81-695: 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 . The Gold Creek Dam is located on the edge of Brisbane Forest Park , 14 kilometres (8.7 mi) west of Brisbane, on

162-509: A catchment area of 10.5 square kilometres (4.1 sq mi), the dam creates an unnamed reservoir with an average depth of 26 metres (85 ft). The surface area of the 1.2-metre (3 ft 11 in) wide reservoir is 2.46 hectares (6.1 acres). The uncontrolled un-gated spillway has a discharge capacity of 132 cubic metres per second (4,700 cu ft/s). Initially managed by the Brisbane City Council up until 2008,

243-594: A path or track , is an unpaved lane or a small paved road not intended for usage by motorized vehicles , usually passing through a natural area . In the United Kingdom and Ireland , a path or footpath is the preferred term for a pedestrian or hiking trail. The term is also applied in North America to accompanying routes along rivers, and sometimes to highways. In the US, the term was historically used for

324-464: 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 with wide valleys. They can be built on hard rock or softer soils. For a rock-fill dam, rock-fill is blasted using explosives to break the rock. Additionally, the rock pieces may need to be crushed into smaller grades to get

405-629: A boat, often a barge . They can be paved or unpaved and are popular with cyclists and walkers; some are suitable for equestrians. Equestrians have legal access to all towpaths in Scotland, and there is a campaign for similar rights in England and Wales. In snowy winters in the USA they are popular with cross-country skiers and snowmobile users. Most canals were owned by private companies in Britain, and

486-542: A bridleway must give way to other users on foot or horseback. The seawall in Stanley Park , Vancouver, British Columbia , Canada is popular for walking, running, cycling, and inline skating . There are two paths, one for skaters and cyclists and the other for pedestrians. The lane for cyclists and skaters goes one-way in a counterclockwise loop. Foreshoreway (also oceanway ) is a term used in Australia for

567-509: A general acceptance that towpaths are open to everyone, and not just boat users. The concept of free access to towpaths is enshrined in the legislation which transferred responsibility for the English and Welsh canals from British Waterways to the Canal & River Trust in 2012. Not all towpaths are suitable for use by cyclists, but where they are, and the canal is owned by British Waterways,

648-546: A gravel or dirt surface suitable for walking, mountain bikes and horses. In the USA the 42 mi (68 km) Cheshire Rail Trail , in New Hampshire , can be used by hikers, horseback riders, snowmobilers, cross-country skiers, cyclists, and even dogsledders . In Canada, following the abandonment of the Prince Edward Island Railway in 1989, the government of Prince Edward Island purchased

729-577: A legally protected right to travel. National parks , nature preserves , conservation areas and other protected wilderness areas may have trails that are restricted to pedestrians. Footpaths can be connected to form a long-distance trail or way, which can be used by both day hikers and backpackers . Some trails are over 1,000 miles (1,600 km) long. In the US and Canada, where urban sprawl has reached rural communities, developers and local leaders are currently striving to make their communities more conducive to non-motorized transportation through

810-598: A mix of challenging terrain, singletrack , smooth fireroads , and even paved paths. Trails with an easy or moderate technical complexity are generally deemed cross-country trails, while trails difficult even to experienced riders are more often dubbed all-mountain , freeride , or downhill. Downhilling is popular at ski resorts like Mammoth Mountain in California, or Whistler Blackcomb in British Columbia, where ski lifts are used to get bikes and riders to

891-491: A particular use is accompanied by prohibitions against that use on other trails within the trail system. Trail segregation may be supported by signage, markings, trail design and construction (especially the selection of tread materials), and by separation between parallel treads. Separation may be achieved by "natural" barriers including distance, ditching, banking, grading, and vegetation, and by "artificial" barriers including fencing, curbing, and walls. Bicycle trails encompass

972-607: A permit is required. There is no charge for a permit, but it acts as an opportunity to inform cyclists about safe and unsafe areas to cycle. Some areas including London are exempt from this policy, but are covered instead by the London Towpath Code of Conduct and cyclists must have a bell, which they ring twice when approaching pedestrians. Parts of some towpaths have been incorporated into the National Cycle Network, and in most cases this has resulted in

