Aqueducts

BLOG 49

Although the Romans are considered the greatest aqueduct builders of the ancient world, qanāt systems were in use in ancient Persia, India, Egypt, and other Middle Eastern countries hundreds of years earlier. Those systems utilized tunnels tapped into hillsides that brought water for irrigation to the plains below.

Aqueducts were a vital aspect of society in ancient Rome, channeling fresh water from remote sources to city centers. Although aqueducts had been in existence before Roman times, it was the Romans who turned them into incredible architectural marvels, with impressive arched bridges and complex internal structures that could span across the territories of Rome. Many of these aqueducts have survived for thousands of years, a testament to the wonders of Roman engineering. Let’s take a look through some of ancient Rome’s most famous aqueducts that are still in existence today.

 

Pont Du Gard, Nimes

The Aqua Virgo, Rome

The Aqua Virgo has an important place in Roman history, as one of the first aqueducts to bring water into the city of Rome. It was originally built in 19 BCE by Marcus Agrippa during the reign of Emperor Augustus, and underwent various restoration projects throughout the centuries to keep it standing strong. Although it fell out of use following the fall of the Roman Empire, it was renovated during the Renaissance to transport 80,000 cubic meters of fresh water into the Trevi Fountain in the center of present-day Rome, and it continues to perform this role well today!

Buffalo Canals

Blog 48

This historic map of the Buffalo harbour shows where the Erie Canal once flowed.

For several years, teams of UB archaeologists from the Buffalo Archaeological Survey have conducted digs in downtown Buffalo along what was the Erie Canal. The artifacts they’ve found, when considered together, help describe how Buffalonians lived and worked from the early 1800s onward.

They’re conducting a “public outreach dig” under the Skyway and invite you to come down on Aug. 18 and 22, from 9 a.m. to 4 p.m., to visit the dig site, observe its operation and speak with the archaeologists and historians working there.

The site is bounded by Main Street and Hanover Street, east of the Skyway Pier. Hanover Street runs between Marine Drive and Prime Street.

The project manager, historian Nathan Montague, is a research support technician in the UB Department of Anthropology, which houses the survey. He is directing the dig as part of the Erie Canal Harbor Development Corp.’s Canalside Visitor Experience program.

Its mission is not only to excavate the area, but to educate the public about the canal and canal life, generate interest in the canal excavation and restoration work, and help people understand the work of archaeologists in general.

“We’re in the early stages of excavating this dig site,” he says, “ but previous digs we’ve conducted nearby have uncovered pipe stems and other personal items, dinner plates, commercial objects, a lot of brick and mortar, coal dust and ash, and something that could be a cannonball or part of a ship’s ballast. We will probably find similar items and even may find a few surprises.”

During much of the 19th and 20th centuries, Buffalo was a major international industrial and grain transport city, largely because of its waterfront and the Erie Canal, which cut a swath through what are now downtown streets.

“The canal was right downtown, so there was a great deal of commercial activity along this stretch of the waterfront for the better part of two centuries,” Montague says.

The canal’s main body, plus its many slips and adjuncts, covered a lot of territory. It ran southwest parallel to the harbor and ended at the Commercial (Street) Slip, where it met Lake Erie and the Buffalo River. Most of the harbor section of the canal was filled in by the 1920s, which is why we don’t “remember” where it was.

“So this spot now looks like an abandoned field,” Montague says, “but four- and five-story brick buildings once covered the entire block of land on which we are digging.

“The lower floors of those buildings typically housed businesses like warehouses, wholesale groceries, taverns, insurance companies and hardware stores, while upper floors were used for lodging or storage. Most of the buildings likely were erected in the 1830s and the last ones weren’t torn down until the early 1970s,” he explains.

“Artifacts from the site will tell us the stories of the people who lived and worked here when the Canalside neighborhood was the center of Buffalo’s—and the nation’s—economy,” he says.

He says the dig offers the public has a unique opportunity to get a sense of the layout of this area and how it has changed dramatically over the past century, and to see how urban archaeology is conducted and what it has to teach us.

The Archaeological Survey is a not-for-profit research, contracting and applied archaeology institution within the UB Department of Anthropology. It has been engaged in cultural resource management projects for more than 30 years. The institution manages artifact collections and information about historic and prehistoric archaeological sites and buildings in Western New York.

The 1920's were a static period for the inner harbor, in between two periods of change. By this time, the "old" Erie Canal  was no longer in use, having been supplanted in 1918 by the Barge Canal. The waterfront was nearly completely built up by the D. L. & W Railroad, which replaced the old mercantile Central and Long Wharf areas. The D. L. & W. had opened its new passenger terminal.

Coming in the 1930's was the construction of the Memorial Auditorium. The old Erie Canal bed and Commercial Slip would be filled in. And the "canal district," the impoverished immigrant neighbourhood by the harbour with so much colourful history will begin to be demolished completely.

In 1959, the Buffalo plant of General Mills used all the wheat grown on 1.25 million acres of land, or 90,000 bushels per day. In 1961, a new mill was constructed, not for expansion, but to create efficiencies. The new milling method reduced the number of workers required for operation. In addition to its standard flour and cereal products, the Buffalo plant began to produce Wondra, a new flour. But the company had diversified and was deep in debt, so in 1964, significant cuts were made to the Buffalo operations. A milling unit was shut, reducing the capacity by 62%. Three hundred of 1,300 employees lost their jobs. Also in 1964, the iconic Dakota elevator was closed, reducing the company's storage capacity by one million bushels, negatively affecting flour milling. Despite this, Buffalo's plant was General Mill's largest.  



