In layman's terms, the shield was divided horizontally into red and gold, the upper half depicting a Griqua hunter holding a slain buck and

357-582: A lake , an ocean , or another river. A stream refers to water that flows in a natural channel , a geographic feature that can contain flowing water. A stream may also be referred to as a watercourse. The study of the movement of water as it occurs on Earth is called hydrology , and their effect on the landscape is covered by geomorphology . Rivers are part of the water cycle , the continuous processes by which water moves about Earth. This means that all water that flows in rivers must ultimately come from precipitation . The sides of rivers have land that

476-547: A trip hammer , and grind grains with a millstone . In the Middle Ages , water mills began to automate many aspects of manual labor , and spread rapidly. By 1300, there were at least 10,000 mills in England alone. A medieval watermill could do the work of 30–60 human workers. Water mills were often used in conjunction with dams to focus and increase the speed of the water. Water wheels continued to be used up to and through

595-484: A bisecting route leading from Kokstad to Underberg (109 km), Swartberg (41 km) and Bulwer (147 km). The N2, the national route, leads from Kokstad to the east to Port Shepstone (175 km), Durban (380 km) and to the south Mount Ayliff (57 km), Mthatha (180 km), East London (419 km) and Qonce (447 km). Kokstad is 10 km from the Eastern Cape border on

714-740: A boat along certain stretches. In these religions, such as that of the Altai in Russia , the river is considered a living being that must be afforded respect. Rivers are some of the most sacred places in Hinduism. There is archeological evidence that mass ritual bathing in rivers at least 5,000 years ago in the Indus river valley . While most rivers in India are revered, the Ganges is most sacred. The river has

833-515: A central role in various Hindu myths, and its water is said to have properties of healing as well as absolution from sins. Hindus believe that when the cremated remains of a person is released into the Ganges, their soul is released from the mortal world. Freshwater fish make up 40% of the world's fish species, but 20% of these species are known to have gone extinct in recent years. Human uses of rivers make these species especially vulnerable. Dams and other engineered changes to rivers can block

952-408: A continuous flow of water throughout the year. This may be because an arid climate is too dry depending on the season to support a stream, or because a river is seasonally frozen in the winter (such as in an area with substantial permafrost ), or in the headwaters of rivers in mountains, where snowmelt is required to fuel the river. These rivers can appear in a variety of climates, and still provide

1071-564: A habitat for aquatic life and perform other ecological functions. Subterranean rivers may flow underground through flooded caves. This can happen in karst systems, where rock dissolves to form caves. These rivers provide a habitat for diverse microorganisms and have become an important target of study by microbiologists . Other rivers and streams have been covered over or converted to run in tunnels due to human development. These rivers do not typically host any life, and are often used only for stormwater or flood control. One such example

1190-495: A large scale. This has been attributed to unusually large floods destroying infrastructure; however, there is evidence that permanent changes to climate causing higher aridity and lower river flow may have been the determining factor in what river civilizations succeeded or dissolved. Water wheels began to be used at least 2,000 years ago to harness the energy of rivers. Water wheels turn an axle that can supply rotational energy to move water into aqueducts , work metal using

1309-518: A lower elevation , such as an ocean , lake , or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons. Rivers are regulated by the water cycle , the processes by which water moves around the Earth. Water first enters rivers through precipitation , whether from rainfall, the runoff of water down a slope, the melting of glaciers or snow , or seepage from aquifers beneath

1428-479: A more suitable place on the banks of the Mzimhlava river . Two prominent European settlers George Brisley and Donald Strachan played a major role in the early development of Kokstad and East Griqualand: their trading store, Strachan and Co, in 1874 introduced South Africa's first indigenous currency—a set of trade tokens which circulated across a wide region, covering an area the size of Ireland. Confirmation that

1547-556: A peak in the 1970s, when between two or three dams were completed every day, and has since begun to decline. New dam projects are primarily focused in China , India , and other areas in Asia . The first civilizations of Earth were born on floodplains between 5,500 and 3,500 years ago. The freshwater, fertile soil, and transportation provided by rivers helped create the conditions for complex societies to emerge. Three such civilizations were

1666-409: A rifle and facing a lion, and the lower half a yoke above an upright black cannon barrel, the whole design surrounded by a border divided into forty sections alternately silver and black. The crest was a cock's head issuing from a golden eastern crown, and the motto was Pro rege lege et grege . Drakensberg The Drakensberg ( Zulu : uKhahlamba, Sotho : Maloti, Afrikaans : Drakensberge)

1785-891: A ritualistic sense has been compared to the Christian ritual of baptism , famously the Baptism of Jesus in the Jordan River . Floods also appear in Norse mythology , where the world is said to emerge from a void that eleven rivers flowed into. Aboriginal Australian religion and Mesoamerican mythology also have stories of floods, some of which contain no survivors, unlike the Abrahamic flood. Along with mythological rivers, religions have also cared for specific rivers as sacred rivers. The Ancient Celtic religion saw rivers as goddesses. The Nile had many gods attached to it. The tears of

1904-425: A river can take several forms. Tidal rivers (often part of an estuary ) have their levels rise and fall with the tide . Since the levels of these rivers are often already at or near sea level, the flow of alluvium and the brackish water that flows in these rivers may be either upriver or downriver depending on the time of day. Rivers that are not tidal may form deltas that continuously deposit alluvium into

