75-708: The Ganges Canal or Ganga Canal is a canal system that irrigates the Doab region between the Ganges River and the Yamuna River in India. The canal is primarily an irrigation canal, although parts of it were also used for navigation, primarily for its construction materials. Separate navigation channels with lock gates were provided on this system for boats to negotiate falls. Originally constructed from 1842 to 1854, for an original head discharge of 6000 ft³/s,

150-547: A caisson of water in which boats float while being moved between two levels; and inclined planes where a caisson is hauled up a steep railway. To cross a stream, road or valley (where the delay caused by a flight of locks at either side would be unacceptable) the valley can be spanned by a navigable aqueduct – a famous example in Wales is the Pontcysyllte Aqueduct (now a UNESCO World Heritage Site ) across

225-510: A drainage divide atop a ridge , generally requiring an external water source above the highest elevation . The best-known example of such a canal is the Panama Canal . Many canals have been built at elevations, above valleys and other waterways. Canals with sources of water at a higher level can deliver water to a destination such as a city where water is needed. The Roman Empire 's aqueducts were such water supply canals. The term

300-415: A "cistern", or depressed area just downstream from the fall, to "cushion" the water by providing a deep pool for its kinetic energy to be diffused in. Vertical falls work for drops of up to 1.5 m in height, and for discharge of up to 15 cubic meters per second. The transport capacity of pack animals and carts is limited. A mule can carry an eighth-ton [250 pounds (113 kg)] maximum load over

375-496: A canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as slack water levels , often just called levels . A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin , and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley . A canal can cut across

450-642: A central element in the creations accounts of almost every culture with mythological, cosmological , and theological myths. In this way, many groups characterize water as "living water", or the "water of life". This means that it gives life and is the fundamental element from which life arises. Each religious or cultural group that feature waters as sacred substances tends to favor certain categorizations of some waters more than others, usually those that are most accessible to them and that best integrate into their rituals. While all rivers in Hinduism are sacred,

525-413: A combination of the three, depending on available water and available path: Smaller transportation canals can carry barges or narrowboats , while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal ), or from one sea or ocean to another (e.g., Caledonian Canal , Panama Canal ). At their simplest, canals consist of a trench filled with water. Depending on

600-496: A deceased person is cleansed by the Ganges, it will help liberate their soul , or expedite the number of lives they need to achieve this. In the traditional funerary ceremony, a dead person is placed upon a funeral pyre until the body becomes cremated , then the ashes are sent upon the river. Many Hindus go to great lengths to purify themselves one last time before death. When this is not possible, family members will actually mail

675-488: A direct connection to the watery underworld and underground water obtained through a cave as an even better connection to spirits and deities. Cenotes are very important to the Mayas. The famous Sacred Cenote at Chichen Itza proves to be important with the many findings of artifacts and skeletal remains. Sacrifices were common at this site among the ancient Maya. Different people were sacrificed and findings show that most of

750-549: A journey measured in days and weeks, though much more for shorter distances and periods with appropriate rest. Besides, carts need roads. Transport over water is much more efficient and cost-effective for large cargoes. The oldest known canals were irrigation canals, built in Mesopotamia c.  4000 BC , in what is now Iraq . The Indus Valley civilization of ancient India ( c.  3000 BC ) had sophisticated irrigation and storage systems developed, including

825-581: A rather low gradient for its time. The canal is still in use after renovation. In the Middle Ages , water transport was several times cheaper and faster than transport overland. Overland transport by animal drawn conveyances was used around settled areas, but unimproved roads required pack animal trains, usually of mules to carry any degree of mass, and while a mule could carry an eighth ton, it also needed teamsters to tend it and one man could only tend perhaps five mules, meaning overland bulk transport

900-455: A result, at Roorkee the canal is 25 metres higher than the original river. When the canal formally opened on 8 April 1854, its main channel was 348 miles (560 km) long, its branches 306 miles (492 km) long and the various tributaries over 3,000 miles (4,800 km) long. After irrigation was commenced in May 1855, over 767,000 acres (3,100 km) in 5,000 villages were irrigated. In 1877

