The River Clyde (

Cumbric language, it was known as Clud or Clut. It was central to the Kingdom of Strathclyde
(Teyrnas Ystrad Clut).

Etymology

The exact etymology of the river's name is unclear, though it is known that the name is ancient. In 50AD, the Egyptian mathematician, astronomer and geographer Claudius Ptolemy wrote of the river as "Klōta",[4] It was called Clut or Clud by the Britons and Clota by the Romans. It is therefore likely that the name comes from a Celtic language—most likely Old British. But there is more than one old Celtic word that the river's name could plausibly derive from. One possible root is the Common Brittonic Clywwd, meaning 'loud' or 'loudly'.[citation needed] More likely, the river was named after a local Celtic goddess, Clōta. The goddess's name in turn derives from an older, Proto-Celtic word meaning 'the strongly flowing one' or 'the holy cleanser'.

History

Prehistory

Humans have settled along the Clyde since the Paleolithic era. Artifacts dating from 12,000 BC have been found near Biggar, a rural town close to the river. Biggar is home to an archeological site at which Britain's most ancient artifacts have been unearthed.[5] Prehistoric canoes, used by ancient peoples for transport or trade, have been found in the river.[6] There are a number of Mesolithic sites along the Clyde, especially in the Upper Clyde Valley.[7] Permanent settlements and structures, including what is believed to be a temple to moon gods in Govan, were constructed in the area during the Neolithic and Bronze Ages. Celtic art, language, and other aspects of culture began spreading to the area from the south during this period, and prehistoric artifacts suggest that, by around 1000 BCE, they had become the dominant cultural influences there.

Ancient history

Before the

legions of the Roman Empire arrived in southern Scotland, the river and the area surrounding it had been settled by the Brythonic-speaking Damnonii tribe. It has been suggested that a Damnonii town called Cathures was located there and was the precursor to modern Glasgow.[8] The Damnonii tribe originally distributed power among individual chiefdoms, but at some point before 500 AD the tribe politically unified and formed a centralised kingdom known as Strathclyde
.

None of the documentary or archaeological evidence from the period when the Roman legions arrived suggests that battles took place in the area. Therefore the Roman legions and Damnonii tribespeople are assumed to have been on good terms and to have co-operated by means of trade and the exchange of military information. The Romans did, however, construct several

forts (castra) in the area, notably on the banks of the Clyde. These include Castledykes, Bothwellhaugh, and Old Kilpatrick and Bishopton. The Romans also constructed several roads along the river, both small ones and larger ones designed to be used as trade routes and to carry entire legions. The Antonine Wall, which lies only a few miles from the river, was constructed later by the Romans as a means of defending the area against invasion by the Picts. Despite the strategic location and flat terrain of Glasgow and the surrounding Clyde basin, no Roman civilian settlement was ever constructed. Instead, the region mostly functioned as a frontier zone between the Roman province known as Britannia Inferior and the Caledonians
, an indigenous group that was hostile to the Romans.

Kingdom of Strathclyde

Strathclyde was founded as an independent British kingdom, either during or shortly after the

Welsh culture
: Its territory eventually expanded along the Clyde Vae Southern Uplands and Ayrshire, and southward into Cumbria.

In the

Norse-Irish raiders from the Kingdom of Dublin sacked it. After that, the kingdom, now politically weakened, moved its capital to Govan. However, it never fully recovered, and in the 11th century it was annexed by the Kingdom of Alba

Medieval and early modern history

In the 13th century, Glasgow, then still a small town, built its first bridge over the river Clyde. This was an important step in its ability to eventually grow into a city. The establishment, in the 15th century, of both the University of Glasgow and the Archdiocese of Glasgow, vastly increased the importance of the town within Scotland. From the early modern period onwards, the Clyde began to be used commercially as a trade route; trade between Glasgow and the rest of Europe became commonplace. In the centuries that followed, the Clyde became increasingly vital to both Scotland and Britain as a major trade route for exporting and importing resources.