1053-534: A proliferation of mountain bike trails in many countries. Often these will be grouped to form larger complexes, known as trail centers. In the early years of the 20th century, the term auto trail was used for a marked highway route, and trail is now used to designate routes, including highway routes, designated for tourist interest like the Cabot Trail , Nova Scotia, Canada and the Quilt Trails in

1134-615: A rock-fill dam is New Melones Dam in California or the Fierza Dam in Albania . A core that is growing in popularity is asphalt concrete . The majority of such dams are built with rock and/or gravel as the primary fill. Almost 100 dams of this design have now been built worldwide since the first such dam was completed in 1962. All asphalt-concrete core dams built so far have an excellent performance record. The type of asphalt used

1215-562: A rock-fill dam. The frozen-core dam is a temporary earth dam occasionally used in high latitudes by circulating a coolant through pipes inside the dam to maintain a watertight region of permafrost within it. Tarbela Dam is a large dam on the Indus River in Pakistan , about 50 km (31 mi) northwest of Islamabad . Its height of 485 ft (148 m) above the river bed and 95 sq mi (250 km ) reservoir make it

1296-905: 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 shared-use and can be used by pedestrians, cyclists and equestrians alike. Although most trails are for low-traffic, non-motorized usage, there are also unpaved trails used by dirt bikes , quad bikes and other off-road vehicles , usually for extreme sports and rally races . In some places, like

1377-403: A shell of locally plentiful material with a watertight clay core. Modern zoned-earth embankments employ filter and drain zones to collect and remove seep water and preserve the integrity of the downstream shell zone. An outdated method of zoned earth dam construction used a hydraulic fill to produce a watertight core. Rolled-earth dams may also employ a watertight facing or core in the manner of

1458-472: A trail is also called a track or piste. Recreational cross-country skiing is also called touring, especially in Europe. Some skiers stay out for extended periods using tents and equipment similar to bushwalkers and hikers, whereas others take shorter trips from ski resorts on maintained trails. In some countries, organizations maintain a network of huts for use by cross-country skiers in wintertime. For example,

1539-479: A type of greenway that provides a public right-of-way along the edge of the sea open to both walkers and cyclists. A forest road is a type of rudimentary access road, built mainly for the forest industry . In some cases they are used for backcountry recreation access. There is open access to most Forestry Commission roads and land in Great Britain for walkers, cyclists and horse riders and, since

1620-498: A wide variety of trail types, including shared-use paths used for commuting, off-road cross-country trails and downhill mountain bike trails. The number of off-road cycle trails has increased significantly, along with the popularity of mountain bikes . Off-road bicycle trails are generally function-specific and most commonly waymarked along their route. They may take the form of single routes or form part of larger complexes, known as trail centers. Off-road trails often incorporate

1701-545: Is a Walloon initiative aimed at creating a network of route itineraries reserved for pedestrians, cyclists, horse riders and people with reduced mobility. The 1,350 km (840 mi) network makes use of towpaths on river banks and disused railway or vicinal tramway lines ( narrow-gauge tramways). Old railway lines have been leased by the Walloon Government for 99 years using emphyteutic lease contracts. Where necessary, new paths are created to link parts of

1782-423: Is a sunken path or lane , i.e., a road or track that is significantly lower than the land on either side, not formed by the (recent) engineering of a road cutting but possibly of much greater age. Various mechanisms have been proposed for how holloways may have been formed, including erosion by water or traffic; the digging of embankments to assist with the herding of livestock; and the digging of double banks to mark

1863-548: Is a viscoelastic - plastic material that can adjust to the movements and deformations imposed on the embankment as a whole, and to settlement of the foundation. The flexible properties of the asphalt make such dams especially suited to earthquake regions. For the Moglicë Hydro Power Plant in Albania the Norwegian power company Statkraft built an asphalt-core rock-fill dam. Upon completion in 2018

1944-432: Is a type of thoroughfare that is intended for use only by pedestrians either within an urban area or through the countryside. An urban footpath is usually called an alley or lane and often paved (see also: sidewalk and pavement ). Other public rights of way , such as bridleways , byways , towpaths, and green lanes are also used by pedestrians. In England and Wales, there are rights of way on which pedestrians have

