Trace. Some trails are dedicated only for walking, cycling, horse riding, snowshoeing or cross-country skiing, but not more than one use; others, as in the case of a bridleway in the UK, are multi-use and can be used by walkers, cyclists and equestrians alike. There are also unpaved trails used by dirt bikes and other off-road vehicles, and in some places, like the Alps, trails are used for moving cattle and other livestock. Usage In Australia ...

Brisbane Transport
Transport for Brisbane, previously called Brisbane Transport'','' is an organisational division of the Brisbane City Council, responsible through its related Council Committee for providing policy and advice to Brisbane City Council, and for delivering various public transport services across the City of Brisbane. The division does this as part of an agreement with TransLink, an agency of the Department of Transport and Main Roads that operates public transport across South East Queensland. History The origins of Transport for Brisbane (formerly, Brisbane Transport) can be traced to August 1885 where the Metropolitan Tramways & Investment Company established a service in Brisbane under franchise from the Queensland Government with 18 horse trams. The tram system remained in private hands until January 1923 when the Queensland government established the Brisbane Tramways Trust, compulsorily acquiring the tram network and supporting infrastructure, then in 1925 creating the Br ...

Water Filtration
A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation, accessible drinking water, public and private aquariums, and the safe use of ponds and swimming pools. Methods of filtration Filters use sieving, adsorption, ion exchanges, biofilms and other processes to remove unwanted substances from water. Unlike a sieve or screen, a filter can potentially remove particles much smaller than the holes through which its water passes, such as Nitrates or germs like ''Cryptosporidium.'' Among the methods of filtration, notable examples are sedimentation, used to separate hard and suspended solids from water and activated charcoal treatment, where the boiled water is poured through a piece of cloth to trap undesired residuals. Additionally, the use of machinery to work on desalinization and purific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentation
Sedimentation is the deposition of sediments. It takes place when particles in suspension settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism. Settling is the falling of suspended particles through the liquid, whereas sedimentation is the final result of the settling process. In geology, sedimentation is the deposition of sediments which results in the formation of sedimentary rock. The term is broadly applied to the entire range of processes that result in the formation of sedimentary rock, from initial erosion through sediment transport and settling to the lithification of the sediments. However, the strict geological definition of sedimentation is the mechanical deposition of sediment particles from an initial suspension in air or water. Sedimentation may pertain to obje ...

Aeration
Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions. Aeration of liquids Methods Aeration of liquids (usually water) is achieved by: * passing air through the liquid by means of the Venturi tube, aeration turbines or compressed air which can be combined with diffuser(s) air stone(s), as well as fine bubble diffusers, coarse bubble diffusers or linear aeration tubing. Ceramics are suitable for this purpose, often involving dispersion of fine air or gas bubbles through the porous ceramic into a liquid. The smaller the bubbles, the more gas is exposed to the liquid increasing the gas transfer efficiency. Diffusers or spargers can also be designed into the system to cause turbulence or mixing if desired. Porous ceramic diffuser ...

Stepped Spillway
A stepped spillway is a spillway with steps on the spillway chute to assist in the dissipation of the kinetic energy of the descending water. This eliminates or reduces the need for an additional energy dissipator, such as a body of water, at the end of the spillway downstream. Historical developments Stepped spillways, consisting of weirs and channels, have been used for over 3,500 years since the first structures were built in Greece and Crete. During Antiquity, the stepped chute design was used for dam spillways, storm waterways, and in the town water supply channels. Most of these early structures were built around the Mediterranean Sea, and the expertise on stepped spillway design was spread successively by the Romans, Muslims and Spaniards. Although the early stepped spillways were built in cut-stone masonry, unlined rock and timber, a wider range of construction materials was introduced during the mid-19th century, including the first concrete stepped spillway of the Gold ...

Geological Survey
A geological survey is the systematic investigation of the geology beneath a given piece of ground for the purpose of creating a geological map or model. Geological surveying employs techniques from the traditional walk-over survey, studying outcrops and landforms, to intrusive methods, such as hand augering and machine-driven boreholes, to the use of geophysical techniques and remote sensing methods, such as aerial photography and satellite imagery. Such surveys may be undertaken by state, province, or national geological survey organizations to maintain the geological inventory and advance the knowledge of geosciences for the benefit of the nation. A geological survey map typically superimposes the surveyed extent and boundaries of geological units on a topographic map, together with information at points (such as measurements of orientation of bedding planes) and lines (such as the intersection of faults with the land surface). The maps and reports created by geological surv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