Course

The Carstairs meanders

The Clyde is formed by the confluence of two streams, the

hydroelectric power station still generates 11MW of electricity there today, although the mills have now become a museum and World Heritage Site
.

Catchment of the River Clyde
Tributaries of the River Clyde

The river then makes its way northwest, past the towns of

Strathclyde Park. Part of the original course can still be seen: It lies between the island and the eastern shore of the loch. The river then flows through Blantyre and Bothwell, where the ruined Bothwell Castle stands on a defensible promontory
.

The river enters the urban environment here, with Glasgow to its north (background) and South Lanarkshire to its south (foreground).
Glasgow Green with Tidal Weir

As it flows past Uddingston and into the southeastern part of Glasgow, the river begins to widen, meandering through Cambuslang, Rutherglen, and Dalmarnock, and past Glasgow Green. From the Tidal Weir westwards, the river is tidal: a mix of fresh and salt water.[10]

Over three centuries the river has been engineered and widened where it passes through Glasgow city centre and onwards towards Dumbarton and Greenock and the open sea. Shipping and shipbuilding grow in Glasgow and its neighbouring industrial burghs of Govan and Partick; with the Clyde, including is lower reaches, becoming the centre of world shipbuilding.

The river then flows west, out of Glasgow, past

Cardross and Helensburgh. Opposite, on the southern shore, is the last remaining Lower Clyde shipyard, at Port Glasgow. The river continues on to Greenock, where it reaches the Tail of the Bank as the river merges into the Firth of Clyde. Here at the mouth of the Clyde, there is currently a significant ecological problem of oxygen depletion in the water column.[11]

The strath of the Clyde was the focus for the G-BASE project executed by the British Geological Survey in the summer of 2010.

Industrial growth

The economic prosperity that the Clyde made possible at the beginning of the Industrial Revolution was due to the location of Glasgow, as a port facing the Americas. Tobacco and cotton trade began to drive this economic engine in the early 18th century. However, an obstacle to further economic growth soon became evident: the Clyde was too shallow for the largest ocean-going ships to navigate into it, so cargo had to be transferred, at Greenock or Port Glasgow, to smaller ships that could sail upstream into Glasgow itself.

Deepening the Upper Clyde

In 1768, John Golborne advised that the river should be made narrower and the scour increased by constructing rubble jetties and dredging sandbanks and shoals. Another obstacle to navigation that had to be solved was that the river divided into two shallow channels by the Dumbuck shoal near Dumbarton. After James Watt's 1769 report describing this problem, a jetty was constructed at Longhaugh Point to block off the southern channel. This turned out to be insufficient to solve the problem, so in 1773, a training wall called the Lang Dyke was built on the Dumbuck shoal to stop water flowing over into the southern channel of the river.

In the late 18th and early 19th centuries, hundreds of jetties were built out from the banks of the river between Dumbuck and the Broomielaw quay in Glasgow proper. In some cases, this construction had the effect of deepening the river, because the increased flow of the newly constrained water wore away the river bottom. In other cases, dredging was required to deepen the river.[12][13][14]

In the mid-19th century, engineers took on the task of dredging the Clyde much more extensively. They removed millions of cubic feet of silt to deepen and widen the channel. The major stumbling block encountered by that project was a massive geological intrusion known as Elderslie Rock.[15] Because that rock increased the project's difficulty, the work was not completed until the 1880s. Around this time, the Clyde became an important source of inspiration for artists, such as John Atkinson Grimshaw and James Kay,[16] who were interested in painting scenes that depicted the new industrial era and the modern world.

Shipbuilding and marine engineering

A Glasgow shipyard in 1944

The completion of the dredging was well-timed, because the channel finally became navigable all the way from Greenock to Glasgow just when the steelwork industry had begun to grow in the city. Shipbuilding replaced trade as the major activity on the river, and shipbuilding companies started rapidly establishing themselves there. The Clyde soon gained a reputation for being the best location for shipbuilding in the British Empire, and grew to become the world's pre-eminent shipbuilding centre. The term Clydebuilt became an industry symbol of high quality, and the river's shipyards were given contracts to build prestigious ocean-going liners, as well as warships. The Queen Mary and, in later years, the Queen Elizabeth 2 were built in the town of Clydebank.

