A drainage basin is an area of land in which all flowing surface water converges to a single point, such as a river mouth , or flows into another body of water , such as a lake or ocean . A basin is separated from adjacent basins by a perimeter, the drainage divide , made up of a succession of elevated features, such as ridges and hills . A basin may consist of smaller basins that merge at river confluences , forming a hierarchical pattern .

81-514: The Kavvayi river basin is located between 120 05’ to 120 15’ North latitude and 750 05 ‘ to 750 20’ East longitude. It spread over the district of Kannur and Kasargod . It has a total area of 164.76 km2 covering 14 villages spread over 9 local bodies in the two districts. Kavvayi river or Thattar river emerges from the Cheemeni Kunnu at elevation 114 m. above MSL having the length of 31 km and join directly to Kavvai backwater. Kavvayi river

162-484: 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 a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of

243-613: A subarctic climate (Köppen Dfc ) with a shorter summer season. Summers can get very hot, sometimes above 38 °C (100 °F) during the day, and with humidity decreasing from northeast to southwest. Warm southern winds blow from the plains and intermontane regions of the Western United States during much of July and August, very cool or hot but changeable air masses often occur during spring and in September. Winters are usually bitterly cold, with frequent Arctic air descending from

324-414: 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 a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as

405-961: A European-Canadian style of prosperous agrarian society . The long-term prosperity of the province depended on the world price of grain, which headed steadily upward from the 1880s to 1920, then plunged down. Wheat output was increased by new strains, such as the " Marquis wheat " strain which matured 8 days sooner and yielded 7 more bushels per acre (0.72 m /ha) than the previous standard, " Red Fife ". The national output of wheat soared from 8 million imperial bushels (290,000 m ) in 1896, to 26 × 10 ^  imp bu (950,000 m ) in 1901, reaching 151 × 10 ^  imp bu (5,500,000 m ) by 1921. Urban reform movements in Regina were based on support from business and professional groups. City planning, reform of local government, and municipal ownership of utilities were more widely supported by these two groups, often through such organizations as

486-449: 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

567-540: 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

648-513: A warm summer, corresponding to its humid continental climate ( Köppen type Dfb ) in the central and most of the eastern parts of the province, as well as the Cypress Hills ; drying off to a semi-arid steppe climate (Köppen type BSk ) in the southwestern part of the province. Drought can affect agricultural areas during long periods with little or no precipitation at all. The northern parts of Saskatchewan – from about La Ronge northward – have

972-708: Is presently governed by Premier Scott Moe , the leader of the Saskatchewan Party , which has been in power since 2007. In 1992, the federal and provincial governments signed a historic land claim agreement with First Nations in Saskatchewan . The First Nations received compensation which they could use to buy land on the open market for the bands. They have acquired about 3,079 km (761,000 acres; 1,189 sq mi), new reserve lands under this process. Some First Nations have used their settlement to invest in urban areas, including Regina and Saskatoon. The name of

1053-480: 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

1134-600: 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

1215-476: Is the only province without a natural border . As its borders follow geographic lines of longitude and latitude , the province is roughly a quadrilateral , or a shape with four sides. However, the southern border on the 49th parallel and the northern border on the 60th parallel curve to the left as one proceeds east, as do all parallels in the Northern Hemisphere. Additionally, the eastern boundary of

The question on knowledge of languages allows for multiple responses. According to

1539-415: The 2021 census , religious groups in Saskatchewan included: Historically, Saskatchewan's economy was primarily associated with agriculture , with wheat being the precious symbol on the province's flag. Increasing diversification has resulted in agriculture, forestry , fishing , and hunting only making up 8.9% of the province's GDP in 2018. Saskatchewan grows a large portion of Canada's grain. In 2017,

1620-682: 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

The Crown also entered into a series of numbered treaties with the indigenous peoples of the area, which serve as the basis of the relationship between First Nations , as they are called today, and the Crown. Since the late twentieth century, land losses and inequities as a result of those treaties have been subject to negotiation for settlement between