2023-756: A river such as fish , aquatic plants , and insects have different roles, including processing organic matter and predation . Rivers have produced abundant resources for humans, including food , transportation , drinking water , and recreation. Humans have engineered rivers to prevent flooding, irrigate crops, perform work with water wheels , and produce hydroelectricity from dams. People associate rivers with life and fertility and have strong religious, political, social, and mythological attachments to them. Rivers and river ecosystems are threatened by water pollution , climate change , and human activity. The construction of dams, canals , levees , and other engineered structures has eliminated habitats, has caused

2142-714: A rock shelter wall in the Ginsberg dates back about 2400 years... paint chips at least a thousand years older have also been found." The site also indicates that "[t]he rock art of the Drakensberg is the largest and most concentrated group of rock paintings in Africa south of the Sahara, and is outstanding both in quality and diversity of subject." River A river is a natural freshwater stream that flows on land or inside caves towards another body of water at

2261-460: A section of the river behind them into a lake or reservoir. This can provide nearby cities with a predictable supply of drinking water. Hydroelectricity is desirable as a form of renewable energy that does not require any inputs beyond the river itself. Dams are very common worldwide, with at least 75,000 higher than 6 feet (1.8 m) in the U.S. Globally, reservoirs created by dams cover 193,500 square miles (501,000 km ). Dam-building reached

2380-450: A suitable spring further down the mountain (Crystal Springs), he first conducted a series of water flow rate metering, to establish there was sufficient flow to meet the town's needs. Once it had been proven there was sufficient flow, Mail then oversaw design and construction of a new water treatment plant. The new plant provided crystal clear water to Kokstad, which helped the town grow and flourish. In addition to supplying drinking water to

2499-438: A water body is that body's riparian zone . Plants in the riparian zone of a river help stabilize its banks to prevent erosion and filter alluvium deposited by the river on the shore, including processing the nitrogen and other nutrients it contains. Forests in a riparian zone also provide important animal habitats . River ecosystems have also been categorized based on the variety of aquatic life they can sustain, also known as

2618-445: Is a tributary , and the place they meet is a confluence . Rivers must flow to lower altitudes due to gravity . The bed of a river is typically within a river valley between hills or mountains . Rivers flowing through an impermeable section of land such as rocks will erode the slopes on the sides of the river. When a river carves a plateau or a similar high-elevation area, a canyon can form, with cliffs on either side of

2737-504: Is also important for the lumber industry , as logs can be shipped via river. Countries with dense forests and networks of rivers like Sweden have historically benefited the most from this method of trade. The rise of highways and the automobile has made this practice less common. One of the first large canals was the Canal du Midi , connecting rivers within France to create a path from

2856-564: Is an ancient dam built on the Nile 4,500 years ago. The Ancient Roman civilization used aqueducts to transport water to urban areas . Spanish Muslims used mills and water wheels beginning in the seventh century. Between 130 and 1492, larger dams were built in Japan, Afghanistan, and India, including 20 dams higher than 15 metres (49 ft). Canals began to be cut in Egypt as early as 3000 BC, and

2975-448: Is at a higher elevation than the river itself, and in these areas, water flows downhill into the river. The headwaters of a river are the smaller streams that feed a river, and make up the river's source. These streams may be small and flow rapidly down the sides of mountains . All of the land uphill of a river that feeds it with water in this way is in that river's drainage basin or watershed. A ridge of higher elevation land

3094-405: Is because any natural impediment to the flow of the river may cause the current to deflect in a different direction. When this happens, the alluvium carried by the river can build up against this impediment, redirecting the course of the river. The flow is then directed against the opposite bank of the river, which will erode into a more concave shape to accommodate the flow. The bank will still block

3213-453: Is correlated with and thus can be used to predict certain data points related to rivers, such as the size of the drainage basin (drainage area), and the length of the channel. The ecosystem of a river includes the life that lives in its water, on its banks, and in the surrounding land. The width of the channel of a river, its velocity, and how shaded it is by nearby trees. Creatures in a river ecosystem may be divided into many roles based on

3332-610: Is due to a failed westerly branch of the main rift that caused Antarctica to start drifting away from southern Africa during the breakup of Gondwana about 150 million years ago. The lower Limpopo River and Save River drain into the Indian Ocean through what remains of this relict incipient rift valley, which now forms part of the South African Lowveld . During the past 20 million years, southern Africa has experienced massive uplifting, especially in

3451-493: Is fed by the pure water of Crystal Springs, the main source of Kokstad's water supply. In 1924, William Mortimer Mail (b. 16 November 1885) was to take-up an appointment as the Kokstad Town Engineer, Arguably, Mail's most notable achievement was improvement to Kokstad's drinking water, which at the time of his arrival, was drawn from a mountain stream. Whenever it rained, it became heavily stained. After identifying

3570-549: Is formed by slightly younger Beaufort rocks (250 million years old) that also are part of the Karoo Supergroup. The Ecca and Beaufort groups are composed of sedimentary rocks that are less erosion resistant than the other rocks that make up the Drakensberg escarpment. Therefore, this portion of escarpment is not so impressive as the Mpumalanga and Lesotho stretches of the Drakensberg. The Drakensberg that form

3689-727: Is home to large herds of grazing fauna and antelopes such as eland (Taurotragus oryx) , reedbuck (Redunca arundinum) , mountain reedbuck (Redunca fulvorufula) , grey rhebok (Pelea capreolus) , and even some oribi (Ourebia ourebi) . Chacma baboons also are present. Endemic species include a large number of chameleons and other reptiles. There is one endemic frog, the forest rain frog ( Breviceps sylvestris ) , and four more species that are found mainly in these mountains; long-toed tree frog ( Leptopelis xenodactylus ) , plaintive rain frog ( Breviceps maculatus ) , rough rain frog ( Breviceps verrucosus ) , and Poynton's caco ( Cacosternum poyntoni ) . The high slopes are hard to reach so

