Waiuna Lagoon is a lake in the Southland Region of New Zealand's South Island, just inland from Big Bay. It is 15 metres above sea level, and is drained by the Awarua River. [1]
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.
Longshore drift from longshore current is a geological process that consists of the transportation of sediments along a coast parallel to the shoreline, which is dependent on the angle incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves parallel to the coast. Longshore drift is simply the sediment moved by the longshore current. This current and sediment movement occur within the surf zone. The process is also known as littoral drift.
Chatham Island is by far the largest island of the Chatham Islands group, in the south Pacific Ocean off the eastern coast of New Zealand's South Island. It is said to be "halfway between the equator and the pole, and right on the International Date Line", though the point in fact lies ca. 173 miles WSW of the island's westernmost point. The island is called Rekohu in Moriori, and Wharekauri in Māori.
Ōkārito Lagoon is a coastal lagoon on the West Coast of New Zealand's South Island. It is located 130 kilometres (81 mi) south of Hokitika, and covers an area of about 3,240 hectares (12.5 sq mi), making it the largest unmodified coastal wetland in New Zealand. It preserves a sequence of vegetation types from mature rimu forest through mānuka scrub to brackish water that has been lost in much of the rest of the West Coast. Ōkārito Lagoon is the main feeding ground for New Zealand's only breeding population of rare white heron. The settlement of Ōkārito is at the southern end of the lagoon.
Te Whanga Lagoon dominates the geography of Chatham Island, in the South Pacific Ocean off New Zealand's east coast. It covers 160 square kilometres (62 sq mi).
Te Awarua-o-Porirua Harbour, commonly known as Porirua Harbour, is a natural inlet in the south-western coast of the North Island of New Zealand.
Saltwater Lagoon is a lagoon located on the West Coast of New Zealand's South Island.
The New Zealand bittern is an extinct and enigmatic species of heron in the family Ardeidae. It was endemic to New Zealand and was last recorded alive in the 1890s.
Māngere Lagoon is a lagoon in the Manukau Harbour, New Zealand. It occupies a volcanic crater or maar which is part of the Auckland volcanic field. Oval and about 600m long, it has a small restored scoria island remaining in the centre.
The Awarua Wetland is a peatland area of 20,000 hectares in the Southland Region of New Zealand. The site, which was initially an area of about 3,556 hectares, was designated as having international significance under the Ramsar Convention in 1976, using the name Waituna Wetlands Scientific Reserve.
The Ōkārito River is a river of the West Coast Region of New Zealand's South Island. It flows northwest from the northern end of Lake Mapourika, reaching the Ōkārito Lagoon 15 kilometres west of Whataroa.
The Pororari River, with an older spelling of Porarari, is a river of the West Coast Region of New Zealand's South Island. It flows northwest from its sources in the Paparoa Range, reaching the Tasman Sea at Punakaiki via Pororari Lagoon. Cave Creek / Kotihotiho is a tributary to the river. There are opportunities to tramp along this river, with two different options accommodating multi-hour loop walks. Further upstream, the Pororari River is followed by the new Paparoa Track, which provides an opportunity for multi-day tramping or mountain biking.
The Totarakaitorea River is a short river of the West Coast Region of New Zealand's South Island. It flows west to reach the Three Mile Lagoon three kilometres to the south of Okarito.
Half Mile Lagoon is a lake in the Northland Region of New Zealand. It is located 5 km to the northwest of Ngataki, on the Aupouri Peninsula.
Waitahora Lagoon is a lake in the Northland Region of New Zealand.
Ōkārito is a small coastal settlement on the West Coast of New Zealand's South Island, 127 kilometres (79 mi) southwest of Hokitika, and 10 kilometres (6.2 mi) from State Highway 6. It is built at the southern end of the Ōkārito Lagoon at the mouth of the Ōkārito River. The settlement of The Forks is located just inland, on the banks of the river.
A hapua is a river-mouth lagoon on a mixed sand and gravel (MSG) beach, formed at the river-coast interface where a typically braided, although sometimes meandering, river interacts with a coastal environment that is significantly affected by longshore drift. The lagoons which form on the MSG coastlines are common on the east coast of the South Island of New Zealand and have long been referred to as hapua by the Māori. This classification differentiates hapua from similar lagoons located on the New Zealand coast termed waituna.
Waiau Glacier Coast Marine Reserve is a marine reserve of the West Coast Region of New Zealand's South Island. It covers an area of 4,641 hectares or 46 km2, from 11 km south from Kohuamarua Bluff near Ōkārito, to Omoeroa Bluff, and about 4 km out to sea.
Coopers Lagoon / Muriwai is a small coastal waituna-type lagoon in the Canterbury region of New Zealand, located approximately half way between the mouth of the Rakaia River and the outlet of the much larger Lake Ellesmere / Te Waihora. While the present-day lagoon is separated from the nearby Canterbury Bight by approximately 100 metres (330 ft), the water of the lagoon is considered brackish and early survey maps show that, until recently, the lagoon was connected to the ocean by a small channel. The lagoon, along with the surrounding wetlands, has historically been an important mahinga kai for local Māori.
A waituna is a freshwater coastal lagoon on a mixed sand and gravel (MSG) beach, formed where a braided river meets a coastline affected by longshore drift. This type of waterbody is neither a true lake, lagoon nor estuary.
