Question

what are dams how it is helpful for water flow throughout year

Answer 1

Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric powerproduction and river navigation. Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.

Answer 2

Where does your water come from? Mountains, rivers, reservoirs? What is a reservoir? A reservoir is a human-made lake created by building a dam. Why do we need dams? When you turn on a faucet at home, where does that water come from? Why is there always water coming out? There is always a supply of water because we hold water in reservoirs. To do this, we must build dams.

Why else do we build dams? (Take suggestions; write answers on the board.) Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation. Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering. Dams and their reservoirs provide recreation areas for fishing and boating. They help people by reducing or preventing floods. During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow, when natural flows are inadequate to meet water demand. When engineers design and maintain dams, they consider all these purpose.

For the next several lessons, you are going to be civil engineers working for the company Splash Engineering. Your main client is the government (also known as a "municipality") of Thirsty County. The government of Thirsty County has been receiving complaints from its residents over the last decade. The main problems include:

Not enough water for people during the summer droughts.

Farmers have trouble growing food without enough irrigation water.

During drought periods, the Birdseye River is not deep enough for ships to cross to bring valuable goods to Thirsty County.

Flash floods ruin houses and stores.

Air pollution from a nearby coal-fired power plant makes people sick.

The Thirsty County government has hired the Splash Engineering firm (your class) to study the needs of the community and develop a solution that addresses those needs.

hope it helps u mate...