975-459: A uniform altitude. Other, generally later, canals took more direct routes requiring the use of various methods to deal with the change in level. Canals have various features to tackle the problem of water supply. In cases, like the Suez Canal, the canal is open to the sea. Where the canal is not at sea level, a number of approaches have been adopted. Taking water from existing rivers or springs

1050-528: A very illustrative account of his personal visit to the Ganges in which he described seeing both animal and human corpses floating down the river or sometimes embedded in heaps of garbage. People continued to bathe, and children to play in very murky waters; the color in some parts completely changed from toxic sewage and runoff . As the Ganges River remains interwoven into daily existence, Hindus are vulnerable to urban contamination. Lake Titicaca

1125-422: Is a channel that cuts across a drainage divide , making a navigable channel connecting two different drainage basins . Both navigations and canals use engineered structures to improve navigation: Since they cut across drainage divides, canals are more difficult to construct and often need additional improvements, like viaducts and aqueducts to bridge waters over streams and roads, and ways to keep water in

1200-701: Is presumed, introduced in Italy by Bertola da Novate in the 16th century. This allowed wider gates and also removed the height restriction of guillotine locks . To break out of the limitations caused by river valleys, the first summit level canals were developed with the Grand Canal of China in 581–617 AD whilst in Europe the first, also using single locks, was the Stecknitz Canal in Germany in 1398. In

1275-599: Is rarely less than 30 metres (98 ft) wide. In the 5th century BC, Achaemenid king Xerxes I of Persia ordered the construction of the Xerxes Canal through the base of Mount Athos peninsula, Chalkidiki , northern Greece. It was constructed as part of his preparations for the Second Persian invasion of Greece , a part of the Greco-Persian Wars . It is one of the few monuments left by

1350-494: Is said to purify the soul of negative karma , corporeal sins , and even impurities from previous lives . At sunrise along the Ganges, pilgrims descend the ghat steps to drink of the waters, bathe themselves in the waters and perform ablutions where they submerge their entire bodies. These practitioners desire to imbibe and surround themselves with the Ganges’s waters so that they can be purified. Hindu conceptualizations of

1425-418: Is steeper than the desired canal gradient. They are constructed so the falling water's kinetic energy is dissipated in order to prevent it from scouring the bed and sides of the canal. A canal fall is constructed by cut and fill . It may be combined with a regulator, bridge, or other structure to save costs. There are various types of canal falls, based on their shape. One type is the ogee fall, where

1500-452: Is the pound lock , which consists of a chamber within which the water level can be raised or lowered connecting either two pieces of canal at a different level or the canal with a river or the sea. When there is a hill to be climbed, flights of many locks in short succession may be used. Prior to the development of the pound lock in 984 AD in China by Chhaio Wei-Yo and later in Europe in

1575-572: Is widely known as being a sacred place for the Inca people. The Inca Empire origins lie in Lake Titicaca. Ancient Incan myths describe the Incas as being blessed by the sun because the sun first emerged from Lake Titicaca. Since then, the sun organizes social order and the movement of the sun organizes rituals and gatherings. The first emergence of people in the time of the sun emergence is said to be

1650-658: The Elbe , Oder and Weser being linked by canals. In post-Roman Britain, the first early modern period canal built appears to have been the Exeter Canal , which was surveyed in 1563, and open in 1566. The oldest canal in the European settlements of North America, technically a mill race built for industrial purposes, is Mother Brook between the Boston, Massachusetts neighbourhoods of Dedham and Hyde Park connecting

1725-565: The Ganges River (Ganga) is particularly revered. In the Vedic myths , the goddess Ganga descended upon the earth to purify and prepare the dead. The Ganges in India is seen as the physical embodiment of this goddess. Since the river waters are as both inherently pure themselves and having major purificatory qualities, people come to bathe in them, drink from them, leave offerings for them, and give their physical remains to them. The Ganges

