Answer 3

On rivers! :-p The ideal locations permit a large vertical drop in water level (hydraulic head) between the upstream inlet to the outlet downstream, and a large volume flow rate. For small hydro applications, this usually means a steep section of river (ideally a waterfall) that allows a lot of head without the inlet and outlet being too far apart. Small hydro rarely can handle a river's full volume flux, so the size of the river matters little.

As for large hydro, dams and dikes can be used to create a reservoir, which builds head as it fills. Deep canyons with narrow outflows often lend themselves quite well to this purpose, as little damming is required to form a deep reservoir. Large hydro stations can usually dump water through the turbines as fast as the river can fill the reservoir, so bigger rivers yield more power (ceteris paribus).

Of course, there are other considerations. Seasonal variations in flow must be considered, especially if there is no reservoir to store springtime melt-water for the dry season. Will the station endure extreme temperatures? How about shifting sediments? Seismic activity? If so, it must be built to do so.

As much as the environment can affect hydropower stations, large hydro can also significantly impact the environment. Rivers shape the geography and support entire ecosystems, as well as human settlements. These effects should be considered when planning such a project.

Hydroelectric dams can serve several purposes other than power generation. They have been used extensively for flood control, and can provide a controlled flow of water for irrigation. Reservoirs are often wonderful recreational waterways. The for major dams on the Colorado river both host such reservoirs and contribute to the remarkable irrigation system that feeds agriculture in Arizona and southern California.
