47-453: The Whanganui District Council , formerly spelled Wanganui District Council , is the territorial authority for Whanganui District , New Zealand, comprising the city of Whanganui and its surrounding areas. The council is made up of a mayor and 12 councillors, all elected at-large . They are elected using a first-past-the-post system in triennial elections , with the most recent elections having been held in 2022 . The current mayor

94-545: A mayor–council government . Mayors in New Zealand are directly elected— at-large , by all eligible voters within a territorial authority—in the local elections to a three-year term. The Local Government Act 2002 defines the role of a mayor as having to provide leadership to the other elected members of the territorial authority, be a leader in the community and perform civic duties. Drainage basin Other terms for

141-874: A borough with more than 20,000 people could be proclaimed a city . The boundaries of councils tended to follow the edge of the built-up area, so little distinction was made between the urban area and the local government area. New Zealand's local government structural arrangements were significantly reformed by the Local Government Commission in 1989 when approximately 700 councils and special purpose bodies were amalgamated to create 87 new local authorities. Regional councils were reduced in number from 20 to 13, territorial authorities (city/district councils) from 200 to 75, and special purpose bodies from over 400 to 7. The new district and city councils were generally much larger and most covered substantial areas of both urban and rural land. Many places that once had

188-407: A city council were now being administered by a district council. As a result, the term "city" began to take on two meanings. City also came to be used in a less formal sense to describe major urban areas independent of local body boundaries. This informal usage is jealously guarded. Gisborne, for example, adamantly described itself as the first city in the world to see the new millennium. Gisborne

235-498: A closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as a sink , which may be a permanent lake, a dry lake , or a point where surface water is lost underground . Drainage basins are similar but not identical to hydrologic units , which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system . Hydrologic units are defined to allow multiple inlets, outlets, or sinks. In

282-444: A drainage basin are catchment area , catchment basin , drainage area , river basin , water basin , and impluvium . In North America, they are commonly called a watershed , though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation , a common task in environmental engineering and science. In

329-454: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for

376-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of

423-529: A number of islands where the Minister of Local Government is the territorial authority, two of which have a 'permanent population and/or permanent buildings and structures.' The main islands are listed below (population according to 2001 census in parentheses): In addition, seven of the nine groups of the New Zealand outlying islands are outside of any territorial authority: Territorial authorities have

470-625: A region and a territorial authority. It incorporated the recommendations of the Royal Commission and was established via legislation. Auckland Council is uniquely divided into "local boards" representing the lowest tier of local government. Under the terms of the Local Government Act 2002 , district councils have to represent the interests of their future communities and consider the views of people affected by their decisions. To fulfill that requirement and give young people

517-588: A say in the decision-making process, many councils have a youth council. In late December 2023, the Ashburton District Council scrapped their youth council, stating they could engage better with younger people online and describing the current youth council as "a youth club where they ate pizza." In early January 2024, the Gore District Council opted to restructure its youth council and ruled out dismantling it. In April 2024,

564-794: A small part of the Canadian provinces of Alberta and Saskatchewan , eastern Central America , the islands of the Caribbean and the Gulf, and a small part of northern South America. The Mediterranean Sea basin, with the Black Sea , includes much of North Africa , east-central Africa (through the Nile River ), Southern , Central, and Eastern Europe , Turkey , and the coastal areas of Israel , Lebanon , and Syria . The Arctic Ocean drains most of Western Canada and Northern Canada east of

611-826: A strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of the world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador . Nearly all of South America east of

658-462: A week. Its plan, which went to a Select Committee, accepted the proposal for supercity and many community boards, but rejected proposals for local councils and, initially, no separate seats for Māori . Public reaction to the Royal Commission report was mixed, especially in regards to the Government's amended proposal. Auckland Mayor John Banks supported the amended merger plans. Criticism of