3808-497: Is in part because of a projected loss of snowpack in mountains, meaning that melting snow can't replenish rivers during warm summer months, leading to lower water levels. Lower-level rivers also have warmer temperatures, threatening species like salmon that prefer colder upstream temperatures. Attempts have been made to regulate the exploitation of rivers to preserve their ecological functions. Many wetland areas have become protected from development. Water restrictions can prevent

3927-814: Is known as 'Klein Drakensberg' by the Afrikaner . From Hoedspruit it extends west to Tzaneen , also in Limpopo Province , where it is known as the Wolkberg Mountains and Iron Crown Mountain. At 2,200 m (7,200 ft) above sea level, the Wolkberg is the highest elevation in Limpopo. The escarpment extends west again and at Mokopane it is known as the Strydpoort Mountains. The Afrikaans name Drakensberge comes from

4046-402: Is part of permafrost ice caps, or trace amounts of water vapor in the atmosphere. However, there is evidence that rivers flowed on Mars for at least 100,000 years. The Hellas Planitia is a crater left behind by an impact from an asteroid. It has sedimentary rock that was formed 3.7 billion years ago, and lava fields that are 3.3 billion years old. High resolution images of the surface of

4165-671: Is part of the Transvaal Supergroup, which also forms the Magaliesberg to the north and northwest of Pretoria. These rocks are more than 2000 million years old. South of the 26°S parallel the Drakensberg escarpment is composed of Ecca shales , which belong to the Karoo Supergroup , and they are 300 million years old. The portion of the Drakensberg that forms the KwaZulu-Natal – Free State border

4284-633: Is rarely static, the exact location of a river border may be called into question by countries. The Rio Grande between the United States and Mexico is regulated by the International Boundary and Water Commission to manage the right to fresh water from the river, as well as mark the exact location of the border. Up to 60% of fresh water used by countries comes from rivers that cross international borders. This can cause disputes between countries that live upstream and downstream of

4403-701: Is that of the Mississippi River , whose drainage basin covers 40% of the contiguous United States . The river was then used for shipping crops from the American Midwest and cotton from the American South to other states as well as the Atlantic Ocean. The role of urban rivers has evolved from when they were a center of trade, food, and transportation to modern times when these uses are less necessary. Rivers remain central to

4522-553: Is the Sunswick Creek in New York City, which was covered in the 1800s and now exists only as a sewer-like pipe. While rivers may flow into lakes or man-made features such as reservoirs , the water they contain will always tend to flow down toward the ocean . However, if human activity siphons too much water away from a river for other uses, the riverbed may run dry before reaching the sea. The outlets mouth of

4641-635: Is the eastern portion of the Great Escarpment , which encloses the central Southern African plateau. The Great Escarpment reaches its greatest elevation – 2,000 to 3,482 metres (6,562 to 11,424 feet) within the border region of South Africa and Lesotho . The Drakensberg escarpment stretches for more than 1,000 kilometres (600 miles) from the Eastern Cape Province in the South, then successively forms, in order from south to north,

4760-538: Is the largest private reserve adjoining the World Heritage Site and is found in the accessible Kamberg area, the heart of the historic San (Bushman) painting region of the Ukhahlamba. The grassland of the lower slopes has been greatly affected by agriculture, however, especially by overgrazing . Nearly all of the original grassland and forest has disappeared and more protection is needed, although

4879-563: Is unknown. The KwaZulu-Natal – Free State Drakensberg are composed of softer rocks and therefore have a more rounded, softer appearance from below. Generally, the top of the escarpment is almost table-top flat and smooth, even in Lesotho. The "Lesotho Mountains" are formed away from the Drakensberg escarpment by erosion gulleys which turn into deep valleys containing tributaries of the Orange River . The large number of such tributaries give

4998-842: Is what typically separates drainage basins; water on one side of a ridge will flow into one set of rivers, and water on the other side will flow into another. One example of this is the Continental Divide of the Americas in the Rocky Mountains . Water on the western side of the divide flows into the Pacific Ocean , whereas water on the other side flows into the Atlantic Ocean . Not all precipitation flows directly into rivers; some water seeps into underground aquifers . These, in turn, can still feed rivers via

5117-599: The 2024 Summer Olympics . Another example is the restoration of the Isar in Munich from being a fully canalized channel with hard embankments to being wider with naturally sloped banks and vegetation. This has improved wildlife habitat in the Isar, and provided more opportunities for recreation in the river. As a natural barrier , rivers are often used as a border between countries , cities, and other territories . For example,

5236-487: The Atlantic Ocean to the Mediterranean Sea . The nineteenth century saw canal-building become more common, with the U.S. building 4,400 miles (7,100 km) of canals by 1830. Rivers began to be used by cargo ships at a larger scale, and these canals were used in conjunction with river engineering projects like dredging and straightening to ensure the efficient flow of goods. One of the largest such projects

5355-648: The Drakensberg into a region earlier devastated by the great Zulu King, Shaka—thus its name "Nomansland". By the time the Griquas arrived in their new promised land eighteen months later they were exhausted and most of their livestock had perished. The impoverished Griquas named the mountain where they settled Mount Currie after Sir Walter Currie who gave support to their effort to settle here. Once settled their leader, Adam Kok, renamed their new land East Griqualand. Every male Griqua who settled in East Griqualand