Between 1712, when the

Forth & Clyde Canal, and Blackhill on the Monkland Canal
. Over the same time period, it is estimated that more than 300 firms have engaged in shipbuilding on Clydeside, although probably at most 30 to 40 firms were operating at any given time.

The shipbuilding firms became household names on Clydeside, and even around the world to some extent. These included, among many others,

Alexander Stephen & Sons of Linthouse, Fairfield of Govan, Inglis of Pointhouse, Barclay Curle of Whiteinch, Connell and Yarrow of Scotstoun. Almost as famous were the engineering firms that supplied the machinery needed to drive these vessels, including the boilers, pumps, and steering gear, including Rankin & Blackmore, Hastie's and Kincaid's of Greenock, Rowan's of Finnieston, Weir's of Cathcart, Howden's of Tradeston, and Babcock & Wilcox
of Renfrew.

One shipyard that was known as a 'Clyde' shipyard was not actually located on any of the Clyde's waterways: Alley & MacLellan's Sentinel Works in Jessie Street at Polmadie is around half a mile distant from the Clyde. It is said to have constructed over 500 vessels, many of which were assembled and then 'knocked down' to kit form for despatch to a remote location, such as Chauncy Maples. Clyde shipbuilding reached its peak in the years just before World War I: It is estimated that, in the year 1913 alone, over 370 ships were completed.

Yachting and yachtbuilding

The first recorded Clyde racing yacht, a 46-ton cutter, was built by Scotts of Greenock in 1803.[17] The pre-eminent Scottish yacht designer William Fyfe did not start designing yachts until 1807. The first yacht club on the Clyde was the Northern Yacht Club, which was established in 1824 and received its royal charter in 1831. The club was founded to organise and encourage the sport of yacht racing. By 1825, Scottish and Irish clubs were racing against each other on the Clyde. By the mid-19th century, yachting and yacht building had become widely popular.

The Clyde became famous worldwide for its significant contribution to yachting and yachtbuilding, and was the home of many notable designers: William Fife III, Alfred Mylne, G. L. Watson, E. McGruer, and David Boyd. It was also home to many famous yacht yards.

Robertson's Yard started repairing boats in a small workshop at Sandbank in 1876, and went on to become one of the foremost wooden boat builders on the Clyde. The 'golden years' of Robertson's yard were in the early 20th century, when they started building classic 12-and-15-metre (39 and 49 ft) racing yachts. More than 55 boats were built by Robertson's in preparation for World War I, and the yard remained busy even during the Great Depression in the 1930s, as many wealthy businessmen developed a passion for yacht racing on the Clyde. During World War II, the yard was devoted to Admiralty work, producing large, high-speed Fairmile Marine motor boats (motor torpedo boats and motor gun boats). After the war, the yard built the successful one-class Loch Longs and two 12 m (39 ft) challengers for the America's Cup, designed by David Boyd: Sceptre (1958)[18] and Sovereign (1964). Because of difficult business conditions in 1965, the yard turned to doing GRP production work (mainly building Pipers and Etchells), and it closed in 1980. During its 104-year history, Robertson's Yard built 500 boats, many of which are still sailing today.

Two other notable boatyards on the Clyde were Silvers, which operated from 1910 to 1970, and McGruers, which operated from 1910 to 1973. They were situated on the

Rosneath peninsula on the banks of the Gare Loch, within half a mile of each other. McGruers built over 700 boats. Both yards built many widely-known and classic yachts, some of which are still sailing today.[19][20][21]

Glasgow Humane Society

The Glasgow Humane Society is responsible for the safety and preservation of life on Glasgow's waterways. Founded in 1790, it is the oldest lifesaving organisation in the world.