2025-486: Is at hand, transport is minimized, leading to cost savings during construction. Rock-fill dams are resistant to damage from earthquakes . However, inadequate quality control during construction can lead to poor compaction and sand in the embankment which can lead to liquefaction of the rock-fill during an earthquake. Liquefaction potential can be reduced by keeping susceptible material from being saturated, and by providing adequate compaction during construction. An example of

2106-559: Is common with rail trails . Shared use may also refer to alternate day arrangements, whereby two uses are segregated by being permitted every other day. This is increasingly common on long-distance trails shared by equestrians and mountain bike users; these two user communities have similar trail requirements but may experience difficult encounters with each other on the trail. The Trans Canada Trail can be used by cyclists, hikers, horseback riders, and walkers, as well as cross-country skiers , snowmobilers and snowshoers in winter. In

2187-434: Is generally a narrow winding track clinging to steep hillside with some climb. The next 1.5 kilometres (0.93 mi) (approx) appears to be formed by repeated use of a quad bike and is generally wider and flatter. The next 1.5 kilometres (0.93 mi) (approx) return path along the eastern side of the reservoir is narrow and fairly rugged, climbing and dropping repeatedly. The final 1 kilometre (0.62 mi) (approx) back to

2268-481: Is increasingly common and diverse. For example, bike trails are used not only on roads open to motor vehicles but also in trail systems open to other trail users. Some trails are segregated for use by both equestrians and mountain bikes or by equestrians or mountain bikes alone. Designated "wilderness area" trails may be segregated for non-wheeled use permitting backpacking and horses but not permitting mountain bikes and motorized vehicles. Often, trail segregation for

2349-548: Is very overgrown and little used and its route can no longer be seen at the northernmost point. This makes circumnavigation of the dam very difficult. Walking and riding tracks which travel deep into Brisbane Forest Park also begin here. Gold Creek Reservoir is home to the Pinnacles Classic, a small trail running event held in mid-April which uses a hilly, roughly rectangular 18-kilometre (11 mi) course which utilises Gold Creek Boundary Break, South Boundary Road and

2430-435: Is winding and somewhat narrow but generally flat and suitable for cycling or walking. A steep walking track gives access to the top of the dam at the eastern end; alternatively a gentle vehicle track gives access to the western end of the top of the dam. At the foot of the dam is a public toilet and an information board. The board shows a map of the dam and the walking track . On water activities are not permitted, even though

2511-558: The Alps , trails are used by alpine agrarian communities for moving cattle and other livestock . In Australia, the term track can be used interchangeably with trail or walk, and can refer to anything from a dirt road to an unpaved pedestrian path . In New Zealand, the terms track or walkway are used almost exclusively except when referring to cross-country skiing : "walkways vary enormously in nature, from short urban strolls, to moderate coastal locations, to challenging tramps [hikes] in

2592-525: The California Gold Rush in the 1860s when miners constructed rock-fill timber-face dams for sluice operations . The timber was later replaced by concrete as the design was applied to irrigation and power schemes. As CFRD designs grew in height during the 1960s, the fill was compacted and the slab's horizontal and vertical joints were replaced with improved vertical joints. In the last few decades, design has become popular. The tallest CFRD in

2673-805: The Intermodal Surface Transportation Efficiency Act of 1991 mandates that states must use a minimum of 30 percent of these funds for motorized trail uses. Some members of the US government and environmental organizations, including the Sierra Club and The Wilderness Society . have criticized off-road vehicle use on public land . They have noted several consequences of illegal ORV use such as pollution, trail damage, erosion , land degradation , possible species extinction , and habitat destruction which can leave hiking trails impassable. ORV proponents argue legal use taking place under planned access along with

2754-506: The Norwegian Mountain Touring Association maintains over 400 huts stretching across hundreds of kilometres of trails hikers use in the summer and skiers use in the winter. Horse riding and other equestrian uses of trails continue to be a popular activity for many trail users. Horses can usually negotiate much the same grades as hikers, but not always, although they can more easily clear obstacles in

2835-678: The Persian Empire , existed before the Christian era and covered great distances. The Post Track , a prehistoric causeway in the valley of the River Brue in the Somerset Levels , England, is one of the oldest known constructed trackways and dates from around 3838 BC. The idea of following a path or track for exercise or pleasure developed during the 18th century in Europe and arose because of changing attitudes to

