Rangitata Island
Rangitata Island is a long lens-shaped island in the delta of the braided Rangitata River in Canterbury, New Zealand, approximately halfway between Timaru and Ashburton, New Zealand. The island is approximately long and about wide at its widest. Low lying, it is mostly fertile farmland. One of the country's largest delta islands, it is also the only one crossed by State Highway 1 (at the island's northern end), and the only place where the highway leaves both of the country's two main islands. It is also crossed by the Main South Line The Main South Line, sometimes referred to as part of the South Island Main Trunk Railway, is a railway line that runs north and south from Lyttelton in New Zealand through Christchurch and along the east coast of the South Island to Inverca ... railway, and once had a small station, which was closed in 1962.

Lens (geometry)
In 2-dimensional geometry, a lens is a convex region bounded by two circular arcs joined to each other at their endpoints. In order for this shape to be convex, both arcs must bow outwards (convex-convex). This shape can be formed as the intersection of two circular disks. It can also be formed as the union of two circular segments (regions between the chord of a circle and the circle itself), joined along a common chord. Types If the two arcs of a lens have equal radius, it is called a symmetric lens, otherwise is an asymmetric lens. The vesica piscis is one form of a symmetric lens, formed by arcs of two circles whose centers each lie on the opposite arc. The arcs meet at angles of 120° at their endpoints. Area ;Symmetric The area of a symmetric lens can be expressed in terms of the radius ''R'' and arc lengths ''θ'' in radians: :A = R^2\left(\theta - \sin \theta \right). ;Asymmetric The area of an asymmetric lens formed from circles of radii ''R'' and ''r'' with ...

River Delta
A river delta is a landform shaped like a triangle, created by deposition (geology), deposition of sediment that is carried by a river and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. It is so named because its triangle shape resembles the Greek letter Delta. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment, and receiving basin processes that redistribute, sequester, and export that sediment. The size, geometry, and location of the receiving basin also plays an important role in delta evolution. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide Coast, coastline defense and can impact drinking water supply. They are also Ecology, ecologically important, with different species' assemblages ...

Braided River
A braided river, or braided channel, consists of a network of river channels separated by small, often temporary, islands called braid bars or, in English usage, ''aits'' or ''eyots''. Braided streams tend to occur in rivers with high sediment loads or coarse grain sizes, and in rivers with steeper slopes than typical rivers with straight or meandering channel patterns. They are also associated with rivers with rapid and frequent variation in the amount of water they carry, i.e., with "flashy" rivers, and with rivers with weak banks. Braided channels are found in a variety of environments all over the world, including gravelly mountain streams, sand bed rivers, on alluvial fans, on river deltas, and across depositional plains. Description A braided river consists of a network of multiple shallow channels that diverge and rejoin around ephemeral ''braid bars''. This gives the river a fancied resemblance to the interweaved strands of a braid. The braid bars, also known as channel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rangitata River
The Rangitata River is one of the braided rivers that helped form the Canterbury Plains in southern New Zealand. It flows southeast for from the Southern Alps (New Zealand), Southern Alps, entering the Pacific Ocean northeast of Timaru. The river has a catchment area of , and a mean annual flow of at Klondyke. The Māori language, Māori name "Rangitata" (Rakitata) has been variously translated as "day of lowering clouds", "close sky", and "the side of the sky". The river formed the Rangitata Valley, in the center of the Southern Alps, and the on-location photography of the Edoras set from ''The Lord of the Rings: The Two Towers'', and ''The Lord of the Rings: The Return of the King, The Return of the King'' was filmed in this valley, on and around Mount Sunday. Several remote sheep stations are located near Mount Sunday. These include Mesopotamia (station), Mesopotamia, Mt Potts, and Erewhon. Erewhon was named by Samuel Butler (novelist), Samuel Butler who was the first white ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand State Highway 1
State Highway 1 (SH 1) is the longest and most significant road in the New Zealand road network, running the length of both main islands. It appears on road maps as SH 1 and on road signs as a white number 1 on a red shield, but it has the official designations SH 1N in the North Island, SH 1S in the South Island.

Main South Line
The Main South Line, sometimes referred to as part of the South Island Main Trunk Railway, is a railway line that runs north and south from Lyttelton in New Zealand through Christchurch and along the east coast of the South Island to Invercargill via Dunedin. It is one of the most important railway lines in New Zealand and was one of the first to be built, with construction commencing in the 1860s. At Christchurch, it connects with the Main North Line to Picton, the other part of the South Island Main Trunk. Construction Construction of the Main South Line falls into two main sections: from Christchurch through southern Canterbury to Otago's major city of Dunedin; and linking the southern centres of Dunedin and Invercargill, improving communication in southern Otago and large parts of Southland. Construction of the first section of the line began in 1865 and the whole line was completed on 22 January 1879. Christchurch-Dunedin section The Canterbury provincial government ...

River Islands Of New Zealand
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...