5474-542: The Drakensberg montane grasslands, woodlands, and forests ecoregion. The mountains are rich in plant life, including a large number of species listed in the Red Data Book of threatened plants, with 119 species listed as globally endangered and "of the 2 153 plant species in the park, a remarkable 98 are endemic or near-endemic". The flora of the high alti-montane grasslands is mainly tussock grass , creeping plants, and small shrubs such as ericas . These include

5593-585: The Giant's Castle reserve is a haven for the eland and also is a breeding ground for the bearded vulture . 5.81% of the Drakensberg montane grasslands, woodlands and forests ecoregion is in protected areas. These include Kruger National Park , Mountain Zebra National Park , Golden Gate Highlands National Park, Camdeboo National Park , Sehlabathebe National Park, and Tsehlanyane National Park. The Maloti-Drakensberg Transfrontier Conservation Area

5712-501: The Industrial Revolution as a source of power for textile mills and other factories, but were eventually supplanted by steam power . Rivers became more industrialized with the growth of technology and the human population . As fish and water could be brought from elsewhere, and goods and people could be transported via railways , pre-industrial river uses diminished in favor of more complex uses. This meant that

5831-791: The Lamari River in New Guinea separates the Angu and the Fore people in New Guinea. The two cultures speak different languages and rarely mix. 23% of international borders are large rivers (defined as those over 30 meters wide). The traditional northern border of the Roman Empire was the Danube , a river that today forms the border of Hungary and Slovakia . Since the flow of a river

5950-534: The Lesotho Highlands a very rugged mountainous appearance, both from the ground and from the air. The higher parts of Drakensberg have a mildly periglacial environment . It is possible that recent climate change has diminished the intensity of periglaciation. Knight and Grab mapped out the distribution of lightning strikes in the Drakensburg and discovered that lightning significantly controls

6069-475: The Magaliesberg . The high treeless peaks of the Drakensberg (from 2,500 m (8,200 ft) upward) have been described by the World Wide Fund for Nature as the Drakensberg alti-montane grasslands and woodlands ecoregion . These steep slopes are the most southerly high mountains in Africa, and being farther from the equator provide cooler habitats at lower elevations than most mountain ranges on

6188-525: The Nile and the Ganges . The Quran describes these four rivers as flowing with water, milk, wine, and honey, respectively. The book of Genesis also contains a story of a great flood . Similar myths are present in the Epic of Gilgamesh , Sumerian mythology, and in other cultures. In Genesis, the flood's role was to cleanse Earth of the wrongdoing of humanity. The act of water working to cleanse humans in

6307-568: The River Continuum Concept . "Shredders" are organisms that consume this organic material. The role of a "grazer" or "scraper" organism is to feed on the algae that collects on rocks and plants. "Collectors" consume the detritus of dead organisms. Lastly, predators feed on living things to survive. The river can then be modeled by the availability of resources for each creature's role. A shady area with deciduous trees might experience frequent deposits of organic matter in

6426-627: The River Lethe to forget their previous life. Rivers also appear in descriptions of paradise in Abrahamic religions , beginning with the story of Genesis . A river beginning in the Garden of Eden waters the garden and then splits into four rivers that flow to provide water to the world. These rivers include the Tigris and Euphrates , and two rivers that are possibly apocryphal but may refer to

6545-787: The Sumerians in the Tigris–Euphrates river system , the Ancient Egyptian civilization in the Nile, and the Indus Valley Civilization on the Indus River . The desert climates of the surrounding areas made these societies especially reliant on rivers for survival, leading to people clustering in these areas to form the first cities . It is also thought that these civilizations were the first to organize

6664-485: The climate . The alluvium carried by rivers, laden with minerals, is deposited into the floodplain when the banks spill over, providing new nutrients to the soil, allowing them to support human activity like farming as well as a host of plant and animal life. Deposited sediment from rivers can form temporary or long-lasting fluvial islands . These islands exist in almost every river. About half of all waterways on Earth are intermittent rivers , which do not always have

6783-685: The cultural identity of cities and nations. Famous examples include the River Thames 's relationship to London , the Seine to Paris , and the Hudson River to New York City . The restoration of water quality and recreation to urban rivers has been a goal of modern administrations. For example, swimming was banned in the Seine for over 100 years due to concerns about pollution and the spread of E. coli , until cleanup efforts to allow its use in

6902-424: The discharge of a river, the amount of water passing through it at a particular time. The flow of a river can act as a means of transportation for plant and animal species, as well as a barrier. For example, the Amazon River is so wide in parts that the variety of species on either side of its basin are distinct. Some fish may swim upstream to spawn as part of a seasonal migration . Species that travel from

7021-465: The extinction of some species, and lowered the amount of alluvium flowing through rivers. Decreased snowfall from climate change has resulted in less water available for rivers during the summer. Regulation of pollution, dam removal , and sewage treatment have helped to improve water quality and restore river habitats. A river is a natural flow of freshwater that flows on or through land towards another body of water downhill. This flow can be into

7140-436: The sea . The sediment yield of a river is the quantity of sand per unit area within a watershed that is removed over a period of time. The monitoring of the sediment yield of a river is important for ecologists to understand the health of its ecosystems, the rate of erosion of the river's environment, and the effects of human activity. Rivers rarely run in a straight direction, instead preferring to bend or meander . This