1800-777: The Kanpur branch and Etawah branch. A channel from Chaudhary Charan Singh Ganga barrage at Narora (Bulandshahr district) intersects the canal system 48 km downstream from Nanau (Aligarh district), and continues past the Sengar River and Sersa River , past Shikohabad in Firozabad District to become the Bhognipur branch which was opened in 1880. This branch, starting at village Jera in Mainpuri district, runs for 166 km to reach Kanpur. At kilometre 64

1875-543: The Naviglio Grande built between 1127 and 1257 to connect Milan with the river Ticino . The Naviglio Grande is the most important of the lombard " navigli " and the oldest functioning canal in Europe. Later, canals were built in the Netherlands and Flanders to drain the polders and assist transportation of goods and people. Canal building was revived in this age because of commercial expansion from

1950-545: The Phoenix metropolitan area was the most complex in ancient North America. A portion of the ancient canals has been renovated for the Salt River Project and now helps to supply the city's water. The Sinhalese constructed the 87 km (54 mi) Yodha Ela in 459 A.D. as a part of their extensive irrigation network which functioned in a way of a moving reservoir due to its single banking aspect to manage

2025-528: The River Brue at Northover with Glastonbury Abbey , a distance of about 1.75 kilometres (1,900 yd). Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. More lasting and of more economic impact were canals like

2100-614: The Songhai Empire of West Africa, several canals were constructed under Sunni Ali and Askia Muhammad I between Kabara and Timbuktu in the 15th century. These were used primarily for irrigation and transport. Sunni Ali also attempted to construct a canal from the Niger River to Walata to facilitate conquest of the city but his progress was halted when he went to war with the Mossi Kingdoms . Around 1500–1800

2175-583: The Vimose comb . These depositions are typically interpreted as gifts to gods , aiming to either give thanks for, or receive, positive outcomes such as good harvests, success in water or safe passage across the body of water. Bog bodies found in Germanic areas, such as the Grauballe Man , have often been interpreted as sacrifices, however alternative, but not mutually exclusive, proposals include that

2250-458: The elite in their caste system. The origin of the elite was and continues to be contested among the people on the Island of Lake Titicaca. Thus, creating competition to become part of the elite rank. In recent times, the pollution of Lake Titicaca has built up and caused an increase of green algae . The people of Lake Titicaca Special Projects continuously are creating ways to bring awareness to

2325-556: The reservoirs built at Girnar in 3000 BC. This is the first time that such planned civil project had taken place in the ancient world. In Egypt , canals date back at least to the time of Pepi I Meryre (reigned 2332–2283 BC), who ordered a canal built to bypass the cataract on the Nile near Aswan . In ancient China , large canals for river transport were established as far back as the Spring and Autumn period (8th–5th centuries BC),

2400-404: The stratum the canal passes through, it may be necessary to line the cut with some form of watertight material such as clay or concrete. When this is done with clay, it is known as puddling . Canals need to be level, and while small irregularities in the lie of the land can be dealt with through cuttings and embankments, for larger deviations other approaches have been adopted. The most common

2475-471: The 12th century. River navigations were improved progressively by the use of single, or flash locks . Taking boats through these used large amounts of water leading to conflicts with watermill owners and to correct this, the pound or chamber lock first appeared, in the 10th century in China and in Europe in 1373 in Vreeswijk , Netherlands. Another important development was the mitre gate , which was, it

2550-472: The 15th century, either flash locks consisting of a single gate were used or ramps, sometimes equipped with rollers, were used to change the level. Flash locks were only practical where there was plenty of water available. Locks use a lot of water, so builders have adopted other approaches for situations where little water is available. These include boat lifts , such as the Falkirk Wheel , which use

2625-686: The Balrai escape carries excess water through a 6.4 km. channel through the ravines to discharge into the Yamuna. This branch has 386 km. of distributary channels. The Bhognipur branch, together with the Kanpur and Etawah branches, is known as the Lower Ganges Canal. The old channels of the old Kanpur and Etawah branches between Nanau and the point of intersection by the channel from Narora, are known as "stumps", and are utilized only when

