Dams

Normally they would build a dam over a valley with a high amount of rainfall per year, this then would collect behind the dam and gradually get bigger. The river basin will ensure new tributaries and branch off and may eventually lead into the valley (valleys are made by rivers normally from the past) so the gravity will pull it into the easier path downstream towards the dam. While building a dam the company would normallu install a hydroelectric power plant to ensure the energy is put to good use. Hope that helped. It happens in some cases.

That would depend on the dam - specifically, the amount of water that flows through, and the difference in height that can be obtained.

Potential energy is calculated as: PE = mgh; in SI units: potential energy (in Joule) is equal to the mass (in kg) times the gravitation (9.8 m/sec square) times the height (in meters); you can use this to calculate energy.

If you are interested in power, assume that a certain amount of water flows through every second - the result will be Joule / second, that is, Watts.

Dams are primarily used for water supply. The Central Valley produces and incredible proportion of the nations fruits, vegetable, and nuts. Irrigation is required to grow these resources. Dams for artificial lakes that provide additional storage that may be released during times of greatest need. Power generation is a side-benefit, but water supply for farms (and cities, although the amount of water consumed by farms in the central valley is much greater) is key.

They are not bad at all, generally speaking. Dams prevent sudden rainstorms in the mountains from becoming flash floods in the lowlands, and we can use the water power to generate electricity; electricity that would otherwise require burning coal or natural gas to make. (Since you're using a computer, I'm assuming that the alternative of not having electricity isn't really an option to you.) Dams allow the river flow to be regulated more constantly, instead of being floods in the spring and dry in the summer.

Nothing is all good or all bad; building a dam causes water to back up behind the dam, flooding the valley. If there were towns there, the people are forced to move away. River fish, such as salmon, cannot pass the dam swimming upstream to spawn or downstream to the ocean without special "fish ladders". If the dam were to break, it would release a flood downstream; this has happened only a couple of times in the USA, but happens occasionally elsewhere in the world.

Most large dams are built in the North, but small ones are mainly in the middle of pakistan.

Hoover Dam is 1244 ft (379 m) long.

A dam controls flooding by regulating water flow in rivers and reservoirs, storing excess water during heavy rainfall and releasing it gradually to prevent downstream flooding. However, if a dam is poorly managed or experiences structural failure, it can cause flooding by releasing too much water suddenly. Additionally, if the reservoir behind the dam becomes full, it may lead to controlled releases that can overwhelm downstream areas, resulting in flooding. Proper management and maintenance are crucial to balancing flood control and risk.
