people who make dams include, fat people, skinny people and people that make no sense what so ever so if u think about it ur an idiot! btw my name is Garrett lucas and i use to work no damns!!!!!!!!
What dams can drive over in the US?
I have been told that the only two dams you can drive over in the US are The Hoover Dam in Nevada, and the Stevenson Dam in Connecticut.
What temple was moved when the Aswan Dam was built?
These are known as the Abu Simbel temples. From Wikipedia : "The complex was relocated in its entirety in 1968, on an artificial hill made from a domed structure, high above theAswan High Dam reservoir. The relocation of the temples was necessary to prevent their being submerged during the creation of Lake Nasser, the massive artificial water reservoir formed after the building of the Aswan High Dam on theNileRiver."
When was the Mangla Dam constructed?
As part of the Indus Waters Treaty signed in 1960, India gained rights to the waters of the Ravi, Sutlej and Beas rivers, while Pakistan, in addition to waters of the above three rivers within Pakistan and some monetary compensation, received the rights to develop theJhelum, Chenab and Indus river basins through construction of the Indus Basin Project. Until 1967, the entire irrigation system ofPakistan was fully dependent on unregulated flows of the Indus and its major tributaries. The agricultural yield was very low for a number of reasons, the most important being a lack of water during critical growing periods. This problem stemmed from the seasonal variations in the river flow due to monsoons and the absence of storage reservoirs to conserve the vast amounts of surplus water during those periods of high river discharge.

The purpose of the surge shaft to damp surges in the headrace tunnel of the underground hydropower plant.
It dampens hammering in HRT and prevent it from bursting. It actually consist of an orifice, which helps in regulating the flow in HRT gradually.
A surge shaft is one of the components of water conductor system of a hydr Power Plant. It is not a part in Dam but Dam can be one of the components of an hydro power Plant.
If you have a very high head hydro power plant with a water conductor system or so called HRT, Pressure Shaft and a Steel Penstock then a Surge Shaft is necessary to dampen the Water Hammer pressures immediately occurring due to the Load rejection cases which are frequent and are related to fluctuations in the load demand and other deficiencies or machine faults or line faults etc. Due to water hammer pressure the flowing water into the turbines gets rejected and the water starts travelling in the form of back pressure or oscillating waves with a very high velocity or celerity. This has to be dampened or else there is a possibility of cracking of penstocks or collapse of tunnel linings etc.
Can you cast human ashes off of Hoover Dam?
No, it is not legal to scatter human ashes off of Hoover Dam. The U.S. Bureau of Reclamation, which manages the dam, prohibits the scattering of human remains on their properties. Additionally, scattering ashes in bodies of water like the Colorado River can have negative environmental impacts. It is important to follow local regulations and consider the environmental consequences when choosing a location for scattering ashes.
How do you build a pyramid for school project?
A pyramid has a square base & 4 equilateral triangular sides. A tetrahedron is made up of 4 equilateral triangles. You can take cardboard and leave one side open and then put things on the inside to make it look like a real one.You can make it out of a lot of different things like marshmallows, card board, sugar cube, and a lot more. I am doing a project on an Egyptian pyramid and i am trying to make it out of marshmallows with one side open.

Does Hoover Dam have floodgates?
The Hoover dam has two spillways, one on the Nevada side and one on the Arizona side. The spillways are located 27 feet below the top of the dam, one on each side of the dam. Any water getting up that high will go into the spillways. There are "Drum Gates" in the spillways, but these are actually there to allow more water to be stored behind the dam. When they are raised they can allow an additional sixteen feet of level to be stored behind the dam. The spillways have only been needed twice in Hoover Dams history. The first time was in 1941 to test the system. The second time was in 1983 for an actual flood.
What are some of the pros and cons of reservoir and dams?
A Pro of having a reservoir is that it gives nearby towns and villages water, a con to a reservoir is that You have to flood the animals habitats that lived on the land.
What was the reason the Hoover Dam was built?
It is a water reservoir that supplies hydroelectric power and water for recreation, municipalities and irrigation as well as flood control.
The Hoover Dam provides electricity to all of the towns and cities in AZ, NM, SoCal, NV, UT, & Colorado.

the pourpose is to create eletricity for the towns nearby
to stop the area from flooding and to produce energy
When does quabbin reservoir close?
Depending on the time of year, all motor vehicles had to be out by either 4:30 5:30 6:30 or 7:30.
Dams are not just bad. They are disastrous. The reasons are multiple and complex. It really begins by saying that a river flows to its delta before reaching the ocean for a reason. The reasons for this flow to be unheeded are vastly important and concern all of us. Dams actually threaten the integrity of land mass because river deltas accumulate enormous quantities of silt. In the case of the Colorado; this would have been from erosion in the rocky mountains and all those famous canyons. This silt and sediment carried by the river is more precious than gold because so much life depended upon it. It might seem to us on a muddy river that it looks lifeless but that silt and mud are maintaining the health of the planet. To take the example of the Colorado river.
The hoover dam was completed in the 1930s and for 6 years almost no flow reached the enormous river delta. At this point the river would have deposited enormous quantities of silt and sediment. The delta itself was vast and acted (as all deltas do); like an enormous sponge. It absorbed and purified the river sediments and created vast wetlands were the river flow branched into countless lagoons. In the case of the Colorado river there were woodlands full of native cottonwood and willow. Deer and jaguar were part of the ecosystem as well as brackish water species of fish which only existed in the Colorado delta. Spring floods naturally cleansed the wetlands of salt and enabled native trees to take root.
For 70 years now the river delta has slowly dried to a caked desert in many places. IT is difficult to imagine the suffering caused in the 1930s when lake mead slowly filled and the river delta lost its vital nutrients and fresh water flows from the Colorado. It is difficult to comprehend what happened at that time as the ecosystem went into decay and decline. A simple look at the Colorado river delta today from Google earth is testament enough to the death of the once vibrant jewel of life.
Lake mead behind hoover dam is an incongruous body of water. Where the Colorado enters lake mead silt has now accumulated to a depth of 80 metres. Why is this important?
The silt that washes down from the mountains and canyons contains natural concentrations of heavy metals such as selenium. These would have been washed down into the delta were they would have been naturally broken down by unique biological processes that only occur in river deltas. This increasing concentration of heavy metals behind the dams of rivers that once flowed naturally is a growing problem. Many people and cities that wouldn't have existed without the river being dammed rely on the water in the reservoirs for drinking. The increasing sediment from the rivers entering vast bodies of water being deposited is a subject that seems to have no voice. An ever growing level of sediment in the catchment lake is an issue that dam engineers and governments who give the go ahead for these massive projects - seem to be in denial about. But just how much sediment does a river deposit?
The numbers are impressive. It seems that the pivotal role of a flowing river is the release of nutrients along its course and within its delta. The sediment and silt contain these minerals and organic elements that natural flooding would have enriched the land with. Often far above the river's natural flow in times of high flooding. Flooding is often an excuse for building a dam but the greatest irony is that flooding itself is often the reason why people have been able to live at the river's edge. The fertility of the soil on flood plains is without precedence for the simple reason that it floods and the river deposits life sustaining nutrients during that brief time. So where does all this sediment and wealth of nutrients end up in a river like the Colorado? It is dumped and settles to the bottom of lake mead far behind hoover dam and there it stays.
