90-559: This river does not belong to the basin of the larger river Neman , but the two rivers' names are related in several languages: The European Union gave 100,000 euros to establish tourist routes along the Nemunėlis. It is expected that the Latvian and Lithuanian initiative will be completed in 2007, as new kayak and boat rental businesses open and new campsites, tourist guides, and information signs are prepared. This article related to

180-540: 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 . Other terms for a drainage basin are catchment area , catchment basin , drainage area , river basin , water basin , and impluvium . In North America, they are commonly called

270-484: 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

360-414: 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

450-449: 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

540-540: 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

630-567: A few fossils are the Belly River Group and St. Mary River Formations of the southwest and the northwestern Wapiti Formation , which contains two Pachyrhinosaurus bone beds. The Bearpaw Formation represents strata deposited during a marine transgression . Dinosaurs are known from this formation, but represent specimens washed out to sea or reworked from older sediments . Paleo-Indians arrived in Alberta at least 10,000 years ago, toward

720-466: A high rate of interprovincial migration compared to other provinces. In 2016, Alberta continued to have the youngest population among the provinces with a median age of 36.7 years, compared with the national median of 41.2 years. Also in 2016, Alberta had the smallest proportion of seniors (12.3%) among the provinces and one of the highest population shares of children (19.2%), further contributing to Alberta's young and growing population. About 81% of

810-530: A land area of 634,658.27 km (245,042.93 sq mi), it had a population density of 6.7/km in 2021. Statistics Canada estimated the province to have a population of 4,800,768 in Q1 of 2024. Since 2000, Alberta's population has experienced a relatively high rate of growth, mainly because of its burgeoning economy. Between 2003 and 2004, the province had high birthrates (on par with some larger provinces such as British Columbia), relatively high immigration, and

900-410: A part of the province's identity. Since Alberta is the province most rich in hydrocarbons, it provides 70% of the oil and natural gas produced on Canadian soil. In 2018, Alberta's output was CA$ 338.2 billion, 15.27% of Canada's GDP. Until the 1930s, Alberta's political landscape consisted of two major parties: the centre-left Liberals and the agrarian United Farmers of Alberta . Today, Alberta

1080-477: A semi-arid steppe climate because the annual precipitation is less than the water that evaporates or is used by plants . The southeastern corner of Alberta, part of the Palliser Triangle , experiences greater summer heat and lower rainfall than the rest of the province, and as a result, suffers frequent crop yield problems and occasional severe droughts. Western Alberta is protected by the mountains and enjoys

1170-634: A tributary of the Mackenzie River . Alberta's capital city, Edmonton , is at about the geographic centre of the province. It is the most northerly major city in Canada and serves as a gateway and hub for resource development in northern Canada. With its proximity to Canada's largest oil fields, the region has most of western Canada's oil refinery capacity. Calgary is about 280 km (170 mi) south of Edmonton and 240 km (150 mi) north of Montana, surrounded by extensive ranching country. Almost 75% of

1260-500: A type of intense, fast-moving winter storm that generally forms over or near the province and, pushed with great speed by the continental polar jetstream , descends over the rest of southern Canada and the northern tier of the United States. In southwestern Alberta, the cold winters are frequently interrupted by warm, dry Chinook winds blowing from the mountains, which can propel temperatures upward from frigid conditions to well above

1350-522: Is generally perceived as a conservative province. The right-wing Social Credit Party held office continually from 1935 to 1971 before the centre-right Progressive Conservatives held office continually from 1971 to 2015, the latter being the longest unbroken run in government at the provincial or federal level in Canadian history. Since before becoming part of Canada, Alberta has been home to several First Nations like Plains Indians and Woodland Cree . It

1440-480: 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

1530-600: 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

1620-403: Is the fourth-largest province by area at 661,848 square kilometres (255,541 square miles), and the fourth-most populous, being home to 4,262,635 people. Alberta's capital is Edmonton , while Calgary is its largest city. The two are Alberta's largest census metropolitan areas . More than half of Albertans live in either Edmonton or Calgary, which contributes to continuing the rivalry between

1710-512: The 2013 Alberta floods Alberta experienced heavy rainfall that triggered catastrophic flooding throughout much of the southern half of the province along the Bow , Elbow , Highwood and Oldman rivers and tributaries. A dozen municipalities in Southern Alberta declared local states of emergency on June 21 as water levels rose and numerous communities were placed under evacuation orders. In 2016,