7259-414: The uKhahlamba Drakensberg Park was listed by UNESCO in 2000 as a World Heritage site. The park also is in the List of Wetlands of International Importance (under the Ramsar Convention ). The Royal Natal National Park , which contains some of the higher peaks, is part of this large park complex. Adjacent to the Ukhahlamba Drakensberg World Heritage Site is the 1900 ha Allendale Mountain Reserve, which

7378-521: The water table , the groundwater beneath the surface of the land stored in the soil . Water flows into rivers in places where the river's elevation is lower than that of the water table. This phenomenon is why rivers can still flow even during times of drought . Rivers are also fed by the melting of snow glaciers present in higher elevation regions. In summer months, higher temperatures melt snow and ice, causing additional water to flow into rivers. Glacier melt can supplement snow melt in times like

7497-612: The Drakensberg Royal Natal National Park and Bushman's Nek. Due to the materials used in their production, these paintings are difficult to date, but there is anthropological evidence, including many hunting implements, that the San people existed in the Drakensberg at least 40,000 years ago, and possibly more than 100,000 years ago. According to mountainsides.co.za, "[i]n Nd edema Gorge in the Central Ginsberg 3,900 paintings have been recorded at 17 sites. One of them, Sebaayeni Cave, contains 1,146 individual paintings." The website, south Africa.info, indicates that although "the oldest painting on

They moved because of the growing confrontation they faced with the Voortrekkers who had moved north of the Orange River to escape the laws of the British. The Voortrekkers, largely Dutch, secured leases over Griqua land and then refused to return the land at the end of the lease. The Big Hole of Kimberley was at the centre of controversy over one such lease. The Griquas were forced to travel over

7854-511: The Drakensberg, two of which are highly venomous. One bird is endemic to the high peaks, the mountain pipit (Anthus hoeschi) , and another six species are found mainly here: Bush blackcap (Lioptilus nigricapillus) , buff-streaked chat (Oenanthe bifasciata) , Rudd's lark (Heteromirafra ruddi) , Drakensberg rockjumper (Chaetops aurantius) , yellow-breasted pipit (Anthus chloris) , and Drakensberg siskin (Serinus symonsi) . The endangered Cape vulture and lesser kestrel are two of

It is a farming community with majority of its countryside land being cattle farms or residential farms. In 1820 the Griqua tribe which lived in Griquatown (in central South Africa) split and under the leadership of Adam Kok III, descendant of the former cook who established the tribe, one section first moved to Philippolis (southern Free State). In 1861 several hundred Griquas moved across

8211-420: The Strachan and Co coins circulated as money in the region at this time comes from the local Standard Bank at Kokstad and the managing director of Strachan and Co. In 1878 East Griqualand came into the possession of Cape Colony. The first hotel in Kokstad, The Royal, was opened by an African-American who also started a newspaper (the Kokstad Advertiser ) in 1881. Kokstad became a municipality in 1892. In 1904

Other endemic species include three frogs found in the mountain streams, Drakensberg river frog (Amietia dracomontana) , Phofung river frog ( Amietia vertebralis ) , and Maluti river frog (Amietia umbraculata) . Fish are found in

8568-695: The bodies of humans and animals worldwide, as well as in the soil, with potentially negative health effects. Research into how to remove it from the environment, and how harmful exposure is, is ongoing. Fertilizer from farms can lead to a proliferation of algae on the surface of rivers and oceans, which prevents oxygen and light from dissolving into water, making it impossible for underwater life to survive in these so-called dead zones . Urban rivers are typically surrounded by impermeable surfaces like stone, asphalt , and concrete. Cities often have storm drains that direct this water to rivers. This can cause flooding risk as large amounts of water are directed into

8687-623: The border between Lesotho and the Eastern Cape and the border between Lesotho and KwaZulu-Natal Province . Thereafter it forms the border between KwaZulu-Natal and the Free State , and next as the border between KwaZulu-Natal and Mpumalanga Province . The escarpment winds north from there, through Mpumalanga, where it includes features such as the Blyde River Canyon , Three Rondavels , and God's Window . It then extends farther north to Hoedspruit in southeastern Limpopo where it

8806-405: The complete draining of rivers. Limits on the construction of dams, as well as dam removal , can restore the natural habitats of river species. Regulators can also ensure regular releases of water from dams to keep animal habitats supplied with water. Limits on pollutants like pesticides can help improve water quality. Today, the surface of Mars does not have liquid water. All water on Mars

8925-530: The continent. High rainfall generates many mountain streams and rivers, including the sources of the Orange River , southern Africa's longest, and the Tugela River . These mountains also have the world's highest waterfall, the Tugela Falls (Thukela Falls), which has a total drop of 947 m (3,107 ft) (Venezuela's Angel Falls is also a candidate for highest waterfall). The rivers that run from

9044-582: The easily eroded sandstone of Clarens Formation , the layer below the thick, hard basalt layer on the KwaZulu Natal-Lesotho border. Many of these caves have paintings by the San (Bushmen). This portion of the Drakensberg has between 35,000 and 40,000 works of San rock art , and is the largest collection of such parietal work in the world. Some 20,000 individual rock paintings have been recorded at 500 different caves and overhanging sites between

9163-411: The east, with the result that most of the plateau lies above 1,000 m (3,300 ft) despite extensive erosion. The plateau is tilted such that it is highest in the east and slopes gently downward toward the west and south. Typically, the elevation of the edge of the eastern escarpments is in excess of 2,000 m (6,600 ft). It reaches its highest point of over 3,000 m (9,800 ft) where

