University of Salford academics have published a study, which shows that the flow of fresh water to Iraq via the Diyala River has been depleted by man-made regulation at its source in Iran, and have called for a treaty to protect Iraq’s water supply.
The Diyala River forms a natural border between Iran and Iraq for around 20 miles. It flows from Iran’s Zagros Mountains into eastern Iraq and joins the Tigris near Baghdad.
The new research shows that there has been a sharp shift in the flow of the Diyala during the last 15 years which cannot be attributed to climate change and dry spells alone. The reduction correlates with the building of dams, large-scale irrigation schemes, fish farms, and the industrial and municipal use of water upstream in Iran, causing the dwindling of the river’s flow into Iraq.

The City of Hoover has seen enormous growth in its sports programs over the past 10 years and needed a new complex that would fulfill their existing needs, allow for growth and give the City the ability to create new revenue streams and take advantage of sports tourism by hosting large tournament events. Hoover had not built any new athletic facilities in 15 years. At the same time the City’s sports participation had increased by multiples of 200% - 500% depending on the sport. The growth was caused by increases in both youth and adult sports leagues, as well as the relatively recent popularity of additional sports.
The multi-purpose Finley Center, which connects to the existing Hoover Met baseball stadium with a covered walkway, is able to accommodate a full-size football or soccer field, nine regulation-size basketball courts, 12 regulation-size volleyball courts or six indoor tennis courts. It can also seat 2,400 for banquets and 5,000 for events with general seating, such as a graduation ceremony or concert. Additional features of the indoor facility include a recreational walking track suspended 14 feet in the air, an athletic training and rehab center, and a food court.
The Finley Center sits on a 120 acre site that GMC master planned and includes fields for soccer, lacrosse, football, baseball and softball, tennis courts, a play ground walking track and splash pad.

Colon City to Panama City, Panama
Constructed 1904-1914
The United States became interested in a water route through the Panamanian isthmus in the mid-1850s, but it was the French who first attempted to build the Panama Canal. Led by Ferdinand de Lesseps, builder of the Suez Canal in Egypt, the French began the project in 1876. Conditions were brutal: rampant yellow fever and malaria; massive landslides and flooding; sweltering heat; and construction equipment that was too light for the job.
In 1898, with a little more than one-tenth completed, the French started negotiations to sell the project rights to the United States. Congress authorized the U.S. to complete the Panama Canal, and construction began in May 1904. American engineers, including John Frank Stevensand Col. George Washington Goethals, faced many of the same challenges as the French, but succeeded by implementing a truly monumental construction plan.

Truth or Consequences, New Mexico
Constructed 1916
"Water from the Rio Grande Project, coupled with improved farming methods, has transformed a formerly desert-like region into a lush, productive landscape. Astronaut John Glenn - as the Mercury capsule Friendship 7 reentered the earth's atmosphere in 1962 and passed over New Mexico - described the project area as a ribbon of green extending straight north from the Mexico border."
- Bureau of Reclamation brochure, 1982
One of the first major efforts to increase farming and encourage habitation in the arid regions of the western United States, the Rio Grande Project was designed to provide reliable irrigation as well as resolve a dispute over water supply with the Republic of Mexico. The project's centerpiece is Elephant Butte Dam, a concrete gravity structure 301 feet high and 1,674 feet wide. Elephant Butte Reservoir - with a surface area of 36,600 acres and a capacity of more than 2.2 million acre-feet - was the largest reservoir in the world at the time of its completion.
Today, the Rio Grande Project provides irrigation for almost 200,000 acres in New Mexico and west Texas along with 25,000 acres in Mexico. A pioneering accomplishment, the Rio Grande Project provided significant experience for many of its engineers, two of whom - Arthur P. Davis and Louis C. Hill-later served as president of the American Society of Civil Engineers.
Facts
- Initiated by the U.S. Bureau of Reclamation soon after its formation in 1902, the Rio Grande Project was the first in the world to distribute water across international boundaries. Under the terms of a 1906 treaty, the project provides water to the Juarez Valley of Mexico by means of the American Diversion Dam and Canal system, located 2 miles northwest of El Paso, Texas.
- In 1938, the Reclamation Bureau constructed a hydroelectric plant at Elephant Butte Dam and -- 25 miles downstream -- the project's second major storage facility, Caballo Dam and Reservoir. Today, water held at the Elephant Butte reservoir is used for winter power generation, then held at the Caballo reservoir for summer irrigation.
- The Rio Grande Project currently extends 100 miles north of El Paso and 40 miles to the city's southeast, comprising a total of two major dams, six diversion dams, 140 miles of canals, 460 miles of laterals, 465 miles of drains, a hydroelectric plant, 500 miles of transmission lines, and 11 substations.
- Among the crops grown in the Rio Grande Project area, "King Cotton" remains one of the most prominent, along with peppers, onions, and lettuce. Other crops include barley, alfalfa, and pecans.