1800-441: The 2021 Canadian Census , the ten most spoken languages in the province included English (4,109,720 or 98.37%), French (260,415 or 6.23%), Tagalog (172,625 or 4.13%), Punjabi (126,385 or 3.03%), Spanish (116,070 or 2.78%), Hindi (94,015 or 2.25%), Mandarin (82,095 or 1.97%), Arabic (76,760 or 1.84%), Cantonese (74,960 or 1.79%), and German (65,370 or 1.56%). The question on knowledge of languages allows for multiple responses. As of

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,

2160-651: The Drumheller Valley and Edmonton regions there are exposed Horseshoe Canyon facies . Other formations have been recorded as well, like the Milk River and Foremost Formations. The latter two have a lower diversity of documented dinosaurs, primarily due to their lower total fossil quantity and neglect from collectors who are hindered by the isolation and scarcity of exposed outcrops. Their dinosaur fossils are primarily teeth recovered from microvertebrate fossil sites. Additional geologic formations that have produced only

2250-554: The Fort McMurray wildfire resulted in the largest fire evacuation of residents in Alberta's history, as more than 80,000 people were ordered to evacuate. From 2020 until restrictions were lifted in 2022, Alberta was affected by the COVID-19 pandemic . The 2021 Canadian census reported Alberta had a population of 4,262,635 living in 1,633,220 of its 1,772,670 total dwellings, an 4.8% change from its 2016 population of 4,067,175. With

2340-527: The Government of Alberta has operated a rat-control program, which has been so successful that only isolated instances of wild rat sightings are reported, usually of rats arriving in the province aboard trucks or by rail. In 2006, Alberta Agriculture reported zero findings of wild rats; the only rat interceptions have been domesticated rats that have been seized from their owners. It is illegal for individual Albertans to own or keep Norwegian rats of any description;

It was there he discovered the mighty outflow river which bears his name—the Mackenzie River —which he followed to its outlet in the Arctic Ocean. Returning to Lake Athabasca, he followed the Peace River upstream, eventually reaching the Pacific Ocean, and so he became the first European to cross the North American continent north of Mexico. The extreme southernmost portion of Alberta

3330-541: The District of Alberta was enlarged and given provincial status, with the election of Alexander Cameron Rutherford as the first premier. Less than a decade later, the First World War presented special challenges to the new province as an extraordinary number of volunteers left relatively few workers to maintain services and production. Over 50% of Alberta's doctors volunteered for service overseas. On June 21, 2013, during

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

3690-642: The animals can only be kept in the province by zoos, universities and colleges, and recognized research institutions. In 2009, several rats were found and captured, in small pockets in southern Alberta, putting Alberta's rat-free status in jeopardy. A colony of rats was subsequently found in a landfill near Medicine Hat in 2012 and again in 2014. Alberta has one of the greatest diversities and abundances of Late Cretaceous dinosaur fossils worldwide. Taxa are represented by complete fossil skeletons, isolated material, microvertebrate remains, and even mass graves . At least 38 dinosaur type specimens were collected in

3780-473: The badlands terrain, desert flora, and remnants from Alberta's past when dinosaurs roamed the then lush landscape. Alberta extends for over 1,200 km (750 mi) from north to south; its climate, therefore, varies considerably. Average high temperatures in January range from 0 °C (32 °F) in the southwest to −24 °C (−11 °F) in the far north. The presence of the Rocky Mountains also influences

3870-406: 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

3960-403: The climate to the southwest, which disrupts the flow of the prevailing westerly winds and causes them to drop most of their moisture on the western slopes of the mountain ranges before reaching the province, casting a rain shadow over much of Alberta. The northerly location and isolation from the weather systems of the Pacific Ocean cause Alberta to have a dry climate with little moderation from

4050-430: 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

4140-441: 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

4230-692: 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

4320-467: The dry prairie of the southeast. The northern and western parts of the province experience higher rainfall and lower evaporation rates caused by cooler summer temperatures. The south and east-central portions are prone to drought-like conditions sometimes persisting for several years, although even these areas can receive heavy precipitation, sometimes resulting in flooding. In the winter, the Alberta clipper ,

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

4500-515: The end of the last ice age . They are thought to have migrated from Siberia to Alaska on a land bridge across the Bering Strait and then possibly moved down the east side of the Rocky Mountains through Alberta to settle the Americas . Others may have migrated down the coast of British Columbia and then moved inland. Over time they differentiated into various First Nations peoples, including

4590-624: The exception of the semi-arid climate of the steppe in the south-eastern section, the province has adequate water resources . There are numerous rivers and lakes in Alberta used for swimming, fishing and a range of water sports. There are three large lakes, Lake Claire (1,436 km  [554 sq mi]) in Wood Buffalo National Park, Lesser Slave Lake (1,168 km  [451 sq mi]), and Lake Athabasca (7,898 km  [3,049 sq mi]), which lies in both Alberta and Saskatchewan.