Shipbuilding decline

Although diminished from its early 20th-century heights, shipbuilding remains an important industry on Clydeside.

During and immediately after

Aircraft and Shipbuilding Industries Act, which nationalised most of the Clyde's shipyards and grouped them with other major British shipyards, such as the firm British Shipbuilders
.

Today, two major shipyards on the Upper Clyde remain in operation. They are both owned by a naval defence contractor,

car ferries
.

Regeneration

Major regeneration schemes include those in the 1970s of forming Strathclyde Country Park, lying between Hamilton and Motherwell, as part of motorway developments; the establishment of the Glasgow Garden Festival 1988 as part of the re-use of city docklands and associated industrial uses led by the Scottish Development Agency in the 1980s and early 90s. The

Scottish Exhibition and Conference Centre, the Glasgow Science Centre, and the Riverside Museum
. Merchant shipping has largely moved west, closer to deeper water at Greenock, and 20 miles beyond that, south, to Hunterston. The river's water is increasingly used for recreation now that industrial uses have diminished.

The

Pollution

The British Geological Survey has identified and evaluated organic chemical pollutants in the sediment of the Clyde estuary.

polyaromatic hydrocarbons (PAH) from 630 µg/kg to 23,711 µg/kg and polychlorinated biphenyl (PCB) in the range of 5 to 130.5 µg/kg, which puts these sediments in the range classified as "non-toxic."[25] However, a later study showed PCB concentrations as high as 5,797 µg/kg, which is above published threshold levels for such chlorinated compounds.[26] A comparison between individual PAH compounds that have different thermal stabilities shows that the source of PAH pollution in the Clyde is different in different parts of the river. PAH in the inner Clyde (Cuningar to Milton) are from combustion sources (vehicle exhaust, coal burning), whereas PAH in the outer Clyde are from petroleum spills.[25][26]

The amount and type of sedimentary pollution in the Clyde reflects the area's industrial history.

Richmond Park, remains heavily contaminated by hexavalent chromium, to the extent it turned bright green in 2019,[28] and yellow in 2021.[29]

Although pollution from heavy industry and power generation has been decreasing, there is evidence that human-made pollution from new synthetic compounds in electrical products and textiles has been increasing.

polybrominated diphenyl ether (PBDE) compounds used as flame retardants in televisions, computers, and furniture upholstery were measured in sediment cores collected from six sites between Princes Dock and Greenock. Comparison of the amounts of PBDE compounds revealed a decline in certain compounds, in line with the European ban on production of mixtures containing environmentally harmful PBDE with eight and nine bromine atoms. At the same time, there was an increase in the amounts of the less harmful mixture, composed of ten bromine atoms.[27]

Media

The Clyde plays an important role in the

W.S. Graham. It also features in the work of many visual artists, including William McTaggart, J. M. W. Turner, Robert Salmon, and George Wyllie
.

The Clyde appears prominently in the films

Black Is the Color (of My True Love's Hair)", as well as "Song of the Clyde", which was popularised by Kenneth McKellar. It is also the subject of longing in Mark Knopfler's "So Far From The Clyde

Heat Pumps

The River Clyde, or more accurately the Clyde Estuary, has significant potential as a heat source. The flow rate downstream alone is around 50 m3/s.[30] Reducing this temperature by 3 °C would enable river heat pumps to extract 188.1 MW of heat. Since river heat pumps typically have an efficiency of 3.0, the heat deliverable is 1.5 times the river component. As a result, the estuary could deliver 282 MW of heat. The temperature of industrial heat pump delivery is typically 80 °C. [citation needed]

In 2020, West Dunbartonshire Council deployed a river source heat pump scheme in the area called Queens Quay. It is the first large heat pump scheme in Britain to deliver at 80 °C. The heat pumps were supplied by Star Refrigeration Ltd, who manufactured them in their Glasgow factory. The project was delivered by Vital Energi.