9282-436: The effect of normalizing the effects of rivers; the greatest floods are smaller and more predictable, and larger sections are open for navigation by boats and other watercraft. A major effect of river engineering has been a reduced sediment output of large rivers. For example, the Mississippi River produced 400 million tons of sediment per year. Due to the construction of reservoirs , sediment buildup in man-made levees , and

9401-711: The environment is fairly undamaged. However, tourism in the Drakensberg is developing, with a variety of hiking trails , hotels, and resorts appearing on the slopes. Much of the higher South African parts of the range have been designated as game reserves or wilderness areas . 7% of the Drakensberg alti-montane grasslands and woodlands ecoregion is in protected areas. These include Golden Gate Highlands National Park , Sehlabathebe National Park , Tsehlanyane National Park , Malekgalonyane Nature Reserve , Giant's Castle Game Reserve , Loteni Nature Reserve , Natal National Park , Vergelegen Nature Reserve , Beaumont Nature Reserve , and Lammergeier Highlands Nature Reserve . Of these

9520-631: The escarpment forms part of the international border between Lesotho and the South African province of KwaZulu-Natal . The escarpment seen from below resembles a range of mountains. The Limpopo, Mpumalanga, and Lesotho Drakensberg have hard erosion-resistant upper surfaces and therefore have a very rugged appearance, combining steep-sided blocks and pinnacles (giving rise to the Zulu name "Barrier of up-pointed spears"). Who first gave these mountains their Afrikaans or Dutch name Drakensberg , and why,

9639-499: The evolution of the mountain landscapes because it helps to shape the summit areas – the highest areas – with this blasting effect. Previously, angular debris was presumed to have been created by changes typical of cold, periglacial environments, such as fracturing due to frost. The geological composition of Drakensberg (escarpment wall) varies considerably along its more than 1000 km length. The Limpopo and Mpumalanga Drakensberg are capped by an erosion resistant quartzite layer that

9758-451: The fish zonation concept. Smaller rivers can only sustain smaller fish that can comfortably fit in its waters, whereas larger rivers can contain both small fish and large fish. This means that larger rivers can host a larger variety of species. This is analogous to the species-area relationship , the concept of larger habitats being host to more species. In this case, it is known as the species-discharge relationship, referring specifically to

9877-673: The floating of wood on rivers to transport it, was especially important. Rivers also were an important source of drinking water . For civilizations built around rivers, fish were an important part of the diet of humans. Some rivers supported fishing activities, but were ill-suited to farming, such as those in the Pacific Northwest . Other animals that live in or near rivers like frogs , mussels , and beavers could provide food and valuable goods such as fur . Humans have been building infrastructure to use rivers for thousands of years. The Sadd el-Kafara dam near Cairo , Egypt,

9996-412: The flow of the river beneath its surface. These help rivers flow straighter by increasing the speed of the water at the middle of the channel, helping to control floods. Levees are also used for this purpose. They can be thought of as dams constructed on the sides of rivers, meant to hold back water from flooding the surrounding area during periods of high rainfall. They are often constructed by building up

10115-399: The flow, causing it to reflect in the other direction. Thus, a bend in the river is created. Rivers may run through low, flat regions on their way to the sea. These places may have floodplains that are periodically flooded when there is a high level of water running through the river. These events may be referred to as "wet seasons' and "dry seasons" when the flooding is predictable due to

10234-650: The form of leaves. In this type of ecosystem, collectors and shredders will be most active. As the river becomes deeper and wider, it may move slower and receive more sunlight . This supports invertebrates and a variety of fish , as well as scrapers feeding on algae. Further downstream, the river may get most of its energy from organic matter that was already processed upstream by collectors and shredders. Predators may be more active here, including fish that feed on plants, plankton , and other fish. The flood pulse concept focuses on habitats that flood seasonally, including lakes and marshes . The land that interfaces with

10353-508: The goddess Isis were said to be the cause of the river's yearly flooding, itself personified by the goddess Hapi . Many African religions regard certain rivers as the originator of life. In Yoruba religion , Yemọja rules over the Ogun River in modern-day Nigeria and is responsible for creating all children and fish. Some sacred rivers have religious prohibitions attached to them, such as not being allowed to drink from them or ride in

10472-422: The highest part of Drakensberg the composition of the flora is independent on slope aspect (direction) and varies, depending on the hardness of the rock clasts . This hardness is related to weathering and is variable even within a single landform . The Drakensberg area is "home to 299 recorded bird species"' making up "37% of all non-marine avian species in southern Africa". There are 24 species of snakes in

10591-428: The irrigation of desert environments for growing food. Growing food at scale allowed people to specialize in other roles, form hierarchies, and organize themselves in new ways, leading to the birth of civilization. In pre-industrial society , rivers were a source of transportation and abundant resources. Many civilizations depended on what resources were local to them to survive. Shipping of commodities, especially

10710-440: The landscape around it, forming deltas and islands where the flow slows down. Rivers rarely run in a straight line, instead, they bend or meander ; the locations of a river's banks can change frequently. Rivers get their alluvium from erosion , which carves rock into canyons and valleys . Rivers have sustained human and animal life for millennia, including the first human civilizations . The organisms that live around or in

10829-434: The late summer, when there may be less snow left to melt, helping to ensure that the rivers downstream of the glaciers have a continuous supply of water. Rivers flow downhill, with their direction determined by gravity . A common misconception holds that all or most rivers flow from North to South, but this is not true. As rivers flow downstream, they eventually merge to form larger rivers. A river that feeds into another

