Rangitata Island
Rangitata Island was 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 was approximately long and about wide at its widest. Low lying, the area is mostly fertile farmland. One of the country's largest delta islands, it was also the only one crossed by State Highway 1 (at the island's northern end), and the only place where the highway left both of the country's two main islands, and also 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, New Zealand, Lyttelton in New Zealand through Christchurch and along the east coast of the ... railway, and once had a small station, which was closed in 1962.

Lens (geometry)
In 2-dimensional geometry, a lens is a convex set, 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 disk (mathematics), circular disks. It can also be formed as the union of two circular segments (regions between the Chord (geometry), 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 f ...

River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Braided River
A braided river (also called braided channel or braided stream) consists of a network of river channel (geography), channels separated by small, often temporary, islands called ''braid bars'' or, in British 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 Stream slope, 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 "Flash flood, flashy" rivers, and with rivers with weak River bank, 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 ...

Rangitata River
The Rangitata River is one of the braided rivers of the Canterbury Plains in southern New Zealand. It flows southeast for from the 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 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 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, Mt Potts, and Erewhon. Erewhon was named by Samuel Butler who was the first white settler to live at the Mesopotamia sheep station. Erewhon is also the name of a novel written by Butler anonymously in 1872.

River Islands Of New Zealand
A river is a natural stream of fresh water that flows on land or inside Subterranean river, caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle, the processes by which water moves around the Earth. Water first enters rivers through precipitation, whether from rainfall, the Runoff (hydrology), runoff of water down a slope, the melting of glaciers or snow, or seepage from aquifers beneath the surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins, or catchments, areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their Bank (geography), banks and flood the surrounding area, spreading nutrients to the surrounding area.
