Narrow Neck, Queensland
Narrow Neck is the name of an isthmus that separates the anabranch of the Nerang River from the Coral Sea in the City of Gold Coast, Queensland, Australia. It is also the boundary between the southern end of the suburb of Main Beach and the northern end of the suburb of Surfers Paradise. Seawalls The highway connecting Sydney to Brisbane was constructed at Narrow Neck in 1920 and by 1921 it became necessary to build the Gold Coast's first seawall out of timber. A series of seawalls were constructed at Narrow Neck over the years including materials like car bodies, old trucks and buses filled with concrete, dumped concrete from old buildings, rocks and boulders. After an evaluation of seawalls along the Gold Coast by Griffith Centre for Coastal Management based at Griffith University on the Gold Coast, the timber wall was upgraded in 2016 by City of Gold Coast using the standard rock seawall design for the Gold Coast. Much of the timber removed was still in good condition. Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isthmus
An isthmus (; ; ) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Isthmus vs land bridge vs peninsula ''Isthmus'' and ''land bridge'' are related terms, with isthmus having a broader meaning. A land bridge is an isthmus connecting Earth's major landmasses. The term ''land bridge'' is usually used in biogeology to describe land connections that used to exist between continents at various times and were important for migration of people and various species of animals and plants, e.g. Beringia and Doggerland. An isthmus is a land connection between two bigger landmasses, while a peninsula is rather a land protrusion which is connected to a bigger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g. the Panama C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groyne
A groyne (in the U.S. groin) is a rigid hydraulic structure built perpendicularly from an ocean shore (in coastal engineering) or a river bank, interrupting water flow and limiting the movement of sediment. It is usually made out of wood, concrete, or stone. In the ocean, groynes create beaches, prevent beach erosion caused by longshore drift where this is the dominant process and facilitate beach nourishment. There is also often cross-shore movement which if longer than the groyne will limit its effectiveness. In a river, groynes slow down the process of erosion and prevent ice-jamming, which in turn aids navigation. Groynes run generally perpendicular to the shore, extending from the upper foreshore or beach into the water. All of a groyne may be underwater, in which case it is a ''submerged groyne''. They are often used in tandem with seawalls and other coastal engineering features. Groynes, however, may cause a shoreline to be perceived as unnatural. Groynes are generally ...

Geography Of Gold Coast, Queensland
The Gold Coast is a coastal city in the state of Queensland, Australia, approximately south-southeast of the centre of the state capital Brisbane. With a population over 600,000, the Gold Coast is the sixth-largest city in Australia, the nation's largest regional city, and Queensland's second-largest city after Brisbane. The city's Central Business District is located roughly in the centre of the Gold Coast in the suburb of Southport, with the suburb holding more corporate office space than anywhere else in the city. The urban area of the Gold Coast is concentrated along the coast sprawling almost 60 kilometers, joining up with the Greater Brisbane Metropolitan Area to the north and to the state border with New South Wales to the south. Prior to European settlement the area was occupied by the Yugambeh people. The demonym for the Gold Coast is Gold Coaster. The Gold Coast is a major tourist destination with a sunny, subtropical climate and has become widely known for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southport Cable Hut
The Pacific Cable Station was built in 1902 in Southport, Gold Coast City, Queensland, Australia, continuing to operate for sixty years, finally closing in 1962. While most of the site has been dismantled, the Southport Cable Hut remains and has been listed on the Queensland Heritage Register and the Gold Coast Local Heritage Register. Early telegraphy in Australia Telegraph communication developed in the mid-19th century as a result of many years of discovery and experimentation in electrical communication culminating in the work of Samuel Morse. The rapid long distance communication provided by telegraph systems had a major impact on society. The telegraph was quickly utilised by news services; Associated Press and Reuters press service were founded to take advantage of the technology. Telegraph companies soon offered financial services, providing the facility to send money orders via the telegraph. In Australia the telegraph helped to alleviate the isolation of the colonies. ...

Gold Coast Broadwater
The Gold Coast Broadwater, also known as Southport Broadwater, Gold Coast Harbour and The Broadwater, is a large shallow estuary of water located in the district of South East Queensland, Australia. The estuary reaches from the locality of in the south, to the southern section of the UNESCO World Heritage Listed Moreton Bay in the north. Separated via the Seaway from the Coral Sea by a thin strip of land called Stradbroke Island, the original body of water was a lagoon created from water deposited from the Nerang River. Part of the Broadwater is contained within the Moreton Bay Marine Park. Location and features The entrance of the Nerang River was at Main Beach in the late 19th century but by the 1980s had moved about northwards. The Seaway was completed in 1986 to stabilise the location of the Nerang River Entrance. Its construction has allowed greater tidal flows. This has created a larger tidal range within the Broadwater with lower low tides. Towards the northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geotextile
Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain. Typically made from polypropylene or polyester, geotextile fabrics come in two basic forms: woven (resembling mail bag sacking) and nonwoven (resembling felt). Geotextile composites have been introduced and products such as geogrids and meshes have been developed. Geotextiles are durable and are able to soften a fall. Overall, these materials are referred to as geosynthetics and each configuration—geonets, geosynthetic clay liners, geogrids, geotextile tubes, and others—can yield benefits in geotechnical and environmental engineering design. History Geotextiles were originally intended to be a substitute for granular soil filters. The original, and still sometimes used, term for geotextiles is ''filter fabrics''. Work originally began in the 1950s with R.J. Barrett using geotextiles behind precast concrete seawalls, under precast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longboard (surfing)
A surfboard is a narrow plank used in surfing. Surfboards are relatively light, but are strong enough to support an individual standing on them while riding an ocean wave. They were invented in ancient Hawaii, where they were known as ''papa he'e nalu'' in the Hawaiian language, and were usually made of wood from local trees, such as koa. They were often over in length and extremely heavy. Major advances over the years include the addition of one or more fins (skegs) on the bottom rear of the board to improve directional stability, and numerous improvements in materials and shape. Modern surfboards are made of polyurethane or polystyrene foam covered with layers of fiberglass cloth, and polyester or epoxy resin. The result is a light and strong surfboard that is buoyant and maneuverable. Recent developments in surfboard technology have included the use of carbon fiber and kevlar composites, as well as experimentation in biodegradable and ecologically friendly resins made fr ...

Kite Surfing
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and the more convenient sailing sports. After some concepts emerged in the late 1970s and early 1980s and some designs were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harness. The kitesurfer rides on either a bidirec ...

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations (fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted from ...

Underwater Diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. It is also often referred to as diving, an ambiguous term with several possible meanings, depending on context. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well-adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water. The ambient pressure diver may dive on breath-hold (freediving) or use breathing apparatus for scuba diving or surface-supplied diving, and the saturation diving technique reduces the risk of decompression sickness (DCS) after long-duration deep di ...

Surfing
Surfing is a surface water sport in which an individual, a surfer (or two in tandem surfing), uses a board to ride on the forward section, or face, of a moving wave of water, which usually carries the surfer towards the shore. Waves suitable for surfing are primarily found on ocean shores, but can also be found in standing waves in the open ocean, in lakes, in rivers in the form of a tidal bore, or in wave pools. The term ''surfing'' refers to a person riding a wave using a board, regardless of the stance. There are several types of boards. The Moche of Peru would often surf on reed craft, while the native peoples of the Pacific surfed waves on alaia, paipo, and other such water craft. Ancient cultures often surfed on their belly and knees, while the modern-day definition of surfing most often refers to a surfer riding a wave standing on a surfboard; this is also referred to as stand-up surfing. Another prominent form of surfing is body boarding, where a surfer rides th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
