Dams are problems or solutions creators?
First… What is dam?
A dam is a large wall or barrier that blocks or stops the flow of water, forming a reservoir or a lake.
Most dams have a section called a spillway over which, or through which, water flows, either sometimes or always.
Dams can be classified as single-purpose and multipurpose Dam.
Here are the different kinds of dams used and what they are used for.
- Gravity Dam. It’s a massive sized dam fabricated from concrete or stone masonry. They are designed to hold back large volumes of water.
- Arch Dams: An arch dam is curved in plan, with its convexity towards the upstream side. An arch dam is quite suitable for narrow canyons.
- Buttress Dam.
- Embankment Dam. It’s a large artificial dam. It is typically created by the placement and … break the rock.
- Diversion Dam. It’s constructed for the purpose of diverting water of the river into an off-taking canal (or a conduit).
- Cofferdam. It’s a temporary dam constructed for facilitating construction.
- Storage Dam. They are constructed to store water during the rainy season when there is a large flow in the river.
- Detention Dam. They are constructed for flood control.
Gravity, buttress and arch are the three common types of concrete dams.
