Hydroelectric Dams and Floods

837 Words4 Pages
Hydroelectric dams are essential to preventing floods. Many of these dams are located in places that are bordered by water such as Mississippi and Ohio. Most dams are created to control river flow, improve navigation, and regulate flooding. However, some dams are built to produce hydroelectric power which is the case here (Smith).
How does hydroelectric dams work? There’s a power source that is used to turn a piece called “turbine” then turns a metal shaft to an electric generator, and that creates electricity. (Perlman) The mechanical energy converts to electricity so the water flows through the dams. It could also work without dams, which is a process known as diversion/ run-of-the-river. Meaning, some of the portions of the water from a fast flowing river can be diverted through a penstock to a turbine set in the river. (Anderson) Getting to the point, the dams works by converting the energy to electric in order for the water to flow to get to our homes.
There are a lot of pros and cons about these hydroelectric dams! Some of the pros are renewable energy sorces, dams can store rain water or water directly from the river, produces power, very few break downs and last but not least it controls flooding. These pros really help us out in a positive way. Then, there's always something bad with a good. The cons of the dams are causing the rivers to clog, it messes up natural seasonal changes in the rivers, the ecosystems could be destroyed, and dams are expensive.
There are three types of hydropower families: diversion, impoundment, and pumped storage.Some hydropower plants use dams and some do not. (Walker). The sizes varries in different sizes. For an example, a small system for a home or a small city. They're also names f...

...urn the hydropower water into electricity to power our cars, homes and devices. In the future the development of hydropower plants will create local physical pollution. For an example, industrial structures in natural settings!
Where are hydroelectric power plants located? The biggest hydropower plant is located at the
Grand Coulee Dam which is on the Columbia River in Washington. Over seventy percent of the electricity made in Washington is produced by hydroelectric facilities (Thomas). Hydroelectric power provides about a fifth of the world's electricity. The five largest hydropower producers in 2004 were China, Canada, Brazil, Russia, and the United States.
Hydroelectric dams have a positive affect on us and our environment. Without it we would not have water running to our homes. And we wouldn't have anything to prevent floods! The dams are very helpful to us.
