Very carefully
More seriously, there are two main types of hydrolectric installations: Impoundment, and run-of-river (there's also electricity generation from the tides, waves, etc, but we'll leave those aside for now).
The impoundment types are probably what you're thinking of when you say 'hydro dam'. These are large dams which create a reservoir upstream. The water in the reservoir is then forced to flow through penstocks within the dam which direct the flow to where it can power turbines which are in turn used to generate electrcity. The dams themselves are usually concrete, while the turbines are usually metal.
The run-of-river type involves diverting water from a river and once again using it to turn turbines. The turbines are again usually metal. They can be housed in a building made of just about any material, and some of the older ones are quite pretty stone buildings etc.
You are most likely talking about how hydroelectric dams are constructed in China and around the world. First you must direct the current in the river by making a makeshift dam in front of the dam you are constructing and a dam behind the dam you are constructing. Then you create a tunnel to change the flow. Since you block the river from going to the dam construction site, it is dry and ready to be built. First you put a slab of concrete for the generators to sit. Next you put in the generators and turbines so you can create electricity. Then you build the structure with concrete. You also build intake pipes and pipes that go back into the river so the turbines can function properly. You also need to build an overflow system. The overflow system will have gates to open when there is excess water. You might also need to build a canal if it is a busy river full of boats. Finally you fill up the tunnel and blow up the makeshift dams.
a. Will the dam provide new leisure activities? b. How many jobs will building the dam generate? c. Will building the dam destroy natural resources? d. Is it right to build a dam here?
Science can be used to predict the effects of the dam on wildlife.
For static purposes, this is not a difficult task, for the equations relating the model to the full sized dam are linear.However, when dynamic behaviour is considered, then the relationship between model and full-size is not linear. Effects such as fluid flow - water hammer, and fluid oscillation must all be carefully understood.But maybe you just want to make a model of a Beaver dam!
yes
In simplest terms, although running water is free, harnessing it is an expensive proposition.To effectively harness water, you must first confine and direct it, usually by means of a dam. Since dams can cost hundreds of millions of dollars, this is a very expensive proposition.The Hoover dam (known initially as the Boulder dam) cost $49,000,000, and that was in 1936 dollars, when a new car cost less than $600!Dam-building is also a very dangerous venture, which further drives up the cost; the Hoover dam mentioned above cost almost 100 lives.
hydro electic is a power source but you have to build a dam
Yes you can, however, the logic is not to expand an existing hydro dam (which is not very practical) but to build additional dam or dams on the same water streamline.
You would have to build a dam, which could mess with the flow of the river.
Wellington Dam Hydro Power Station was created in 1935.

Possibly not the best phrased question however you could say that a hydro dam is a dam that's primary function is the generation of hydropower. I note that under the heading of dam there are links to a hydropower page.

The Tampa Bay Hydro Dam is a way for the city to benefit from hydropower. This can greatly benefit the city and residents as it is a renewable resource.
Malampuzha dam in Palakkad district is the biggest dam..... But it is not a hydro electric project.
yes in a hydro dam
at a hydro electric dam
yes
