80-538: PS Gracie Fields built in 1936, was the last paddle steamer built for Red Funnel as a ferry and excursion steamer. She ran on the Southampton-Cowes route until the outbreak of World War II , when she was requisitioned and served as HMS Gracie Fields as a minesweeper . After successfully evacuating troops from the Dunkirk beaches, she was seriously damaged by an aircraft bomb on 29 May 1940, and sank

160-462: A barge -hauler, Charlotte Dundas , for the Forth and Clyde Canal Company . It successfully hauled two 70-ton barges almost 20 mi (32 km) in 6 hours against a strong headwind on test in 1802. Enthusiasm was high, but some directors of the company were concerned about the banks of the canal being damaged by the wash from a powered vessel, and no more were ordered. While Charlotte Dundas

240-634: A "pollution incident", thus giving the EPA greater investigative powers; earlier testing was described as being primarily intended to ensure public safety. Four varieties of carp were used to stock up fish dams. Since then they have made their way into the river systems, where they spread quite quickly. Human introduction, possibly by anglers using small carp illegally as live bait, has also increased their distribution. These fish are very mobile, breed rapidly and can survive in very shallow water and through long periods of very low dissolved oxygen content. Carp are

320-620: A boat with a pair of paddlewheels at each end turned by men operating compound cranks. The concept was improved by the Italian Roberto Valturio in 1463, who devised a boat with five sets, where the parallel cranks are all joined to a single power source by one connecting rod, an idea adopted by his compatriot Francesco di Giorgio . In 1539, Spanish engineer Blasco de Garay received the support of Charles V to build ships equipped with manually-powered side paddle wheels. From 1539 to 1543, Garay built and launched five ships,

400-644: A double-hulled boat that was propelled on the Firth of Forth by men working a capstan that drove paddles on each side. One of the first functioning steamships , Palmipède , which was also the first paddle steamer, was built in France in 1774 by Marquis Claude de Jouffroy and his colleagues. The 13 m (42 ft 8 in) steamer with rotating paddles sailed on the Doubs River in June and July 1776. In 1783,

480-457: A full rig of sail for when winds were favorable, being unable to complete the voyage under power alone. In 1822, Charles Napier 's Aaron Manby , the world's first iron ship, made the first direct steam crossing from London to Paris and the first seagoing voyage by an iron ship. In 1838, Sirius , a fairly small steam packet built for the Cork to London route, became the first vessel to cross

Murray%E2%80%93Darling basin The Murray–Darling Basin is a large geographical area in the interior of southeastern Australia, encompassing the drainage basin of the tributaries of the Murray River , Australia's longest river , and

640-448: A means of propulsion comes from the fourth– or fifth-century military treatise De Rebus Bellicis (chapter XVII), where the anonymous Roman author describes an ox-driven paddle-wheel warship: Animal power, directed by the resources on ingenuity, drives with ease and swiftness, wherever utility summons it, a warship suitable for naval combats, which, because of its enormous size, human frailty as it were prevented from being operated by

720-559: A new paddle steamer by de Jouffroy, Pyroscaphe , successfully steamed up the river Saône for 15 minutes before the engine failed. Bureaucracy and the French Revolution thwarted further progress by de Jouffroy. The next successful attempt at a paddle-driven steam ship was by Scottish engineer William Symington , who suggested steam power to Patrick Miller of Dalswinton . Experimental boats built in 1788 and 1789 worked successfully on Lochmaben Loch. In 1802, Symington built

800-472: A number still operate. European sidewheelers, such as PS  Waverley , connect the wheels with solid drive shafts that limit maneuverability and give the craft a wide turning radius. Some were built with paddle clutches that disengage one or both paddles so they can turn independently. However, wisdom gained from early experience with sidewheelers deemed that they be operated with clutches out, or as solid-shaft vessels. Crews noticed that as ships approached

880-477: A paddle wheel is normally enclosed in a paddlebox to minimise splashing. The three types of paddle wheel steamer are sidewheeler, with one paddlewheel amidships on each side; sternwheeler, with a single paddlewheel at the stern ; and (rarely) inboard, with the paddlewheel mounted in a recess amidships. The earliest steam vessel s were sidewheelers, and the type was by far the dominant mode of marine steam propulsion, both for steamships and steamboats, until

The ancient Chinese mathematician and astronomer Zu Chongzhi (429–500) had a paddle-wheel ship built on the Xinting River (south of Nanjing ) known as