2025-558: The Sarcee , Niitsitapi , Atsina , Cree , Saulteaux , Assiniboine (Nakoda), and Sioux . The first known European to enter Saskatchewan was Henry Kelsey from England in 1690, who travelled up the Saskatchewan River in hopes of trading fur with the region's indigenous peoples. Fort La Jonquière and Fort de la Corne were first established in 1751 and 1753 by early French explorers and traders. The first permanent European settlement

Saskatchewan Saskatchewan is a province in Western Canada . It is bordered on the west by Alberta , on the north by the Northwest Territories , on the east by Manitoba , to the northeast by Nunavut , and to

2268-1081: The oil industry is larger. Among Canadian provinces, only Alberta exceeds Saskatchewan in overall oil production. Heavy crude is extracted in the Lloydminster-Kerrobert-Kindersley areas. Light crude is found in the Kindersley-Swift Current areas as well as the Weyburn-Estevan fields. Natural gas is found almost entirely in the western part of Saskatchewan, from the Primrose Lake area through Lloydminster, Unity, Kindersley, Leader, and around Maple Creek areas. Major companies based in Saskatchewan include Nutrien , Federated Cooperatives Ltd. and Cameco . Major Saskatchewan-based Crown corporations are Saskatchewan Government Insurance (SGI), SaskTel , SaskEnergy (the province's main supplier of natural gas), SaskPower , and Saskatchewan Crop Insurance Corporation (SCIC). Bombardier runs

2592-524: The Board of Trade. Church-related and other altruistic organizations generally supported social welfare and housing reforms; these groups were generally less successful in getting their own reforms enacted. The province responded to the First World War in 1914 with patriotic enthusiasm and enjoyed the resultant economic boom for farms and cities alike. Emotional and intellectual support for the war emerged from

2673-842: The Cypress Hills, and Wood Mountain Post in south-central Saskatchewan near the United States border. Many Métis people, who had not been signatories to a treaty, had moved to the Southbranch Settlement and Prince Albert district north of present-day Saskatoon following the Red River Rebellion in Manitoba in 1870. In the early 1880s, the Canadian government refused to hear the Métis' grievances, which stemmed from land-use issues. Finally, in 1885,

It declined and disappeared, subject to widespread political and media opposition, plus internal scandals involving the use of the organization's funds. In 1970, the first annual Canadian Western Agribition was held in Regina. This farm-industry trade show, with its strong emphasis on livestock, is rated as one of the five top livestock shows in North America, along with those in Houston , Denver , Louisville and Toronto . The province celebrated

2916-608: The Métis, led by Louis Riel , staged the North-West Rebellion and declared a provisional government. They were defeated by a Canadian militia brought to the Canadian prairies by the new Canadian Pacific Railway. Riel, who surrendered and was convicted of treason in a packed Regina courtroom, was hanged on November 16, 1885. Since then, the government has recognized the Métis as an aboriginal people with status rights and provided them with various benefits. The national policy set by

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

3240-523: The area in 1690 and first settled in the area in 1774. It became a province in 1905, carved out from the vast North-West Territories , which had until then included most of the Canadian Prairies . In the early 20th century, the province became known as a stronghold for Canadian social democracy; North America's first social-democratic government was elected in 1944 . The province's economy is based on agriculture , mining , and energy . Saskatchewan

3402-406: 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

3483-430: 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

3564-417: The distinction of being the only Canadian province for which no borders correspond to physical geographic features (i.e. they are all parallels and meridians). Along with Alberta, Saskatchewan is one of only two land-locked provinces. The overwhelming majority of Saskatchewan's population is in the southern third of the province, south of the 53rd parallel . Saskatchewan contains two major natural regions:

3645-441: 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

3726-692: 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

3807-821: 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

The provincial government has responded to the threat of climate change by introducing a plan to reduce carbon emissions , "The Saskatchewan Energy and Climate Change Plan", in June 2007. Saskatchewan has been populated by various indigenous peoples of North America , including members of

