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 .

52-698: 54°12′14″N 2°08′02″W  /  54.204°N 2.134°W  / 54.204; -2.134 Langstrothdale is a scenic valley in the Yorkshire Dales in North Yorkshire , England . The uppermost course of the River Wharfe runs through it, but Wharfedale does not begin until the Wharfe meets Cray Gill, downstream of Hubberholme. The name Langstrothdale derives from Old English and translates as 'long marsh' or 'marshy ground'. The dale

104-484: 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

156-414: 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

208-454: 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

260-540: 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

312-694: A major area for caving in the UK. The word dale , like dell , is derived from the Old English word dæl . It has cognates in the Nordic / Germanic words for valley ( dal , tal ), and occurs in valley names across Yorkshire and Northern England. Usage here may have been reinforced by Nordic languages during the time of the Danelaw . Most of the dales are named after their river or stream (e.g., Arkengarthdale , formed by Arkle Beck ). The best-known exception

364-611: A mobile-device software app for those who wish to explore the relevant areas. In this primarily agricultural area, tourism has become an important contributor to the economy. In 2016, there were 3.8 million visits to the Yorkshire Dales National Park including 0.48 million who stayed at least one night. The park authority estimates that this contributed £252 million to the economy and provided 3,583 full-time equivalent jobs. The wider Yorkshire Dales area received 9.7 million visitors who contributed £644 million to

416-410: A monastic route that came over from Ribblesdale into Langstrothdale. The current road westwards through the dale is not a through route to vehicles, ceasing to be a metalled road at High Greenfield ( SD830792 ). The other branch of the road through the dale turns northwards at Beckermonds , to go through Oughtershaw and over Fleet Moss into Sleddale . The long-distance paths, a Pennine Journey , and

468-606: Is Carboniferous Limestone , which is particularly visible in the south-west in features such as Malham Cove . It is overlain in many areas by the Yoredale Series of alternating weak shales and hard limestones and sandstones, which give the dales their characteristic 'stepped' appearance. Most of the dales contain rivers, and the area contains seven primary catchments : the Swale , Ure , Wharfe , Aire , Nidd , Ribble , and Lune . There are several notable cave systems in

520-555: Is Wensleydale , which is named after the small village and former market town of Wensley , rather than the River Ure , although an older name for the dale is Yoredale. River valleys all over Yorkshire are called "(name of river)+ dale "—but only the more northern valleys (and only the upper, rural, reaches) are included in the term "The Dales". The Yorkshire Dales are surrounded by the North Pennines and Orton Fells in

572-487: 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

624-614: 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

676-713: 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

728-828: 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,

780-467: The Dales Way both traverse the dale. The largest conifer forest in the Yorkshire Dales National Park, Greenfield Plantation, was created in upper Langstrothdale between 1968 and 1979. The forest (including a second adjoining plantation known as Cam ), covers an area of 3,000 acres (1,200 hectares), and was made publicly accessible with 7.5 miles (12 km) of bridleways in 2022. Greenfield Plantation

832-593: The Discover England websites, for example, were using the tagline "Discover 'All Creatures Great and Small' in Yorkshire". The dales are U- and V-shaped valleys, the former enlarged and shaped by glaciers , mainly in the most recent Devensian ice age . The underlying rock is mainly Carboniferous Limestone , which results in a large areas of karst topography, in places overlain with shale and sandstone and topped with Millstone Grit , although to

The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains

936-587: The Nidderdale AONB , but without the towns listed above apart from Settle. The lower reaches of Airedale and Wharfedale are not usually included in the area, and Calderdale , south of Airedale and in the South Pennines, is not often considered part of the Dales (even though it is a dale, is in Yorkshire, and its upper reaches are as scenic and rural as many further north). Additionally, although

988-459: The Trip Advisor site include Aysgarth Falls , Malham Cove (scenic walking areas), Ingleborough (hiking trails) and Ribblehead Viaduct . The DalesBus service provides service in the Dales on certain days in summer, "including the Yorkshire Dales National Park and Nidderdale Area of Outstanding Natural Beauty". In summer, these buses supplement the other services operating year-round in

