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.

What was the purpose of the dams of the Nile River?
To control the river and flooding and produce electricity.
How people benefit from the dams along the Colorado River?
They prevent flooding and produce electricity.
What kind of electricity do dams create?
hydroelectric power They produce what is called 3-phase AC power.
What do dams do in a hydro plant?
Dams store up a large volume of water in a very sharp gravitational gradient. This is used to drive the turbines and electromagnets that produce the electricity.
What are three ways the Columbia and the dams help peoplke in Washington?

Civil engineers work with structural geologists to?
plan bridges, tunnels, and dams
How faults and folds influence construction of dams and tunnels?
Fault lines and land folds influence the construction of dams and tunnels by helping to decide where at in the land and run of the river the structure will be made, and also how strong the structure will need to be.
What is water mainly used for in nz?
electricity dams/hydro dams
What apparatus are needed to generate hydro-electricity?
Moving water (dams, rivers, tides) and turbines (like an electric motor in reverse) that will produce electricity when the moving water spins them round.