2916-485: The Usoi landslide dam leaks 35-80 cubic meters per second. Sufficiently fast seepage can dislodge a dam's component particles, which results in faster seepage, which turns into a runaway feedback loop that can destroy the dam in a piping-type failure. Seepage monitoring is therefore an essential safety consideration. gn and Construction in the U.S. Bureau of Reclamation Walking track A trail , also known as

2997-450: The "Grand Concourse", is an integrated walkway system that has over 160 km (99 mi) of walkways, which link every major park, river, pond and green space in six municipalities. A motorized trail is a trail intended for off-road vehicles for example 4×4 cars, dirt bikes, All-terrain vehicles (ATV). Motorized trail use remains very popular with some people, particularly in the US. The Recreational Trails Program defined as part of

3078-543: The 320 m long, 150 m high and 460 m wide dam is anticipated to be the world's highest of its kind. A concrete-face rock-fill dam (CFRD) is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure. In addition, the CFRD design is flexible for topography, faster to construct and less costly than earth-fill dams. The CFRD concept originated during

3159-506: The Board of Waterworks. The construction tender was won by Ross and Dunbar based on designs developed by J. B. Henderson. The connection to the growing Brisbane population was by a single 16 inches (41 cm), cast-iron, mains pipe that was 20 kilometres (12 mi) in length. Originally an unlined chute , the dam spillway was damaged during floods in early 1890. It was replaced by an un-reinforced concrete stepped spillway  –

3240-631: The Countryside Bill of 1968, it has become the largest provider of outdoor recreation in Britain. The commission works with associations involved in rambling , cycling, mountain biking and horse riding to promote the use of its land for recreation. The trails open to the public are not just forest roads. A notable example of the commission's promotion of outdoor activity is the 7stanes project in Scotland, where seven purpose built areas of mountain bike trails have been laid, including facilities for disabled cyclists. A Holloway (also hollow way)

3321-651: The Dutch LF-Routes , the German D-Routes , and the British National Cycle Network , and existing general-purpose roads, together with new stretches of cycle routes to connect them. Off-road cycling can cause soil erosion and habitat destruction if not carried out on established trails. This is true when trails are wet, though overall, cycling may not have more of an impact as other trail users. In cross-country skiing,

3402-477: The Gold Creek Trail, starting and finishing at the gate at Gold Creek Road. The event reverses direction each year, with clockwise races held in even numbered years. Earth-fill dam 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

3483-575: 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 26 metres (85 ft) high and 475 metres (1,558 ft) long. The 106-thousand-cubic-metre (3.7 × 10 ^  cu ft) dam wall holds back the 801-megalitre (176 × 10 ^  imp gal; 212 × 10 ^  US gal) reservoir when at full capacity. From

3564-498: The Trans Canada Trail development emulated the successful Rails-to-Trails initiative in the United States. The Trail is multi-use and depending on the section may allow hikers, bicyclists, horseback riders, cross-country skiers and snowmobilers. A towpath is a road or path on the bank of a river, canal, or other inland waterway. The original purpose of a towpath was to allow a horse, or a team of human pullers, to tow

3645-654: The US. The term trail has been used by developers and urban planners for a variety of modern paved roads , highways, and boulevards , in these countries, and some highways continue to be officially called a trail, such as the Susquehanna Trail in Pennsylvania, a designation that varies from a two-lane road to a four-lane freeway. An unusual use of the term is in the Canadian province of Alberta , which has multi-lane freeways called trails. Animals created

3726-516: The United States National Trail Classification System, equestrian trails include simple day-use bridle paths and others built to accommodate long strings of pack animals on journeys lasting many days. Trail design parameters for these uses include trail base width and material, trail clear width, trail clear height, access to water suitable for stock (not human) use, and trail routing. A footpath

3807-513: The United States, the East Coast Greenway —3,000 mi (4,828 km) from Key West to the Canadian border — and the 11 September National Memorial Trail, a 1,300 mi (2,092 km) triangular loop connecting the three 9/11 memorial sites, are two long-distance multi-use paths for cyclists, runners, walkers, even equestrians. In Belgium RAVeL , French for réseau autonome de voies lentes ( autonomous network of slow ways ),

