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.

Old Dams.

This old dam was built in the 1880s.

Lake Vyrnwy is a reservoir in Powys, Wales, built in the 1880s for Liverpool Corporation Waterworks to supply Liverpool with fresh water. It flooded the head of the Vyrnwy valley and submerged the village of Llanwddyn. Wikipedia.