1040-550: The Washburn Valley whose tributary streams and rivers feed into the larger valleys, and Barbondale , Dentdale , Deepdale and Garsdale which feed west to the River Lune . The characteristic scenery of the Dales is green upland pastures separated by dry-stone walls and grazed by sheep and cattle. A survey carried out in 1988 estimated that there were just over 4,971 miles (8,000 km) of dry-stone walling in

1092-653: The ceremonial county of North Yorkshire , but extend into Cumbria and Lancashire ; they are entirely within the historic boundaries of Yorkshire . The majority of the dales are within the Yorkshire Dales National Park , created in 1954. The exception is the area around Nidderdale , which forms the separate Nidderdale Area of Outstanding Natural Beauty . The landscape of the Yorkshire Dales consists of sheltered glacial valleys separated by exposed moorland . The predominant rock

1144-487: The 'Forest of Langstroth'. The dale became part of the lands owned by the Clifford family and in 1604, due to the then Earl of Cumberland's 'extravagances', the lands were sold to pay off his debts. This allowed many Dalesfolk to purchase their own farmsteads. In the age before mass transportation, the road through the dale was part of a packhorse route from Lancaster to Newcastle upon Tyne. Previous to this, it had been

1196-668: The Dales. Tourism in the region declined because of restrictions implemented in relation to the COVID-19 pandemic in 2020, and into 2021. Later in 2021, the volume of visits was expected to increase as a result of the 2020 TV series All Creatures Great and Small , largely filmed within the Dales. The first series aired in the UK in September 2020 and in the US in early 2021. One source stated that visits to Yorkshire websites had increased significantly by late September 2020. By early 2021,

1248-662: The National Park includes the Howgill Fells and Orton Fells, they are not usually considered part of the Dales. Most of the larger southern dales – Ribblesdale, Malhamdale and Airedale, Wharfedale and Nidderdale – run roughly parallel from north to south. The more northerly dales – Wensleydale and Swaledale – run generally from west to east. There are many other smaller or lesser-known dales such as Arkengarthdale , Bishopdale , Clapdale, Coverdale , Kingsdale , Littondale , Langstrothdale , Raydale Waldendale and

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

1352-706: The Yorkshire Dales. Many upland areas consist of heather moorland, used for grouse shooting from 12 August (the Glorious Twelfth ). Much of the rural area is used for agriculture, with residents living in small villages and hamlets or in farmsteads. Miles of dry-stone walls and much of the traditional architecture have remained, including some field barns, though many are no longer in active use. Breeding of sheep and rearing of cattle remain common. To supplement their incomes, many farmers have diversified, with some providing accommodations for tourists. A number of agricultural shows are held each year. Lead mining

1404-537: The area, including the longest system in the United Kingdom, the Three Counties . Agriculture and other land management has significantly affected the appearance of the Dales, through the creation of pastures and meadows for livestock grazing and moorland for red grouse shooting. Dry stone walls and field barns are characteristic of the valley floors, particularly Wensleydale and Swaledale in

1456-406: 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

1508-430: 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

1560-441: 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

1612-697: 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

1820-435: 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

1872-781: 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

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

2028-463: The north and west of the Dent Fault the hills are formed from older Silurian and Ordovician rocks. The underlying limestone in parts of the Dales has extensive cave systems, including the 54-mile-long (87 km) Three Counties System , making it a major area for caving in the UK. There are over 2500 known caves; some are open to the public for tours. Visitors can try caving at one of

2184-418: 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

2236-631: 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

2288-461: 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

2340-476: The show caves: White Scar Cave, Ingleborough Cave or Stump Cross Caverns near Greenhow. The systems include: 54°16′N 2°05′W  /  54.267°N 2.083°W  / 54.267; -2.083 Drainage basin 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

2392-418: 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

2444-415: 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

2496-477: 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

2548-673: 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

2704-421: Was first colonised by Anglians in the seventh century, with Norse invaders arriving later. In Norman times, many of the isolated settlements were allowed to remain, but were prevented from expanding by an arcane ruling known as the 'Forest Law'. At that time, Langstrothdale was well forested, and the upper northern part of the dale (which is now moorland) was a royal hunting forest known as Langstrothdale Chase or as