3888-445: The United States. The American Canoe Association has compiled a database of water trails in the United States. The National Park Service Rivers, Trails, and Conservation Assistance Program has compiled a list of water trail resources, success stories, and statewide contacts for water trails. Shared use may be achieved by sharing a trail easement, but maintaining segregated and sometimes also separated trail treads within it. This

3969-468: The White Mountains of New Hampshire. The path was blazed in 1819 by Abel Crawford and his son, Ethan Allen. Originally 8.25 miles in length (now 8.5 miles), the trail leads to the summit of Mt. Washington. Trails can be located in different settings for various uses. These can include: Trail segregation, the practice of designating certain trails as having a specific preferred or exclusive use,

4050-404: The base of the dam than at shallower water levels. Thus the stress level of the dam must be calculated in advance of building to ensure that its break level threshold is not exceeded. Overtopping or overflow of an embankment dam beyond its spillway capacity will cause its eventual failure . The erosion of the dam's material by overtopping runoff will remove masses of material whose weight holds

4131-817: The boundaries of estates. These mechanisms are all possible and could apply in different cases. Rail trails or paths are shared-use paths that take advantage of abandoned railway corridors. They can be used for walking, cycling and horseback riding. They exist throughout the world. RailTrails Australia describes them as: Following the route of the railways, they cut through hills, under roads, over embankments and across gullies and creeks. Apart from being great places to walk, cycle or horse ride, rail trails are linear conservation corridors protecting native plants and animals. They often link remnant vegetation in farming areas and contain valuable flora and fauna habitat. Wineries and other attractions are near many trails as well as B&B's and other great places to stay. Most trails have

4212-450: The cost of producing or bringing in concrete would be prohibitive. Rock -fill dams are embankments of compacted free-draining granular earth with an impervious zone. The earth used often contains a high percentage of large particles, hence the term "rock-fill". The impervious zone may be on the upstream face and made of masonry , concrete , plastic membrane, steel sheet piles, timber or other material. The impervious zone may also be inside

4293-434: The dam in place and against the hydraulic forces acting to move the dam. Even a small sustained overtopping flow can remove thousands of tons of overburden soil from the mass of the dam within hours. The removal of this mass unbalances the forces that stabilize the dam against its reservoir as the mass of water still impounded behind the dam presses against the lightened mass of the embankment, made lighter by surface erosion. As

4374-514: The dam is now managed by Seqwater . The Gold Creek Dam was the second oldest large dam in Queensland. Construction of the dam was approved in 1881; surveying began in the same year and was completed by April 1882. The dam wall was built between 1882 and 1885. Due to a lack of water, testing of the facilities was not completed until 1886. Construction was more difficult than expected and caused cost overruns and delays, which led to criticism of

4455-417: The early 21st century. These techniques include concrete overtopping protection systems, timber cribs , sheet-piles , riprap and gabions , Reinforced Earth , minimum energy loss weirs , embankment overflow stepped spillways , and precast concrete block protection systems. All dams are prone to seepage underneath the dam, but embankment dams are prone to seepage through the dam as well; for example,

4536-420: The embankment, in which case it is referred to as a "core". In the instances where clay is used as the impervious material, the dam is referred to as a "composite" dam. To prevent internal erosion of clay into the rock fill due to seepage forces, the core is separated using a filter. Filters are specifically graded soil designed to prevent the migration of fine grain soil particles. When suitable building material

4617-418: The first of its type in the world and the precursor of modern roller compacted concrete (RCC) stepped spillways. The dam and its spillway system were refurbished several times including in 1974 and 2004. Most of the 1890 concrete stepped spillway cascade is still in use. The council had received complaints about the quality of water it was delivering from as early as 1871. Although water supplied from Gold Creek

4698-577: The first trails, which were "later adapted by humans". Subsequently, farmers moved cattle to market along drove roads and between winter and summer grazing creating trails. More recently, former industrial routes, such as railway rights of way and canal towpaths , have been turned into recreational trails. Many historic routes, like the Silk Road , the Amber Road and the Royal Road of

4779-485: The flow of the water and continue to fracture into smaller and smaller sections of earth or rock until they disintegrate into a thick suspension of earth, rocks and water. Therefore, safety requirements for the spillway are high, and require it to be capable of containing a maximum flood stage. It is common for its specifications to be written such that it can contain at least a one-hundred-year flood. A number of embankment dam overtopping protection systems were developed in