This is an ink, wash and charcoal map of a section of the Erie Canal in Buffalo. It shows part of Lake Erie, Buffalo Harbor, Ship Canal, a canal basin, Thompson’s Cut, a guard lock and seven bridges. The red lines indicate courses and distances. The blue lines indicate canal right-of-way. The map also shows seventeen streets in the city of Buffalo.

Date Original
1834

So in 1830 they started building the canals ans in 1834 there were ready?  

Questions:

  • How many canals have been built lately with our advanced technology that people can use?
  • What other events happen in those years? 
  • How many people were at that time employed in building these canals?

Erie Canal From Buffalo to Albany in New York State New York 363 miles

 Blog 47


 

Facts about Erie Canal

  • Length, Albany to Buffalo (original Erie Canal)363 miles
  •  Number of locks, 1825  - 83
  • Number of locks, present day - 57
  • Elevation change, Albany to Buffalo - 571 feet
  • Canal dimensions, 1825 Original Erie - 4 ft deep x 40 ft wide; locks 90 ft long
  • Canal dimensions, 1862 Enlarged Erie 7 ft deep x 70 ft wide; lock 110 ft long
  • Number of aqueducts to bypass rivers and streams 18  
  • Travel time from Albany to Buffalo, 1825- 5 days






The present society cannot even maintain it.

The Official History Possibly Incorrect:

Constructed in 1825, the Erie Canal is considered the “Gateway to the West,” as it connected the port city of Buffalo with other cities along the Great Lakes, as well as the port of New York City.

According to the Erie Canalway Heritage Center, travel from Albany to Buffalo took two weeks by stagecoach in 1825, but the Erie Canal shortened the journey to five days. The Erie Canal brought goods and passengers, which directly contributed to Buffalo’s prosperity in trade and helped support its growth in culture, architecture and the arts in the late 1800s and early 1900s.

The Canal helped Buffalo eventually become the largest inland port in the nation as well as the unofficial grain capital of North America, which led to the construction of the city’s famous grain elevators, now used to host live performances, events and historical tours.

Among the canal district there were also warehouses, businesses, saloons, shops, residences, and hotels supported by the business and tourism fostered by the canal.

In the late 1800s, railroads became increasingly dominant and complemented the canal in supporting Buffalo’s economic and cultural growth.

Buffalo’s outer harbor also played a significant role in the city’s economy and history. Located just outside of Erie Canal Harbor on the banks of Lake Erie, the outer harbor became home to “heavy manufacturers” producing cement, copper, steel, and other important materials that contributed to the city’s industrial growth.

The Outer Harbor factories also provided many blue-collar jobs, which helped contribute to the “hardworking culture and down-to-earth disposition of the region and its residents,” according to the Erie Canal Harbor Development Corporation.

While most of the city’s factories have since shut down, most Buffalonians will agree that the city’s blue-collar work ethic and gritty mentality remains.

Water Technology

Blog 46

Another fascinating technology used by the Romans was the water wheel (Noria) which is represented in 4th century AD mosaics from Syria. The noria is powered by the flow of a river and lifts water in buckets to fields or aqueducts. There remain a number of ancient Arabic water wheels along the Orontes River in and near Hama. These water works date back to medieval times and as late as 1985 there were about 80 in use along the river irrigating over 5000 ha. Today only a handful remain and those in Hama itself are tourist attractions for the city – ancient and elegant reminders of the long history of water management and transference in Syria.

 


Water management is an issue that weaves itself throughout Syrian and Mesopotamian history. Irrigation canals and water diversions have a long archaeological and historical record. As one example – royal inscriptions from 2500 to 2350 BC from Mesopotamia relate to how Eannatum the ruler of Lagash extended the Inun water canal and how disputes over canals and irrigated fields led to war between that state and the neighboring state of Umma.

The Romans were the great water engineers and managers of the ancient world. Throughout Syria there remain, sometimes in working order, examples of Roman water management. One type of Roman water work that is extremely abundant, and often still functional, is the Roman Cistern (Abar Romani). These are small excavated caverns, often lined with Roman hydraulic cement, that capture surface flow from the winter rains for use in the dry summer. They typically have a large stone cover to protect the water. There are at least 1115 of these cisterns in Syria. On a small road near Qatura northeast of Aleppo one such cistern sits beneath a set of Roman cave tombs and is still used by travelers.

The Aqueducts Of the Ancients

 Blog 45

During the 4500 years of South American pre-Columbian history, numerous civilizations emerged, mainly in the western coast and the Andean regions of South America, e.g., the Chavín, the Moche, the Nazca, and the Huari. Around 1530 AD, almost all of their former territories, people and knowledge formed part of the Inca Empire. 
 
This pre-Hispanic state featured the largest extension in America, with a population of about 15 million inhabitants of different cultures and languages, including territories along the coast and the Andes of Peru, Bolivia, Ecuador, Colombia, Chile, and Argentina. 
 
The Incas, who existed as an empire for approximately 100 years before the arrival of the Spanish, conquered or annexed almost every contemporary civilization in the Andes and adjacent coastal regions, and assimilated all knowledge they encountered, including hydraulic engineering technologies
The Cumbe Mayo archaeological site located near the Peruvian city of Cajamarca, features the ruins of a 9 km long Pre-Incan aqueduct, built around 1500 BC.
 The aqueduct collected water from the Atlantic watershed and redirected it on its way to the Pacific Ocean. The channel was excavated in volcanic rock and is 35 to 50 cm wide and 30 to 65 cm deep . Locally the channel follows a zigzag course, possibly to diminish flow speed and prevent erosion. 
 
Arguably, in order to be able to design and build a channel with such a precision, the master builder must have employed cutting and leveling instruments.
 

 Is this a form of Terra forming?