705-737: Is Andrew Tripe . Local government in Whanganui began with the creation of the Wanganui Town Board, within Wellington Province , in 1862. Following the abolishment of the Wellington Province, Wanganui County was founded in 1876. The town board was elevated to a borough council in 1872, and then to a city council in 1924 following amalgamation with the town boards of Wanganui East , Gonville and Castlecliff . Wanganui District Council formed after

752-421: Is administered by a district council, but its status as a city is not generally disputed. Under current law, an urban area has to be at least 50,000 residents before it can be officially proclaimed as a city. Since the 1989 reorganisations, there have been few major reorganisations or status changes in local government. Incomplete list: Reports on completed reorganisation proposals since 1999 are available on

799-487: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

846-412: Is similar to a unitary authority. Territorial authority districts are not subdivisions of regions, and some of them fall within more than one region. Regional council areas are based on water catchment areas, whereas territorial authorities are based on community of interest and road access. Regional councils are responsible for the administration of many environmental and public transport matters, while

893-614: Is the Dead Sea . Drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important. For example, the English crown gave the Hudson's Bay Company a monopoly on the fur trade in the entire Hudson Bay basin, an area called Rupert's Land . Bioregional political organization today includes agreements of states (e.g., international treaties and, within

940-566: The 1989 local government reforms with the amalgamation of the Wanganui City Council with the Wanganui County Council. In 2015, the spelling of the district was changed from Wanganui District to Whanganui District following a request from the council. In October 2023 the council voted to establish a Māori ward for the 2025 and 2028 local elections. The elected mayor and councillors provide governance for

987-713: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

1034-464: The Andes also drains to the Atlantic, as does most of Western and Central Europe and the greatest portion of western Sub-Saharan Africa , as well as Western Sahara and part of Morocco . The two major mediterranean seas of the world also flow to the Atlantic. The Caribbean Sea and Gulf of Mexico basin includes most of the U.S. interior between the Appalachian and Rocky Mountains ,

1081-487: The Chatham Islands Council . District councils serve a combination of rural and urban communities, while city councils administer the larger urban areas . Five territorial authorities ( Auckland , Nelson , Gisborne , Tasman and Marlborough ) also perform the functions of a regional council and thus are unitary authorities . The Chatham Islands Council is a sui generis territorial authority that

1128-765: The Continental Divide , northern Alaska and parts of North Dakota , South Dakota , Minnesota , and Montana in the United States, the north shore of the Scandinavian peninsula in Europe, central and northern Russia, and parts of Kazakhstan and Mongolia in Asia , which totals to about 17% of the world's land. Just over 13% of the land in the world drains to the Pacific Ocean . Its basin includes much of China, eastern and southeastern Russia, Japan,

1175-714: The Korean Peninsula , most of Indochina, Indonesia and Malaysia, the Philippines, all of the Pacific Islands , the northeast coast of Australia , and Canada and the United States west of the Continental Divide (including most of Alaska), as well as western Central America and South America west of the Andes. The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains

1222-784: The Whanganui District Council proposed scrapping its youth council by June 2024 as part of budget saving measures. There are currently 67 territorial authorities. Before the Auckland Council "super merge" in November 2010, there were 73 territorial authorities. Before the Banks Peninsula District Council merged with the Christchurch City Council in 2006, there were 74 territorial authorities. There are

1269-842: The Local Government Commission's site (link below). On 26 March 2009, the Royal Commission on Auckland Governance recommended the Rodney, North Shore, Waitakere, Auckland City, Manukau, Papakura and Franklin territorial councils and the Auckland Regional Council be abolished and the entire Auckland region to be amalgamated into one "supercity". The area would consist of one city council (with statutory provision for three Māori councillors), four urban local councils, and two rural local councils: The National-led Government responded within about

1316-623: The US, interstate compacts ) or other political entities in a particular drainage basin to manage the body or bodies of water into which it drains. Examples of such interstate compacts are the Great Lakes Commission and the Tahoe Regional Planning Agency . In hydrology , the drainage basin is a logical unit of focus for studying the movement of water within the hydrological cycle . The process of finding