1040-516: A problem because they feed by sucking gravel from the riverbed and taking all the edible material off it, before returning the rest to the water. This stirs up all the sediment, reducing the quality of the water. A project for developing daughterless carp shows promise for eliminating carp from the river system. Cane toads have entered the upper reaches of the Darling Basin and there are several reports of individuals being found further down

1120-481: A quarter of the Basin lays in the state, the commission was an advisory body with no authority for enforcement of provisions. For a long time the commission was only concerned with water quantity until salinity became a problem. This led to minor reforms in 1982 in which water quality became part of the commission's responsibilities. However, it was soon recognised that a new organisational structure which considered

1200-466: A rod and lever. The geometry is designed such that the paddles are kept almost vertical for the short duration that they are in the water. The use of a paddle wheel in navigation appears for the first time in the mechanical treatise of the Roman engineer Vitruvius ( De architectura , X 9.5–7), where he describes multigeared paddle wheels working as a ship odometer . The first mention of paddle wheels as

1280-502: A side,". The standard Chinese term "wheel ship" was used by the Song period, whereas a litany of colorful terms were used to describe it beforehand. In the 12th century, the Song government used paddle-wheel ships en masse to defeat opposing armies of pirates armed with their own paddle-wheel ships. At the Battle of Caishi in 1161, paddle-wheelers were also used with great success against

1360-419: A simple paddle wheel, where the paddles are fixed around the periphery, power is lost due to churning of the water as the paddles enter and leave the water surface. Ideally, the paddles should remain vertical while under water. This ideal can be approximated by use of levers and linkages connected to a fixed eccentric. The eccentric is fixed slightly forward of the main wheel centre. It is coupled to each paddle by

1440-541: A steam-powered desalinator created by Garay for a steam boiler. In 1705, Papin constructed a ship powered by hand-cranked paddles. An apocryphal story originating in 1851 by Louis Figuire held that this ship was steam-powered rather than hand-powered and that it was therefore the first steam-powered vehicle of any kind. The myth was refuted as early as 1880 by Ernst Gerland  [ de ] , though still it finds credulous expression in some contemporary scholarly work. In 1787, Patrick Miller of Dalswinton invented

1520-563: A volume of water that is large only by Australian standards. The Snowy Mountains Scheme provides some security of water flows to the Murray–Darling Basin, providing approximately 2,100 gigalitres (7.4×10 cu ft) of water a year to the Basin for use in Australia's irrigated agriculture industry, which is worth about A$ 3 billion per annum, representing more than 40% of the gross value of the nation's agricultural production. The Basin

The study found that there were: Historical records show that the previous abundances of fish provided a reliable food source. The bountiful fish became concentrated when the early stages of a flood left shallow water across

1680-467: Is one of the physiographic provinces of the larger East Australian Basins division, and encompasses the smaller Naracoorte Platform and Encounter Shelf physiographic sections. Total water flow in the Murray–Darling Basin 1885 to the present has averaged around 24,000 gigalitres (24,000  hm ; 19,000,000  acre⋅ft ) per year. This is the lowest rate of the world's major river systems. About 6.0 percent of Australia's total rainwater falls into

1760-658: The Crimean War of 1853–1856, and by the United States Navy during the Mexican War of 1846–1848 and the American Civil War of 1861–1865. With the arrival of ironclad battleships from the late 1850s, the last remaining paddle frigates were decommissioned and sold into merchant-navy service by the 1870s. These included Miami , which became one of the first Boston steamers in 1867. At

1840-760: The Darling River , a right tributary of the Murray and Australia's third-longest river. The Basin, which includes six of Australia's seven longest rivers and covers around one-seventh of the Australian landmass, is one of the country's most significant agricultural areas providing one-third of Australia's food supply. Located west of the Great Dividing Range , it drains southwest into the Great Australian Bight and spans most of

1920-486: The Dunkirk Evacuation in 1940, where they were able to get close inshore to embark directly from the beach. One example was PS  Medway Queen , which saved an estimated 7,000 men over the nine days of the evacuation, and claimed to have shot down three German aircraft. Another paddle minesweeper, HMS  Oriole , was deliberately beached twice to allow soldiers to cross to other vessels using her as