3969-408: The export market. Population quintupled from 91,000 in 1901 to 492,000 in 1911, thanks to heavy immigration of farmers from Ukraine, U.S., Germany and Scandinavia. Efforts were made to assimilate the newcomers to British Canadian culture and values. In the 1905 provincial elections, Liberals won 16 of 25 seats in Saskatchewan. The Saskatchewan government bought out Bell Telephone Company in 1909, with

4050-661: The federal government, the Canadian Pacific Railway , the Hudson's Bay Company and associated land companies encouraged immigration. The Dominion Lands Act of 1872 permitted settlers to acquire one-quarter of a square mile of land to homestead and offered an additional quarter upon establishing a homestead. In 1874, the North-West Mounted Police began providing police services. In 1876, the North-West Territories Act provided for appointment, by

4131-511: The flexibility exhibited by farm women in performing productive and nonproductive labour was critical to the survival of family farms, and thus to the success of the wheat economy. On September 1, 1905, Saskatchewan became a province, with inauguration day held on September 4. Its political leaders at the time proclaimed its destiny was to become Canada's most powerful province. Saskatchewan embarked on an ambitious province-building program based on its Anglo-Canadian culture and wheat production for

Premier Walter Scott preferred government assistance to outright ownership because he thought enterprises worked better if citizens had a stake in running them; he set up the Saskatchewan Cooperative Elevator Company in 1911. Despite pressure from farm groups for direct government involvement in

4293-515: The grain handling business, the Scott government opted to loan money to a farmer-owned elevator company. Saskatchewan in 1909 provided bond guarantees to railway companies for the construction of branch lines, alleviating the concerns of farmers who had trouble getting their wheat to market by waggon. The Saskatchewan Grain Growers Association , was the dominant political force in the province until

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

4779-559: The need for a wife. In 1901, there were 19,200 families, but this surged to 150,300 families only 15 years later. Wives played a central role in settlement of the prairie region. Their labour, skills, and ability to adapt to the harsh environment proved decisive in meeting the challenges. They prepared bannock, beans and bacon, mended clothes, raised children, cleaned, tended the garden, helped at harvest time and nursed everyone back to health. While prevailing patriarchal attitudes, legislation, and economic principles obscured women's contributions,

4860-500: The north, and with high temperatures not breaking −17 °C (1 °F) for weeks at a time. Warm chinook winds often blow from the west, bringing periods of mild weather. Annual precipitation averages 30 to 45 centimetres (12 to 18 inches) across the province, with the bulk of rain falling in June, July, and August. Saskatchewan is one of the most tornado -active parts of Canada , averaging roughly 12 to 18 tornadoes per year, some violent. In 2012, 33 tornadoes were reported in

4941-653: The politics of Canadian national identity, the rural myth, and social gospel progressivism The Church of England was especially supportive. However, there was strong hostility toward German-Canadian farmers. Recent Ukrainian immigrants were enemy aliens because of their citizenship in the Austro-Hungarian Empire. A small fraction were taken to internment camps. Most of the internees were unskilled unemployed labourers who were imprisoned "because they were destitute, not because they were disloyal". The price of wheat tripled and acreage seeded doubled. The wartime spirit of sacrifice intensified social reform movements that had predated

Anthony Henday's spelling was Keiskatchewan , with the modern rendering, Saskatchewan , being officially adopted in 1882, when a portion of the present-day province was designated a provisional district of the North-West Territories . Saskatchewan

5265-584: The province was −56.7 °C (−70.1 °F) in Prince Albert , north of Saskatoon, in February 1893. The effects of climate change in Saskatchewan are now being observed in parts of the province. There is evidence of reduction of biomass in Saskatchewan's boreal forests (as with those of other Canadian prairie provinces ) is linked by researchers to drought-related water stress, stemming from global warming , most likely caused by greenhouse gas emissions . While studies as early as 1988 (Williams, et al., 1988) have shown climate change will affect agriculture,

