Dams

It's waste of money sometimes.the noise sometime irritates.

Portage is just a technical word for "carrying it around because we can't go through here". Simply take the kayaks to the shore, remove all of the associated equipment and place it inside them, then find a path around the dam. Carry the kayaks along it until you are past the dam, then set up and paddle away again.

Hydroelectricity and tidal energy are similar because they are both sources of energy rely on water.

Because south india is nearer to equator than the rest parts of india, so it is easy to launch satellites and set in geo-synchronus orbit and reduce the cost by saving fuel.

The two names are referring to the same dam, so one is not older than the other.

Hoover Dam was named for Herbert Hoover, the 31st US President.

According to the Bureau of Land Management website, the name of the dam built as part of the Boulder Canyon project was always "Hoover Dam". That was stated by the Secretary of the Interior on Sept 30, 1930 when construction started and the name was made official by an Act of Congress on February 14, 1931. The name "Hoover Dam" was never officially changed. It was political pettiness that perpetuated the names "Boulder Canyon Dam" and "Boulder Dam".

In 1947, resolutions were passed in the House and the Senate and signed by President Truman to restore the original name.

Glen Canyon is approximately 710 feet deep, or approximately 220 meters deep. The canyon, with the Glen Canyon Dam, can hold 5,370,000 cubic yards for water.

There are three major types of galleries in any dam structure. 1. Service galleries which are used for piping for fluids such as water, hydraulic oil, and compressed air to operate lock and spillway gates, as well as conduits for electrical wiring, networking cables, telephone and communication lines. 2. Pump galleries these are located in the foundations of dams, and contain submerseable pumps to "dewater" the dam, or remove what water seeps into the dam structure. 3. Observation galleries, these are used to extract soil samples from under the dam foundations as well as to check on the integrity of structural components such as rebar used in the construction. Most generally galleries fall into multiple different combinations of these, and are also used as simple pedestrian tunnels for the gate operators. These galleries also will contain things such as fire alarms, fire sprinkler systems, and electrical lighting.

A large hydropower dam on average costs 1800 million in 2010 USD with an average installed capacity of 630 MW.

A reservoir is a body of water kept at a controleld level, usually by a dam. Dams gnerate electricity via the movement of water. Aqueducts are open 'pipes' that exploit gravity to induce water flow

An adit is a horizontal tunnel used in mining. They're not directly related to dams but in the construction of Hoover Dam a number of adits were used to facilitate the construction of the various tunnels associated with the dam. For example, adits were cut into the center of the canyon for the diversion tunnels allowing the tunnels to be cut faster; instead of just two work faces (upstream and downstream) an adit was cut and work started in the middle. That allowed four working faces on each tunnel: upstream portal, adit to upstream portal, adit to downstream portal, downstream portal.

The tunnels in the dam (what you see on the "low side" of the dam) dont produce electricity. These are the 'outflow' channels for water that is exiting a turbine (which is what generates the electricity). The weight of water behind the dam forces it down a tunnel to a turbine where the water pressure spins the turbine, which generates electricity. The water, once it passes through the generator, goes out a tunnel to a river below the dam. This is typically the water you see coming out from under a "hydro-electric" dam. There are also spillways to let excess water out from the reservoir (high side) behind the dam if the water gets too high.

to allow wast to settle out naturally

The dam is 1.3km and also it's impermeable cause it's made of clay...thx if u read ma answer it's 4 the ones who want the answer...x

Because water pressure is greater near the surface of the water

We would all dieee ..

71 more are going to be built by 2017, including the infamous Belo Monte dam.

Cause in Netherlands (Holland) they have many dams and city are named with dam at the end of their name. So they named their ships after cities, dams, and of points of compass.

The Rogun Dam is located in southern Tajikistan on the Vakhsh River. Tajikistan is located in Central Asia and borders with Afghanistan to the south, China to the East and Uzbekistan to the West.

Depends on how big i can build you one for around 55,000$ a small one but.

Because the "backroller" is part of a recirculating current which can hold an object (you) against the face of the dam. If you approach too near the "boil line", even from apparent safety downstream, the current may pull you in (yes, pull you UPSTREAM) and you may never escape.

Unwary boaters, fisherman, etc. drown in these currents every year, and many professional rescuers have lost their lives trying to save them.

Ardnacrusha and Poulaphouca in Limerick and Wicklow respectively, and there are Cathlene's Falls, Cliff, Golden Falls, Iniscara and Leixlip Lake.