2000-664: The Guide to the Proposed Murray–Darling Basin Plan , was released in October 2010 as the first part of a three-stage process to address the problems of the Murray–Darling Basin. The Plan was in response to the 2000s Australian drought , and designed to secure the long-term ecological health of the Murray–Darling Basin. This entailed cutting existing water allocations and tree growth environmental flows . The Basin Plan

2080-860: The Jin dynasty (1115–1234) navy. The Chinese used the paddle-wheel ship even during the First Opium War (1839–1842) and for transport around the Pearl River during the early 20th century. Paddle steamers in Bangladesh were first operated by the River Steam Navigation Company Limited in 1878. Many steamers, including the Garrow , Florikan , Burma , Majabi , Flamingo , Kiyi , Mohamend , Sherpa , Pathan , Sandra , Irani , Seal , Lali , and Mekla , dominated

2160-707: The Racecourse-class minesweepers , were ordered and 32 of them were built before the end of the war. In the Second World War , some thirty pleasure paddle steamers were again requisitioned; an added advantage was that their wooden hulls did not activate the new magnetic mines. The paddle ships formed six minesweeping flotillas , based at ports around the British coast. Other paddle steamers were converted to anti-aircraft ships. More than twenty paddle steamers were used as emergency troop transports during

2240-609: The Ramsar Convention of Wetlands of International Importance. The rivers listed below comprise the Murray–Darling Basin and its direct significant tributaries, with elevations of their confluence with the downstream river. The tributary with the highest elevation is Swampy Plain River that rises in the Snowy Mountains, below Mount Kosciuszko at an elevation of 2,120 metres (6,960 ft), and ends merging with

2320-680: The River Clyde in 1812. In 1812, the first U.S. Mississippi River paddle steamer began operating out of New Orleans. By 1814, Captain Henry Shreve had developed a "steamboat" suitable for local conditions. Landings in New Orleans went from 21 in 1814 to 191 in 1819, and over 1,200 in 1833. The first stern-wheeler was designed by Gerhard Moritz Roentgen from Rotterdam, and used between Antwerp and Ghent in 1827. Team boats , paddle boats driven by horses, were used for ferries

2400-581: The Thames steamers which took passengers from London to Southend-on-Sea and Margate , Clyde steamers that connected Glasgow with the resort of Rothsay and the Köln-Düsseldorfer cruise steamers on the River Rhine . Paddle steamer services continued into the mid-20th century, when ownership of motor cars finally made them obsolete except for a few heritage examples. The first mention of

2480-506: The " thousand league boat ". When campaigning against Hou Jing in 552, the Liang dynasty (502–557) admiral Xu Shipu employed paddle-wheel boats called "water-wheel boats". At the siege of Liyang in 573, the admiral Huang Faqiu employed foot-treadle powered paddle-wheel boats. A successful paddle-wheel warship design was made in China by Prince Li Gao in 784 AD, during an imperial examination of

2560-423: The 1820s, paddle steamers were used to take tourists from the rapidly expanding industrial cities on river cruises, or to the newly established seaside resorts , where pleasure piers were built to allow passengers to disembark regardless of the state of the tide. Later, these paddle steamers were fitted with luxurious saloons in an effort to compete with the facilities available on the railways. Notable examples are

2640-537: The 1890s. Currently, 4 major reservoirs, 14 lock and weir structures, and five coastal barrages interject the water flowing down the Murray–Darling. Of the approximately 13,000 gigalitres (13,000 hm ; 10,500,000 acre⋅ft) of flow in the Basin, which studies have shown to be divertible, 11,500 gigalitres (11,500 hm ; 9,320,000 acre⋅ft) are removed for irrigation, industrial use, and domestic supply. Agricultural irrigation accounts for about 95 percent of

2720-619: The 1980s, the steam engines were replaced with diesel ones, and the wooden paddles were replaced with iron ones. Hydraulic steering was introduced in the 1990s, followed by electro-hydraulic systems in 2020. Modern equipment such as radar and GPS was also installed. However, PS Gazi , PS Teal , and PS Kiwi were decommissioned in the late '90s after catching fire while docked for repairs. Until 2022, four paddle steamers—PS Ostrich (built in Scotland in 1929), PS Mahsud (1928), PS Lepcha (1938), and PS Tern (1950)—were operated by