1363-684: The Whanganui District Council was adopted in 2015 for use during formal occasions and to be display in the council chamber and outside the council offices. The flag consists of the coat of arms with the Māori and English names of the council beneath it in white, all on a blue field. Territorial authorities of New Zealand Territorial authorities ( Māori: mana ā-rohe ) are the second tier of local government in New Zealand , below regional councils . There are 67 territorial authorities: 13 city councils , 53 district councils and

1410-463: The amended proposal came largely from residents in Manukau, Waitakere and North Shore Cities. In addition, Māori Affairs Minister Pita Sharples spoke against the exclusion of the Māori seats, as recommended by the Royal Commission. Opposition Leader Phil Goff called for a referendum on the issue. Auckland Council was created on 1 November 2010—a unitary authority that is classed as both

1457-406: The basin, it can form tributaries that change the structure of the land. There are three different main types, which are affected by the rocks and ground underneath. Rock that is quick to erode forms dendritic patterns, and these are seen most often. The two other types of patterns that form are trellis patterns and rectangular patterns. Rain gauge data is used to measure total precipitation over

1504-467: The city by setting the policy direction of the council, monitoring its performance, representing the city's interests, and employing the Chief Executive. The Chief Executive runs the everyday business of the council. The Chief Executive is currently David Langford. The council has created a local community board , under the provisions of Part 4 of the Local Government Act 2002 , to represent

1551-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through

1598-405: The district's rural community. The Whanganui Rural Community Board consists of seven elected members. The community board is intended to represent and advocate for the interests of the rural community. Wanganui City Council was granted a Coat of Arms in 1955. The Whanganui District Council has adopted the use of these arms as memorial bearings. The blazon for the arms is: The current flag of

1645-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach

1692-697: The drainage basin to the mouth, and may accumulate there, disturbing the natural mineral balance. This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

1739-857: The eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf , the Indian subcontinent , Burma, and most parts of Australia . The five largest river basins (by area), from largest to smallest, are those of the Amazon (7 million km ), the Congo (4 million km ), the Nile (3.4 million km ), the Mississippi (3.22 million km ), and the Río de la Plata (3.17 million km ). The three rivers that drain

1786-435: The ground and along rivers it can pick up nutrients , sediment , and pollutants . With the water, they are transported towards the outlet of the basin, and can affect the ecological processes along the way as well as in the receiving water body . Modern use of artificial fertilizers , containing nitrogen (as nitrates ), phosphorus , and potassium , has affected the mouths of drainage basins. The minerals are carried by

1833-781: The ground at its terminus, the area can go by several names, such playa, salt flat, dry lake , or alkali sink . The largest endorheic basins are in Central Asia , including the Caspian Sea , the Aral Sea , and numerous smaller lakes. Other endorheic regions include the Great Basin in the United States, much of the Sahara Desert , the drainage basin of the Okavango River ( Kalahari Basin ), highlands near

1880-514: The most water, from most to least, are the Amazon, Ganges , and Congo rivers. Endorheic basin are inland basins that do not drain to an ocean. Endorheic basins cover around 18% of the Earth's land. Some endorheic basins drain to an Endorheic lake or Inland sea . Many of these lakes are ephemeral or vary dramatically in size depending on climate and inflow. If water evaporates or infiltrates into

1927-418: The rainfall on the area of land included in its polygon. These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Calculating the area between these curves and adding up the volume of water is time-consuming. Isochrone maps can be used to show

1974-631: The responsibility of the countries sharing it. Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine

2021-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into

2068-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from

2115-409: The territorial authorities administer local roading and reserves, water supply and sanitation , building consents , the land use and subdivision aspects of resource management, and other local matters. Some activities are delegated to council-controlled organisations . The scope of powers is specified by the Local Government Act 2002 . For many decades until the local government reforms of 1989 ,

2162-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to

2209-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over