5346-594: The province, while the northern half is mostly forested and sparsely populated. Roughly half live in the province's largest city, Saskatoon , or the provincial capital, Regina . Other notable cities include Prince Albert , Moose Jaw , Yorkton , Swift Current , North Battleford , Estevan , Weyburn , Melfort , and the border city of Lloydminster . English is the primary language of the province, with 82.4% of Saskatchewanians speaking English as their first language . Saskatchewan has been inhabited for thousands of years by indigenous peoples . Europeans first explored

5427-473: The province. The Regina Cyclone took place in June 1912 when 28 people died in an F4 Fujita scale tornado. Severe and non-severe thunderstorm events occur in Saskatchewan, usually from early spring to late summer. Hail, strong winds and isolated tornadoes are a common occurrence. The hottest temperature ever recorded in Saskatchewan was in July 1937 when the temperature rose to 45 °C (113 °F) in Midale and Yellow Grass . The coldest ever recorded in

Languages of Saskatchewan (2016): Indigenous and visible minority identity (2021): According to the 2011 Canadian census , the largest ethnic group in Saskatchewan is German (28.6%), followed by English (24.9%), Scottish (18.9%), Canadian (18.8%), Irish (15.5%), Ukrainian (13.5%), French ( Fransaskois ) (12.2%), First Nations (12.1%), Norwegian (6.9%), and Polish (5.8%). As of

5670-572: 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

5751-461: 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

5832-399: The south by the United States ( Montana and North Dakota ). Saskatchewan and Alberta are the only landlocked provinces of Canada. In 2024, Saskatchewan's population was estimated at 1,239,865. Nearly 10% of Saskatchewan's total area of 651,900 km (251,700 sq mi) is fresh water, mostly rivers, reservoirs, and lakes . Residents live primarily in the southern prairie half of

5913-524: The southern shore of Lake Athabasca . Southern Saskatchewan contains another area with sand dunes known as the "Great Sand Hills" covering over 300 km (120 sq mi). The Cypress Hills , in the southwestern corner of Saskatchewan and Killdeer Badlands ( Grasslands National Park ), are areas of the province that were unglaciated during the last glaciation period, the Wisconsin glaciation . The province's highest point, at 1,392 m (4,567 ft),

5994-418: 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

6075-418: The taking of indigenous lands by various governments. The federal and provincial governments have negotiated on numerous land claims, and developed a program of "Treaty Land Entitlement", enabling First Nations to buy land to be taken into reserves with money from settlements of claims. "In 1992, the federal and provincial governments signed an historic land claim agreement with Saskatchewan First Nations. Under

6156-415: 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

6237-477: 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

6318-549: The war and now came to fruition. Saskatchewan gave women the right to vote in 1916 and at the end of 1916 passed a referendum to prohibit the sale of alcohol. In the late 1920s, the Ku Klux Klan , imported from the United States and Ontario, gained brief popularity in nativist circles in Saskatchewan and Alberta. The Klan, briefly allied with the provincial Conservative party because of their mutual dislike for Premier James G. "Jimmy" Gardiner and his Liberals (who ferociously fought

6399-641: 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 the Andes also drains to the Atlantic, as does most of Western and Central Europe and

6480-495: Was a Hudson's Bay Company post at Cumberland House , founded in 1774 by Samuel Hearne . The southern part of the province was part of Spanish Louisiana from 1762 until 1802. In 1803, the Louisiana Purchase transferred from France to the United States part of what is now Alberta and Saskatchewan. In 1818, the U.S. ceded the area to Britain. Most of what is now Saskatchewan was part of Rupert's Land and controlled by

6561-414: Was far harsher, especially for the first arrivals who lived in sod houses . However eastern money poured in and by 1913, long term mortgage loans to Saskatchewan farmers had reached $ 65 million. The dominant groups comprised British settlers from eastern Canada and Britain, who comprised about half of the population during the late 19th and early 20th centuries. They played the leading role in establishing