After the British arrival in Canada , approximately half of the province of Alberta, south of the Athabasca River drainage, became part of Rupert's Land which consisted of all land drained by rivers flowing into Hudson Bay . This area was granted by Charles II of England to the Hudson's Bay Company (HBC) in 1670, and rival fur trading companies were not allowed to trade in it. The Athabasca River and

6660-625: 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

6750-461: 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

6840-563: The rivers north of it were not in HBC territory because they drained into the Arctic Ocean instead of Hudson Bay, and they were prime habitats for fur-bearing animals. The first European explorer of the Athabasca region was Peter Pond , who learned of the Methye Portage , which allowed travel from southern rivers into the rivers north of Rupert's Land. Other North American fur traders formed

6930-418: 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

7020-426: The summer months between July and September. The southern and east central parts of Alberta are covered by short prairie grass, which dries up as summer lengthens, to be replaced by hardy perennials such as the prairie coneflower ( Ratibida ), fleabane , and sage ( Artemisia ). Both yellow and white sweet clover ( Melilotus ) can be found throughout the southern and central areas of the province. The trees in

7110-481: The summer, especially in central and southern Alberta. The region surrounding the Calgary–Edmonton Corridor is notable for having the highest frequency of hail in Canada, which is caused by orographic lifting from the nearby Rocky Mountains, enhancing the updraft/downdraft cycle necessary for the formation of hail. In central and northern Alberta the arrival of spring is marked by the early flowering of

7200-415: 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

7290-477: 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

7380-439: The two cities . English is the official language of the province. In 2016, 76.0% of Albertans were anglophone, 1.8% were francophone and 22.2% were allophone . Alberta's economy is based on hydrocarbons , petrochemical industries , livestock and agriculture. The oil and gas industry has been a pillar of Alberta's economy since 1947, when substantial oil deposits were discovered at Leduc No. 1 well. It has also become

7470-497: The unforested part of Alberta is given over either to grain farming or cattle ranching, with mixed farming more common in the north and centre, while ranching and irrigated agriculture predominate in the south. The Alberta badlands are in southeastern Alberta, where the Red Deer River crosses the flat prairie and farmland, and features deep canyons and striking landforms. Dinosaur Provincial Park , near Brooks , showcases

7560-629: The west, Saskatchewan to the east, the Northwest Territories to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada, with Saskatchewan being the other. The eastern part of the province is occupied by the Great Plains , while the western part borders the Rocky Mountains . The province has a predominantly continental climate but experiences quick temperature changes due to air aridity . Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds . Alberta

7650-489: The wooded regions, and pronghorn can be found in the prairies of southern Alberta. Bighorn sheep and mountain goats live in the Rocky Mountains. Rabbits, porcupines , skunks , squirrels, and many species of rodents and reptiles live in every corner of the province. Alberta is home to only one venomous snake species, the prairie rattlesnake . Alberta is home to many large carnivores such as wolves , grizzly bears , black bears , and mountain lions , which are found in

7740-641: 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

7830-452: Was also a territory used by fur traders of the rival companies Hudson's Bay Company and North West Company . The Dominion of Canada bought the lands that would become Alberta as part of the NWT in 1870. From the late 1800s to early 1900s, many immigrants arrived to prevent the prairies from being annexed by the United States. Growing wheat and cattle ranching also became very profitable. In 1905,

7920-569: Was named after Princess Louise Caroline Alberta (1848–1939), the fourth daughter of Queen Victoria . Princess Louise was the wife of John Campbell, Marquess of Lorne , Governor General of Canada (1878–83). Lake Louise and Mount Alberta were also named in her honour. The name "Alberta" is a feminine Latinized form of Albert , the name of Princess Louise's father, the Prince Consort ( cf. Medieval Latin : Albertus , masculine) and its Germanic cognates, ultimately derived from

8010-686: Was part of the French (and Spanish) territory of Louisiana and was sold to the United States in 1803. In the Treaty of 1818 , the portion of Louisiana north of the Forty-Ninth Parallel was ceded to Great Britain. Fur trade expanded in the north, but bloody battles occurred between the rival HBC and NWC, and in 1821 the British government forced them to merge to stop the hostilities. The amalgamated Hudson's Bay Company dominated trade in Alberta until 1870 when

8100-465: Was the homeland of the American bison , also known as buffalo, with its grasses providing pasture and breeding ground for millions of buffalo. The buffalo population was decimated during early settlement, but since then, buffalo have made a comeback, living on farms and in parks all over Alberta. Herbivores are found throughout the province. Moose , mule deer , elk , and white-tailed deer are found in
