Dams

It caused extinction of river basin salmon and steel heads. also, After the dam was built the colville tribe's land flooded and were forced to move

I would contact your county extension agent for advice. One idea may be to dig down around your rusted pipe a few feet and slide another pipe over the top long enough to match where your overflow point should be. Be aware of your liabilities in knowing you could have a failure, and what damages could occur down stream with a dam failure. GL

Flooding

There are not so many dams because it will cost lots ,floods,we think that dams will help us in generations to come but that doesn't happen mostly and it will also destroy the habitats

There is no dam problem. Dams are carefully inspected several times per year and walk throughs are conducted by staff daily. Those dams that are found to be unsafe are fixed quickly.

Now, if you are talking about dam builders, then yes, they are a problem sometimes. Beavers are prolific dam builders. These rodents can be a nuance to property owners and farmers with their dam building and flooding of perfectly good property. A couple of good busy dam beavers can soon turn acres of arable land into a real swamp. Just try to break one of their dams, the dam beaver are rebuilding the minute you turn your back, sometimes they are working to repair the dam at the same time you are breaking the dam. You might say they are dam persistent. Then there's the Tinker's dam. In the olden days, pots were literally made of tin. Since it was a relatively cheap material, the itinerant tin smith would regularly come through the neighborhood to repair these pots and pans. Using a bit of clay, he would make a "dam" of it around the hole. Given that tin is liquid when melted, the tin would be poured into the hole and the dam would stop the spread of the tin to the whole outside surface of the pot. It made a convenient patching process.

But the dam, after it was used, was totally useless. It couldn't be used for clay any more because it was contaminated with the tin, so it was thrown away. So the expression "I would give a Tinker's Dam about it" was born for something totally useless. Dam problems can be interesting, can't they?

Nope. No sailing.

Natural Hydrodynamics. Same as in all birds nature has crafted them in a wedge shape for better movement through water or air.

The Hirakud Dam project is built across the Mahanadi River, about 15 km from Sambalpur. This is in the state of Odisha in India.

The Mica Dam is 80 ft wide; 178 ft high; 778 ft long.

CCTV or Closed Circuit Television placed strategically in a water dam can monitor the dam for damage. The dam has many places that are unsafe for a human to monitor, so the CCTV is a valuable tool.

Construction on the Itaipu Dam began in January 1970 and the dam officially opened on May 5, 1984. The Itaipu Dam is a hydroelectric dam located on the Parana River on the border between Brazil and Paraguay.

The building of the dam was funded by the Soviets who in June 1956 offered their loan of $1,120,000,000 at 2% interest for the construction.

OK so listen i m telling that i don't know what the answer is . i am asking everybody and this Internet is blabbering to me . it is also of no use nowadays

Grand coulee dam was finished on June 1, 1942.

When a dam is to be built, a diversion tunnel is usually bored through solid rock next to the dam site to bypass the dam construction site. The dam is built while the river flows through the diversion tunnel.

harnessing water flow to drive turbines and electric generators

The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.

TMC is a measurement of volume. It is an abbreviation of Thousand Million Cubic feet. This is equal to 283.17 megalitres.

TMC =Ten Million Cubic feet Million = 1000000( In new SI-International system -Mega-M)

Ten Million=10000000 1 feet = 12X 2.54 cm =30.48cm =0.3048m

1 cft = 1 feet X 1feet X 1feet = 0.3048 X 0.3048 X 0.3048 metre cube (m3)

1 m3 = 1/(0.3048 X 0.3048X0.3048) = 35.31466672 cft

1Mm3 =35.31466672X 1000000 cft

1 Mm3 =3.531466672 TMC

1TMC = 1/3.531466672 Mm3 = 0.283168465 Mm3 nearly = 0.28317 Mm3= 0.28317X 1000 M litres

1TMC =283.17 Mega litres

Also known as Cyclopean Concrete, this is a variety of concrete consisting of large sized stones(Plums) with interstices filled with concrete. Used mostly in mass concrete works like concrete gravity dams