10948-474: The level of river branching in a drainage basin. Several systems of stream order exist, one of which is the Strahler number . In this system, the first tributaries of a river are 1st order rivers. When two 1st order rivers merge, the resulting river is 2nd order. If a river of a higher order and a lower order merge, the order is incremented from whichever of the previous rivers had the higher order. Stream order

11067-561: The local ecosystems of rivers needed less protection as humans became less reliant on them for their continued flourishing. River engineering began to develop projects that enabled industrial hydropower , canals for the more efficient movement of goods, as well as projects for flood prevention . River transportation has historically been significantly cheaper and faster than transportation by land. Rivers helped fuel urbanization as goods such as grain and fuel could be floated downriver to supply cities with resources. River transportation

11186-595: The many rivers and streams, including the Maluti redfin ( Pseudobarbus quathlambae ) that was thought to be extinct before being found in the Senqunyane River in Lesotho. The lower slopes of the Drakensberg support much wildlife, perhaps most importantly the rare southern white rhinoceros (which was nurtured here when facing extinction) and the black wildebeest ( Connochaetes gnou , which as of 2011 only thrives in protected areas and game reserves). The area

11305-407: The mechanical shadoof began to be used to raise the elevation of water. Drought years harmed crop yields, and leaders of society were incentivized to ensure regular water and food availability to remain in power. Engineering projects like the shadoof and canals could help prevent these crises. Despite this, there is evidence that floodplain-based civilizations may have been abandoned occasionally at

11424-400: The migration routes of fish and destroy habitats. Rivers that flow freely from headwaters to the sea have better water quality, and also retain their ability to transport nutrient-rich alluvium and other organic material downstream, keeping the ecosystem healthy. The creation of a lake changes the habitat of that portion of water, and blocks the transportation of sediment, as well as preventing

11543-636: The name the earliest Dutch settlers gave to the escarpment, namely Drakensbergen , or Dragons' Mountains . The highest portion of the Great Escarpment is known in Zulu as uKhahlamba and as Maloti in Sotho ("Barrier of up-pointed spears"). The Great Escarpment is composed of steep rift valley walls formed around a bulging of continental crust during the breakup of southern Gondwana that have since eroded inland from their original positions near

11662-399: The natural meandering of the river. Dams block the migration of fish such as salmon for which fish ladder and other bypass systems have been attempted, but these are not always effective. Pollution from factories and urban areas can also damage water quality. " Per- and polyfluoroalkyl substances (PFAS) is a widely used chemical that breaks down at a slow rate. It has been found in

11781-429: The natural terrain with soil or clay. Some levees are supplemented with floodways, channels used to redirect floodwater away from farms and populated areas. Dams restrict the flow of water through a river. They can be built for navigational purposes, providing a higher level of water upstream for boats to travel in. They may also be used for hydroelectricity , or power generation from rivers. Dams typically transform

11900-935: The northeastern and eastern borders of Lesotho, as well as the Eastern Cape Drakensberg, are composed of a thick layer of basalt (lava) that erupted 180 million years ago. That layer rests on the youngest of the Karoo Supergroup sediments, the Clarens sandstone , which was laid down under desert conditions, about 200 million years ago. The highest peak is Thabana Ntlenyana , at 3,482 m (11,424 ft). Other notable peaks include Mafadi (3,450 m (11,319 ft)), Makoaneng at 3,416 metres (11,207 ft), Njesuthi at 3,408 metres (11,181 ft), Champagne Castle at 3,377 metres (11,079 ft), Giant's Castle at 3,315 metres (10,876 ft), Ben Macdhui at 3,001 metres (9,846 ft), and Popple Peak at 3,331 metres (10,928 ft), all of these are in

12019-425: The plain show evidence of a river network, and even river deltas. These images reveal channels formed in the rock, recognized by geologists who study rivers on Earth as being formed by rivers, as well as "bench and slope" landforms, outcroppings of rock that show evidence of river erosion. Not only do these formations suggest that rivers once existed, but that they flowed for extensive time periods, and were part of

12138-577: The population was recorded at 2903 whom a third were Griquas. The town was transferred to Natal province in 1978. Today the population of Kokstad lies at just over 50,000 people. Stemming from a relatively old farming community, Kokstad rose from the lands beneath Mount Currie. Many old buildings and monuments have been erected that are now considered to be National Heritage Sites. The area is popular for its many rivers and dams that provide ample opportunity for trout fishing and hiking possibilities. There are three reserves, Mount Currie, Wilfred Bauer and

12257-600: The rare Spiral Aloe ( Aloe polyphylla ) , which as its name suggests, has leaves with a spiral shape. Meanwhile, the lower slopes are mainly grassland, but are also home to conifers , which are rare in Africa, the species of conifer found in the Drakensberg belong to the genus Podocarpus . The grassland is of interest as it contains a great number of endemic plants. Grasses found here include oat grass Monocymbium ceresiiforme , Diheteropogon filifolius , Sporobolus centrifugus , caterpillar grass ( Harpochloa falx ) , Cymbopogon dieterlenii , and Eulalia villosa . In

12376-448: The removal of natural banks replaced with revetments , this sediment output has been reduced by 60%. The most basic river projects involve the clearing of obstructions like fallen trees. This can scale up to dredging , the excavation of sediment buildup in a channel, to provide a deeper area for navigation. These activities require regular maintenance as the location of the river banks changes over time, floods bring foreign objects into