4860-479: The foot of the dam is well-formed, reasonably wide and gentle with formed steps on the steeper sections. The track finishes from the east by traversing the bottom of the spillway; it is difficult to make out from the foot of the dam. A 1 kilometre (0.62 mi) side-track visiting a Hoop Pine plantation is described on the information board, which also describes various notable sights on the track. As of March 2010 lantana growth has made these tough to spot. The track

4941-599: The high country [mountains]". Walkway is used similarly in St. John's, Newfoundland , Canada, where the " Grand Concourse ", is an integrated walkway system. In the United Kingdom, the term trail is in common usage. Longer distance walking routes, and government-promoted long-distance paths, collectively known as National Trails , are also frequently called ways as in the Pennine Way and South Downs Way . Generally,

5022-587: The landscape and nature associated with the Romantic movement . In earlier times, walking generally indicated poverty and was associated with vagrancy. In previous centuries long walks were undertaken as part of religious pilgrimages and this tradition continues throughout the world. The first footpath built specifically for recreational hiking in America, and likely the world, is the Crawford Path in

5103-448: The largest earth-filled dam in the world. The principal element of the project is an embankment 9,000 feet (2,700 m) long with a maximum height of 465 feet (142 m). The dam used approximately 200 million cubic yards (152.8 million cu. meters) of fill, which makes it one of the largest man-made structures in the world. Because earthen dams can be constructed from local materials, they can be cost-effective in regions where

5184-423: The mass of the dam erodes, the force exerted by the reservoir begins to move the entire structure. The embankment, having almost no elastic strength, would begin to break into separate pieces, allowing the impounded reservoir water to flow between them, eroding and removing even more material as it passes through. In the final stages of failure, the remaining pieces of the embankment would offer almost no resistance to

5265-601: The multiple environmental and trail conservation efforts by ORV groups will mitigate these issues. Groups such as the BlueRibbon Coalition advocate Treadlightly, which is the responsible use of public lands used for off-road activities. Noise pollution is also a concern, and several studies conducted by Montana State University , California State University , the University of Florida and others have cited possible negative behavioral changes in wildlife as

5346-555: The network. In England and Wales a bridleway is a trail intended for use by equestrians, but walkers also have a right of way , and Section 30 of the Countryside Act 1968 , permits the riding of bicycles (but not motor-cycles) on public bridleways, though the act says it "shall not create any obligation to facilitate the use of the bridleway by cyclists". Thus the right to cycle exists even though it may be difficult to exercise on occasion, especially in winter. Cyclists using

5427-679: The number of complaints dropping to just a few. Gold Creek Dam is reached by traveling to the end of Gold Creek Road, off Brookfield Road in Brookfield . Transport for Brisbane route 435 travels hourly during weekdays from the Indooroopilly Interchange to the Resthaven aged care home at 124 Gold Creek Road, approximately 5 kilometres (3.1 mi) from the Dam. From here to the Dam, Gold Creek Road criss-crosses Gold Creek; it

5508-554: The objectives was to develop a trail that linked up the brumby tracks, mustering and stock routes along the Great Dividing Range, thus providing an opportunity to legally ride the routes of stockmen and drovers who once travelled these areas with pack horses . This Trail provides access to some of the wildest, most remote country in the world. The Bicentennial National Trail is suitable for self-reliant horse riders, fit walkers and mountain bike riders. Within

The Bicentennial National Trail (BNT) in Australia is one of the longest marked multi-use trail in the world, stretching 5,330 km (3,312 mi) from Cooktown, Queensland , through New South Wales to Healesville, Victoria . This trail runs the length of the rugged Great Dividing Range through national parks , private property and alongside of wilderness areas . One of

5670-680: The result of some ORV use. Several US states such as Washington have laws to reduce noise generated by off-road and non-highway vehicles. Water trails , also referred to as blueways or paddling trails, are marked routes on navigable waterways such as rivers , lakes , canals and coastlines for people using small non-motorized boats such as kayaks , canoes , rafts , or rowboats . Some trails may be suitable for float tubing or developed in concert with motorized use. They include: signs and route markers; maps; facilities for parking, boat ramps or docks, and places to camp and picnic. There are also state programs and other promotion for water trails in