2700-577: The Black Mesa to transport their mining minerals. In May 2002 the Navajo and Hopi people from northeastern Arizona joined their people in St. Louis Missouri to fight against Peabody Energy and its shareholders. In January 2002 Peabody proposed and was granted the right to use thirty-two percent more Navajo Aquifer (Naquifer) water than they had already been using. The significant increase in water pumped out of

2775-603: The British East India Company to sponsor the project. Digging of the canal began in April 1842. Cautley had to make his own bricks, brick kiln and mortar. Initially, he was opposed by the Hindu priests at Haridwar, who felt that the waters of the holy river Ganges would be imprisoned but Cautley pacified them by agreeing to leave a gap in the dam from where the water could flow unchecked. He further appeased

2850-551: The Lower Ganges Canal which constitutes several branches below Aligarh. The Upper Ganges canal is the important and the original Ganges Canal , which starts at the Bhimgoda Barrage near Har ki Pauri at Haridwar , traverses Roorkee , Purquazi , Sardhana (Meerut district), Muradnagar , Dasna , Bulandshahr , Khurja , Harduaganj and continues to Nanau (near Akrabad) in Aligarh district , where it bifurcates into

2925-461: The Naquifer, dramatically affected the drinkability of the water from the springs and wells connected to the Naquifer. Before the significant increase of pumping, the water was clean enough to drink without any kind of purification. Another result of the pumping is the noticeable drop in the water levels of the springs and wells. The drop in water levels was almost immediately recognized after Peabody

3000-421: The Navajo and Hopi people. In respect for the water, these people carryout religious and ceremonial tributes to the water of the Black Mesa. These waters have organized their people around the Black Mesa and resulted in the reliance of the waters for all aspects of their lives. With the emergence of Peabody Energy came threats to the preservation of their sacred water. Peabody Energy pumps water out from underneath

3075-590: The Persian Empire in Europe . Greek engineers were also among the first to use canal locks , by which they regulated the water flow in the Ancient Suez Canal as early as the 3rd century BC. There was little experience moving bulk loads by carts, while a pack-horse would [i.e. 'could'] carry only an eighth of a ton. On a soft road a horse might be able to draw 5/8ths of a ton. But if

3150-785: The Southwest by 1300 CE. Archaeologists working at a major archaeological dig in the 1990s in the Tucson Basin, along the Santa Cruz River, identified a culture and people that may have been the ancestors of the Hohokam. This prehistoric group occupied southern Arizona as early as 2000 BCE, and in the Early Agricultural period grew corn, lived year-round in sedentary villages, and developed sophisticated irrigation canals. The large-scale Hohokam irrigation network in

3225-505: The Upper Ganges Canal has since been enlarged gradually for the present head discharge of 10,500 ft³/s (295 m³/s). The system consists of main canal of 272 miles and about 4,000 miles long distribution channels. The canal system irrigates nearly 9,000 km² of fertile agricultural land in ten districts of Uttar Pradesh and Uttarakhand . Today the canal is the source of agricultural prosperity in much of these states, and

3300-418: The ashes to a priest so that he can perform the ceremony of entering the waters. Manu , the mythic law giver, gave directives and prohibitions regarding the river: “impure objects like urine, feces, spit; or anything which has these elements, blood, or poison should not be cast into the water”. Few or none of his directives hold forth along most places down the Ganges today. Journalist Joshua Hammer wrote

3375-436: The canal pressure with the influx of water. It was also designed as an elongated reservoir passing through traps creating 66 mini catchments as it flows from Kala Wewa to Thissa Wawa . The canal was not designed for the quick conveying of water from Kala Wewa to Thissa Wawa but to create a mass of water between the two reservoirs, which would in turn provided for agriculture and the use of humans and animals. They also achieved

3450-418: The canal to form a dam. They are generally placed in pre-existing grooves in the canal bank. On more modern canals, "guard locks" or gates were sometimes placed to allow a section of the canal to be quickly closed off, either for maintenance, or to prevent a major loss of water due to a canal breach. A canal fall , or canal drop, is a vertical drop in the canal bed. These are built when the natural ground slope