12495-536: The reverse, death and destruction, especially through floods . This power has caused rivers to have a central role in religion , ritual , and mythology . In Greek mythology , the underworld is bordered by several rivers. Ancient Greeks believed that the souls of those who perished had to be borne across the River Styx on a boat by Charon in exchange for money. Souls that were judged to be good were admitted to Elysium and permitted to drink water from

12614-468: The river, and natural sediment buildup continues. Artificial channels are often constructed to "cut off" winding sections of a river with a shorter path, or to direct the flow of a river in a straighter direction. This effect, known as channelization, has made the distance required to traverse the Missouri River in 116 kilometres (72 mi) shorter. Dikes are channels built perpendicular to

12733-552: The river. Areas of a river with softer rock weather faster than areas with harder rock, causing a difference in elevation between two points of a river. This can cause the formation of a waterfall as the river's flow falls down a vertical drop. A river in a permeable area does not exhibit this behavior and may even have raised banks due to sediment. Rivers also change their landscape through their transportation of sediment , often known as alluvium when applied specifically to rivers. This debris comes from erosion performed by

12852-625: The river. A country that is downstream of another may object to the upstream country diverting too much water for agricultural uses, pollution, as well as the creation of dams that change the river's flow characteristics. For example, Egypt has an agreement with Sudan requiring a specific minimum volume of water to pass into the Nile yearly over the Aswan Dam , to maintain both countries access to water. The importance of rivers throughout human history has given them an association with life and fertility . They have also become associated with

12971-457: The rivers themselves, debris swept into rivers by rainfall, as well as erosion caused by the slow movement of glaciers. The sand in deserts and the sediment that forms bar islands is from rivers. The particle size of the debris is gradually sorted by the river, with heavier particles like rocks sinking to the bottom, and finer particles like sand or silt carried further downriver . This sediment may be deposited in river valleys or carried to

13090-412: The rivers. Due to these impermeable surfaces, these rivers often have very little alluvium carried in them, causing more erosion once the river exits the impermeable area. It has historically been common for sewage to be directed directly to rivers via sewer systems without being treated, along with pollution from industry. This has resulted in a loss of animal and plant life in urban rivers, as well as

13209-409: The sea from their mouths. Depending on the activity of waves, the strength of the river, and the strength of the tidal current, the sediment can accumulate to form new land. When viewed from above, a delta can appear to take the form of several triangular shapes as the river mouth appears to fan out from the original coastline . In hydrology , a stream order is a positive integer used to describe

13328-414: The sea to breed in freshwater rivers are anadromous. Salmon are an anadromous fish that may die in the river after spawning, contributing nutrients back to the river ecosystem. Modern river engineering involves a large-scale collection of independent river engineering structures that have the goal of flood control , improved navigation, recreation, and ecosystem management. Many of these projects have

13447-474: The southern African coast, and its entire eastern portion (see the accompanying map) constitutes the Drakensberg. The Drakensberg terminate in the north near Tzaneen at about the 22° S parallel. The absence of the Great Escarpment for approximately 450 km (280 mi) to the north of Tzaneen (to reappear on the border between Zimbabwe and Mozambique in the Chimanimani Mountains )

13566-519: The spread of waterborne diseases such as cholera . In modern times, sewage treatment and controls on pollution from factories have improved the water quality of urban rivers. Climate change can change the flooding cycles and water supply available to rivers. Floods can be larger and more destructive than expected, causing damage to the surrounding areas. Floods can also wash unhealthy chemicals and sediment into rivers. Droughts can be deeper and longer, causing rivers to run dangerously low. This

13685-410: The surface of the Earth. Rivers flow in channeled watercourses and merge in confluences to form drainage basins , areas where surface water eventually flows to a common outlet. Rivers have a great effect on the landscape around them. They may regularly overflow their banks and flood the surrounding area, spreading nutrients to the surrounding area. Sediment or alluvium carried by rivers shapes

13804-798: The surrounding areas: By 1931, the Kokstad municipal council had assumed a pseudo-heraldic "coat of arms" depicting a landscape with Mount Currie in the background, ears of wheat, and a tree, and the motto Concilio et animis . A proper coat of arms was designed by Ivan Mitford-Barberton in the late 1950s. It was registered with the Cape Provincial Administration in October 1960 and at the Bureau of Heraldry in July 1979. The arms were : Per fess Gules and Or, in chief, dexter

13923-554: The town, the Crystal Spring Dam has become an attraction for both the Kokstad residents, and tourists to the area. There are three rural schemes located in nearby Swartberg, Franklin and Kransdraai, which meet the RDP level of service. Kokstad has many primary and secondary schools, as well as a tertiary institution college. Some of the main schooling institutions are as follows: Kokstad also has two main hospitals that service

14042-547: Was able to secure a 3,000 acres (1,200 ha) farm, but most of them sold their land cheaply to white settlers and squandered their money. The Rev William Dower in his 1902 book The Early Annals of Kokstad describes in great detail how cheaply the Griqua gave their farms away. When, in 1869, the Reverend William Dower was asked by the Griqua to establish a mission, he agreed on condition that they resettle in

14161-494: Was established to preserve some of the high mountain areas of the range. Towns and cities in the Drakensberg area include, from south to north, Matatiele and Barkly East in the Eastern Cape Province; Ladysmith , Newcastle , Ulundi – the former Zulu capital, Dundee , and Ixopo in KwaZulu-Natal; all of Lesotho, whose capital is Maseru ; and Tzaneen in Limpopo Province . There are numerous caves in