5751-410: The right range of size for use in an embankment dam. Earth-fill dams, also called earthen dams, rolled-earth dams or earth dams, are constructed as a simple embankment of well-compacted earth. A homogeneous rolled-earth dam is entirely constructed of one type of material but may contain a drain layer to collect seep water. A zoned-earth dam has distinct parts or zones of dissimilar material, typically

5832-679: The right-of-way to the entire railway system. The Confederation Trail was developed as a tip-to-tip walking/cycling gravel rail trail which doubles as a monitored and groomed snowmobile trail during the winter months, operated by the PEI Snowmobile Association. A considerable part of the Trans Canada trail is repurposed defunct rail lines donated to provincial governments by the Canadian Pacific and Canadian National railways rebuilt as walking trails.

The British Waterways Act 1995 still did not enshrine any right of public access, although it did encourage recreational access of all kinds to the network, although the steady development of the leisure use of the canals and the decline of commercial traffic had resulted in

5994-532: The surface being improved. In France it is possible to cycle, rollerblade , and hike along the banks of the Canal du Midi . A paved stretch of 50 km (31 mi) from Toulouse to Avignonet-Lauragais and another 12 km (7.5 mi) between Béziers and Portiragnes are particularly suited to cycling and rollerblading. It is possible to cycle or walk the entire Canal des Deux Mers from Sète to Bordeaux . Other French canals provide walkers "with many excellent routes, as they are always accompanied by

6075-425: The term footpath is preferred for pedestrian routes, including long-distance trails, and is used for urban paths and sometimes in place of pavement . Track is used for wider paths (wide enough for vehicles), often used for hiking. The terms bridleway , byway , restricted byway are all recognised legal terms and to a greater or lesser extent in general usage. The increased popularity of mountain biking has led to

6156-553: The top of the mountain. EuroVelo bicycle routes are a network of (currently 17) long-distance cycling routes criss-crossing Europe in various stages of completion; more than 90,000 km (55,923 mi) was in place by 2020. EuroVelo is a project of the European Cyclists' Federation (ECF). EuroVelo routes can be used for bicycle touring across the continent, and by local people making short journeys. The routes comprise both existing national bike routes , such as

6237-570: The towpaths were deemed to be private, for the benefit of legitimate users of the canal. The nationalisation of the canal system in 1948 did not result in the towpaths becoming public rights of way, and subsequent legislation, such as the Transport Act of 1968, which defined the government's obligations to the maintenance of the inland waterways for which it was now responsible, did not include any commitment to maintain towpaths for use by anyone. Ten years later British Waterways started to relax

6318-720: The use of less traditional trails. The Robert Wood Johnson Foundation in the US has established the Active Living by Design program to improve the livability of communities in part through developing trails, The Upper Valley Trails Alliance in Vermont has done similar work on traditional trails, while the Somerville Community Path in Somerville, Massachusetts , and related paths, are examples of urban initiatives. In St. John's, Newfoundland, Canada

6399-408: The water is no longer used for supply. The Gold Creek Reservoir track is described as 5.5 kilometres (3.4 mi) long. It starts and ends at the dam and circumnavigates the reservoir. It is suitable for running, walking, and mountain biking by a capable rider but not horse riding. Taken clockwise and starting on the western end of the top of the dam, the first 1.5 kilometres (0.93 mi) (approx)

6480-504: The world is the 233 m-tall (764 ft) Shuibuya Dam in China , completed in 2008. The building of a dam and the filling of the reservoir behind it places a new weight on the floor and sides of a valley. The stress of the water increases linearly with its depth. Water also pushes against the upstream face of the dam, a nonrigid structure that under stress behaves semiplastically, and causes greater need for adjustment (flexibility) near

6561-472: Was deemed to be perfectly drinkable in 1883, dry spring and summer weather resulted in the water being described as discoloured, tainted and foul-smelling. In 1885, the construction of tanks was recommended to allow aeration and sedimentation . After Gold Creek dam was constructed filtration was also recommended. However nothing was initiated, partly due to the lack of a suitable location to treat water from both dams, and because wet weather in 1888 resulted in