3525-462: The canal. Where large amounts of goods are loaded or unloaded such as at the end of a canal, a canal basin may be built. This would normally be a section of water wider than the general canal. In some cases, the canal basins contain wharfs and cranes to assist with movement of goods. When a section of the canal needs to be sealed off so it can be drained for maintenance stop planks are frequently used. These consist of planks of wood placed across

3600-469: The channel. There are two broad types of canal: Historically, canals were of immense importance to commerce and the development, growth and vitality of a civilization. In 1855 the Lehigh Canal carried over 1.2 million tons of anthracite coal; by the 1930s the company which built and operated it for over a century ceased operation. The few canals still in operation in our modern age are a fraction of

3675-399: The drop follows an s-shaped curve to create a smooth transition and reduce turbulence . However, this smooth transition does not dissipate the water's kinetic energy, which leads to heavy scouring. As a result, the canal needs to be reinforced with concrete or masonry to protect it from eroding. Another type of canal fall is the vertical fall, which is "simple and economical". These feature

They carry free, calm surface flow under atmospheric pressure , and can be thought of as artificial rivers . In most cases,

3825-670: The first summit level canal to use pound locks in Europe was the Briare Canal connecting the Loire and Seine (1642), followed by the more ambitious Canal du Midi (1683) connecting the Atlantic to the Mediterranean. This included a staircase of 8 locks at Béziers , a 157 metres (515 ft) tunnel, and three major aqueducts. Canal building progressed steadily in Germany in the 17th and 18th centuries with three great rivers,

3900-462: The freedom to make deliveries well away from rail lined road beds or ditches in the dirt which could not operate in the winter. The longest extant canal today, the Grand Canal in northern China, still remains in heavy use, especially the portion south of the Yellow River . It stretches from Beijing to Hangzhou at 1,794 kilometres (1,115 miles). Canals are built in one of three ways, or

3975-735: The higher waters of the Charles River and the mouth of the Neponset River and the sea. It was constructed in 1639 to provide water power for mills. In Russia, the Volga–Baltic Waterway , a nationwide canal system connecting the Baltic Sea and Caspian Sea via the Neva and Volga rivers, was opened in 1718. Holy river Ubiquitous and perpetual fixations with water occur across religious traditions. It tends to be

The ancient Maya strived and focused their actions on pleasing their many gods. Essentially, the Maya believed that the world consisted of three layers: the watery underworld , the middle earthly realm, and the sky realm. The Maya viewed bodies of water as

4125-429: The irrigation departments of these states actively maintain the canal against a fee system charged from users. There are some small hydroelectric plants on the canal capable of generating about 33 MW if running at full capacity these are at Nirgajini, Chitaura, Salawa, Bhola, Jani, Jauli and Dasna. The canal is administratively divided into the Upper Ganges Canal from Haridwar to Aligarh , with some branches, and

4200-549: The load were carried by a barge on a waterway, then up to 30 tons could be drawn by the same horse. — technology historian Ronald W. Clark referring to transport realities before the industrial revolution and the Canal age . Hohokam was a society in the North American Southwest in what is now part of Arizona , United States, and Sonora , Mexico. Their irrigation systems supported the largest population in

4275-480: The longest canal in the world today and the oldest extant one. It is 1,794 kilometres (1,115 mi) long and was built to carry the Emperor Yang Guang between Zhuodu ( Beijing ) and Yuhang ( Hangzhou ). The project began in 605 and was completed in 609, although much of the work combined older canals, the oldest section of the canal existing since at least 486 BC. Even in its narrowest urban sections it

4350-534: The longest one of that period being the Hong Gou (Canal of the Wild Geese), which according to the ancient historian Sima Qian connected the old states of Song, Zhang, Chen, Cai, Cao, and Wei. The Caoyun System of canals was essential for imperial taxation, which was largely assessed in kind and involved enormous shipments of rice and other grains. By far the longest canal was the Grand Canal of China , still

4425-506: The numbers that once fueled and enabled economic growth, indeed were practically a prerequisite to further urbanization and industrialization. For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising

4500-530: The people were men and children. Like any archeological site, looting is a problem in preserving and studying the cenote at Chichen Itza. The Navajo and Hopi people have long embraced the water underneath and around the Black Mesa area as sacred to their people. The people have long lived around and became dependent on springs and wells of the Black Mesa. These waters are the only source of drinking water, water for livestock, and water for agriculture for

It is also important to note that human depositions are notably rare in comparison to other finds. Many lakes and rivers have names that are linked to beings such as gods, including Tyesmere ( Tīw 's mere) in England and Tissø ( Týr 's or god 's lake) in Denmark . The latter body of water

The dam was faced with many complications- among them was the problem of the mountainous streams that threatened the canal. Near Roorkee , the land fell away sharply and Cautley had to build an aqueduct to carry the canal for half a kilometre. As

4800-410: The sacred are fluid and renewable. Purity and pollution exist upon a continuum where most entities, including people, can become sacred and then become stagnated and full of sin once again. Performing these rituals is also an act to become closer to the Hindu deities , and ultimately the Divine . The Ganges is one of the most highly favored sites for funerary rituals in India. It is presumed that if

4875-480: The standard of living for any industrialized society. Most ship canals today primarily service bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement

4950-409: The supply of water in the lower Ganges system runs low. The main branch of the river passes Kanpur (behind IIT Kanpur campus) before breaking into several branches. A branch of it terminates Kanpur Jal Sansthan which comes from behind J. K. Temple . An irrigation system was felt necessary after the disastrous Agra famine of 1837–38 , in which nearly 800,000 people died, and nearly ten million rupees

5025-399: The valley of the River Dee . Another option for dealing with hills is to tunnel through them. An example of this approach is the Harecastle Tunnel on the Trent and Mersey Canal . Tunnels are only practical for smaller canals. Some canals attempted to keep changes in level down to a minimum. These canals known as contour canals would take longer, winding routes, along which the land was

5100-426: The whole canal system of the lower Doabs underwent radical alteration. The Lower Ganges Canal, with a feed from a channel from Narora, was constructed into the ghar tract of Etawah, and became the Bhognipur branch. Around 1900, according to the Nuttall Encyclopedia of 1907, it had a total extent of 3,700 miles (6,000 km), of which 500 miles (800 km) were navigable. Building of this canal also eventually led to

5175-466: Was also expensive, as men expect compensation in the form of wages, room and board. This was because long-haul roads were unpaved, more often than not too narrow for carts, much less wagons, and in poor condition, wending their way through forests, marshy or muddy quagmires as often as unimproved but dry footing. In that era, as today, greater cargoes, especially bulk goods and raw materials , could be transported by ship far more economically than by land; in

5250-458: Was an option in some cases, sometimes supplemented by other methods to deal with seasonal variations in flow. Where such sources were unavailable, reservoirs  – either separate from the canal or built into its course – and back pumping were used to provide the required water. In other cases, water pumped from mines was used to feed the canal. In certain cases, extensive "feeder canals" were built to bring water from sources located far from

5325-407: Was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster , less geographically constrained & limited, and generally cheaper to maintain railways . By the early 1880s, canals which had little ability to economically compete with rail transport, were off the map. In the next couple of decades, coal

5400-641: Was granted permission to pump out more water. This had caused disruption in the ceremonial and cultural lives of the Navajo and Hopi people as well as disruption to their farming. Watery places have been considered holy in Germanic cultures since the Nordic Bronze Age and used for diverse religious purposes, such as depositions of items such as the Dejbjerg wagon , the Gundestrup cauldron and

5475-424: Was increasingly diminished as the heating fuel of choice by oil, and growth of coal shipments leveled off. Later, after World War I when motor-trucks came into their own, the last small U.S. barge canals saw a steady decline in cargo ton-miles alongside many railways, the flexibility and steep slope climbing capability of lorries taking over cargo hauling increasingly as road networks were improved, and which also had

A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal

One of the moving forces behind the canal was Colonel Proby Cautley , who was confident that a 500-kilometre canal was feasible. There were many obstacles and objections to his project, mostly financial, but Cautley persevered and after spending six months walking and riding through the area taking measurements, he managed to persuade