Bristol, England
Built between 1835 and 1841
In the early 1830s, the merchants of Bristol, long dissatisfied with their communication with London, began to wonder if the new railroad technology might be a solution to their problem. The Bristol Chamber of Commerce, the Merchant Adventurers and other local industrial bodies formed a committee in 1833 to discuss the ambitious proposal of laying a railway to London. Matters progressed swiftly. Money was advanced and the search for a first-class engineer to guide the effort.
Isambard Kingdom Brunel, who had helped his father build the Thames Tunnel and who had been appointed engineer for the Clifton Suspension Bridge, was among the many applicants for the engineer-in-chief on the new railway. In March, 1833, the 27-year-old Brunel was chosen to superintend the construction of the Bristol-London railway, which in the same year adopted its Great Western Railway (GWR) as the corporate identity it would retain until consolidation into the nationwide British Railways system in 1948. It was the first major civil engineering work to be designed, directed, and completed by Brunel. Parliment officially established the company in 1835 and construction began the next year.
Brunel's route ran north of the Marl-borough Downs via Reading, Swindon, and Bath. He selected this northern course because it offered easier gradients and because it would readily allow later extensions to Oxford, Gloucester and South Wales. West of Reading he laid out the railway to follow the Thames River and pass through the valley of the Chilterns. For a distance of 77 miles the track would gradually gain elevation as it proceeded west to Swindon, never exceeding a gradient of 0.15 in 100 (8 feet per mile). From Swindon, the descent to Bristol was to be made over two short gradients of 1 in 100 (52.8 feet per mile). One of these would be in a tunnel through the Box Hill east of Bath.
Portions of the GWR opened as they were completed, beginning with the 24-mile London Paddington-Taplow section, which included the eight-arch Wharncliffe Viaduct, in 1838. Completion of the Maidenhead Bridge over the Thames, with its two, unusually flat, elliptical arches, allowed the line's extension to Twyford the following year. By December 1840, the railhead had reached Chippenham, where it crossed the center of town on another Brunel-designed arch viaduct. Almost appearing to be two separate structures, this viaduct includes six large and three small arches. While the railhead steadily advanced from the east, construction began onthe western section from Bristol to Bath, which also began service in 1840.
The last 24 miles between Chippenham and Bath - out of the total of 118 3/4 total between London and Bristol - were the worst. This final stretch contained the famous Box Tunnel, considered by many at the time to be almost impossible to build or operate through. Brunel believed otherwise, and he intentionally chose a route that required a tunnel through Box Hill to maintain the most-favorable gradients over the entire line.
Box Tunnel was a major feat in those early days of railway engineering. At 1 7/8 mile, it was the longest railway tunnel in existence. The bore measured 30 feet wide at the spring of its arch with a crown 25 feet above the rails. For construction access, and later ventilation, Brunel sank six vertical shafts 30 feet in diameter and varying from 70 to 300 feet deep, along the alignment of the tunnel. They permitted excavations to proceed simultaneously at fourteen working faces. During the construction of the tunnel, workers used a ton of gunpowder and a ton of candles every week. Having taken five years to build at an average cost of £100 per yard, Box Tunnel, along with the last portion of the GWR was finished in June 1841, and the ambition of the Bristol merchants to see trains running from London to Bristol was realized.
In Bristol, Brunel teamed with noted architect Matthew Digby Wyatt to design Temple Meads Station. Its Brunel-designed train shed featured a 72-foot-span hammerbeam roof structure-still the world's widest. Although superseded by a newer station, the original building and train shed survive as a museum and car park, making the complex the world's oldest purpose-built railway terminus. Other notable works still in service on the line include Box Tunnel, Sonning Cutting near Reading, Maidenhead Bridge, Wharncliffe Viaduct, and Chippenham Viaduct. London Paddington Station has been enlarged and modified over the years, but Brunel's 1854 three-span train shed remains essentially intact over platforms 1 - 8. These structures and the railway's overall alignment comprise a fitting tribute to one of civil engineering's boldest and accomplished practitioners.