2800-467: The Atlantic under sustained steam power, beating Isambard Kingdom Brunel 's much larger Great Western by a day. Great Western , however, was actually built for the transatlantic trade, and so had sufficient coal for the passage; Sirius had to burn furniture and other items after running out of coal. Great Western ' s more successful crossing began the regular sailing of powered vessels across

2880-644: The Atlantic. Beaver was the first coastal steamship to operate in the Pacific Northwest of North America. Paddle steamers helped open Japan to the Western World in the mid-19th century. The largest paddle-steamer ever built was Brunel's Great Eastern , but it also had screw propulsion and sail rigging. It was 692 ft (211 m) long and weighed 32,000 tons, its paddlewheels being 56 ft (17 m) in diameter. In oceangoing service, paddle steamers became much less useful after

2960-697: The BIWTC once a week. This was a reduction from daily trips, and commercial services were eventually stopped altogether due to safety concerns, operational losses, and a lack of passengers, especially following the inauguration of the Padma Bridge . The first seagoing trip of a paddle steamer was by the Albany in 1808. It steamed from the Hudson River along the coast to the Delaware River . This

Nevertheless, these waters are subject to major diversions for municipal drinking supplies and irrigated agriculture that began in

3120-463: The Basin. In most years only half of this quantity reaches the sea and in dry years much less. Estimated total annual flows for the Basin have ranged from 5,000 gigalitres (5,000 hm ; 4,100,000 acre⋅ft) in 1902 to 57,000 gigalitres (57,000 hm ; 46,000,000 acre⋅ft) in 1956. Despite the magnitude of the Basin, the hydrology of the streams within it is quite varied. These waters are divided into four types: The two principal rivers of

3360-510: The Mississippi . Recessed or inboard paddlewheel boats were designed to ply narrow and snag-infested backwaters. By recessing the wheel within the hull it was protected somewhat from damage. It was enclosed and could be spun at a high speed to provide acute maneuverability. Most were built with inclined steam cylinders mounted on both sides of the paddleshaft and timed 90 degrees apart like a locomotive, making them instantly reversing. In

The ordering of the Basin, from downstream to upstream, is: The Basin affects five states and territory governments, which according to the Constitution , are responsible for managing water resources. The River Murray Commission was established in 1917. Under the River Murray Waters Agreement , which did not include Queensland though about

However, during "the Big Dry", as the early 2000s drought came to be known, Australian farmers experienced a scarcity unlike ever before. The drought was so severe that numerous rivers and streams such as the Murray–Darling stopped flowing. The Basin contains more than 30,000 wetlands . Eleven of these are protected under

3600-543: The Seine, between Paris and Le Havre. The first paddle-steamer to make a long ocean voyage crossing the Atlantic Ocean was SS  Savannah , built in 1819 expressly for this service. Savannah set out for Liverpool on May 22, 1819, sighting Ireland after 23 days at sea. This was the first powered crossing of the Atlantic, although Savannah was built as a sailing ship with a steam auxiliary; she also carried

After the American Civil War, as the expanding railroads took many passengers, the traffic became primarily bulk cargoes. The largest, and one of the last, paddle steamers on the Mississippi was the sternwheeler Sprague . Built in 1901, she pushed coal and petroleum until 1948. In Europe from

Conversely, support for the Murray–Darling Basin plan has been received by various groups, including Australian Conservation Foundation , and Environment Victoria . New legal advice from Commonwealth government lawyers is changing the plan. The Government's interpretation is that the plan must give equal weight to the environmental, social, and economic impacts of proposed cuts to irrigation. Environmentalists and South Australian irrigators, at

One of the first screw-driven warships, HMS  Rattler  (1843) , demonstrated her superiority over paddle steamers during numerous trials, including one in 1845 where she pulled a paddle-driven sister ship backwards in a tug of war . However, paddle warships were used extensively by the Russian Navy during

In October 2010, a parliamentary inquiry into the economic impacts of the plan was announced. In late October 2010 the Water Minister, Tony Burke, played down the prospect of a High Court challenge to the Murray–Darling Basin plan, as confusion continued over new legal advice released by the Government. In response to community concerns that MDBA had put environmental issues first over social and economic needs, Burke released new advice on

At the beginning of the Second World War she was requisitioned by the Admiralty and served as a minesweeper . On 29 May 1940, the ship took part in the Dunkirk evacuation, rescuing 280 troops on the first trip. However, on the second trip, with 750 men on board, she was attacked by German aircraft resulting in

