Bastora Dam
The Bastora Dam or Goma-Span Dam is a gravity dam currently being constructed on the Bastora River at Goma span gorge, near Gomespan, in Erbil Governorate, Iraq. It is located about northeast of Erbil Erbil, also called Hawler (, ar, أربيل, Arbīl; syr, ܐܲܪܒܹܝܠ, Arbel), is the capital and most populated city in the Kurdistan Region of Iraq. It lies in the Erbil Governorate. It has an estimated population of around 1,600,000. H .... The primary purpose of the dam is water supply for irrigation but it will support a small 2.4 MW hydroelectric power station. It is expected to irrigate . Construction on the tall roller-compacted concrete dam began in 2013 and it is expected to be complete in 2023.

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the conc ...

Roller-compacted Concrete
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers.

Francis-type
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erbil
Erbil, also called Hawler (, ar, أربيل, Arbīl; syr, ܐܲܪܒܹܝܠ, Arbel), is the capital and most populated city in the Kurdistan Region of Iraq. It lies in the Erbil Governorate. It has an estimated population of around 1,600,000. Human settlement at Erbil may be dated back to the fifth millennium BC. At the heart of the city is the ancient Citadel of Erbil and Mudhafaria Minaret. The earliest historical reference to the region dates to the Third Dynasty of Ur of Sumer, when King Shulgi mentioned the city of Urbilum. The city was later conquered by the Assyrians. In the 3rd millennium BC Erbil was an independent power in its area. It was conqureed for a time by the Gutians. Beginning in the late 2nd millennium BC it came under Assyrian control. Subsequent to this, it was part of the geopolitical province of Assyria under several empires in turn, including the Median Empire, the Achaemenid Empire ( Achaemenid Assyria), Macedonian Empire, Seleucid Empire, Arme ...

Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Dams In The Tigris River Basin
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