This warship, moreover, because of its own bulk and because of

4560-467: The increasing adoption of screw propulsion from the 1850s. Though the side wheels and enclosing sponsons make them wider than sternwheelers, they may be more maneuverable, since they can sometimes move the paddles at different speeds, and even in opposite directions. This extra maneuverability makes side-wheelers popular on the narrower, winding rivers of the Murray–Darling system in Australia, where

With the release of the Guide to the Proposed Murray–Darling Basin Plan there have been a number of protests and voiced concerns about the plan in rural towns that the MDBA visited to present the plan to consultation meetings. More than 5,000 people attended a MDBA meeting in Griffith where Griffith Mayor, Mike Neville, said the plan would "obliterate" Murrumbidgee valley communities. Other groups also echo this feeling, such as

Phyla canescens has invaded wetlands and floodplains with heavy clay soils in the Murray–Darling Basin, to the detriment of the native vegetation; the plant does best in habitats that are inundated occasionally, although it cannot compete with the grass Paspalum distichum and the sedge Eleocharis plana in more heavily inundated sites. This area

5760-423: The water removed, including for the growing of rice and cotton . This extraction is highly controversial among scientists in Australia, regarding the agriculture industry's high water use in a region extremely short of water (as much due to exceptionally low run-off coefficients as to low rainfall). These extensive irrigation systems require a reliable supply of water, not the unpredictable flows that characterise

5840-426: The wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An engine rotates the paddle wheel in the water to produce thrust , forward or backward as required. More advanced paddle-wheel designs feature "feathering" methods that keep each paddle blade closer to vertical while in the water to increase efficiency. The upper part of

5920-444: Was designed to set environmentally sustainable limits on the quantities of water that may be taken from Basin water resources , to set Basin-wide environmental, water quality and salinity objectives, to develop efficient water trading regimes across the Basin, to set requirements for state water resource plans and to improve water security for all Basin users. It also intends to minimise social and economic impacts whilst achieving

6000-626: Was formed in 2008 to manage the Murray–Darling Basin in an integrated and sustainable manner. The MDBA is responsible for preparing and overseeing a legally-enforceable management plan. In October 2010, MDBA released a draft Murray–Darling Basin Plan (MDBP) for consultation. On 22nd November 2012, Tony Burke signed the Murray–Darling Basin Plan, which passed the Australian Parliament's disallowance period on 19 March 2013. The MDBA's draft Murray–Darling Basin Plan, titled

6080-635: Was once home to a large number of Aboriginal people whose traditional lifestyle and cultures were gradually altered by the arrival of Europeans, while others were outright killed by the settlers. Although some tribes organised resistance, such as the Maraura , whose territory lay around the Rufus River above Renmark and the Tanganekald near The Coorong , they were eventually either killed, exiled, or succumbed to disease. The Murray–Darling Basin

6160-446: Was propelled by a diagonal compound steam engine of 137 nhp , also made by Thornycroft and giving a service speed of 14 knots (26 km/h; 16 mph). To increase manoeuvrability when going astern, she was fitted with a bow rudder. Accommodation for cars was provided on the fore deck. She was launched by her namesake, the singer Gracie Fields , on 8 April 1936. After a cruise for invited guests on 9 May, she entered revenue service

6240-469: Was purely for the purpose of moving a river-boat to a new market, but paddle-steamers began regular short coastal trips soon after. In 1816 Pierre Andriel, a French businessman, bought in London the 15  hp (11 kW) paddle steamer Margery (later renamed Elise ) and made an eventful London- Le Havre -Paris crossing, encountering heavy weather on the way. He later operated his ship as a river packet on

6320-650: Was steamed from Newcastle to San Francisco. As the voyage was intended to be completed under power, the tug was rigged as steam propelled with a sail auxiliary. The transatlantic stage of the voyage was completed exactly 150 years after the voyage of Savannah . As of 2022, the PS Waverley is the last seagoing passenger-carrying paddle steamer in the world. Beginning in the 1820s, the British Royal Navy began building paddle-driven steam frigates and steam sloops . By 1850 these had become obsolete due to

6400-463: Was the first commercial paddle steamer and steamboat , the first commercial success was possibly Robert Fulton 's Clermont in New York, which went into commercial service in 1807 between New York City and Albany . Many other paddle-equipped river boats followed all around the world; the first in Europe being PS  Comet designed by Henry Bell which started a scheduled passenger service on
