How in the hell are dams built? Not for school or anything but like, my brain hurts trying to think about it.
Y’all I think the government is hiding Moses or mouana like seriously tho

They use concrete and pour it and BOOM a brand new dam

Gravity dams are so named because they are held to the ground by gravity – they weigh a lot, and are typically made from concrete or stone. Engineers must de-water the river where the dam is meant to be built. This is done by diverting the river through a tunnel that runs around the intended construction zone.

Step-by-step explanation:

Streams and rivers have to be diverted to create a dry area to construct the dam. Small rivers and streams are usually diverted through a tunnel, or a channel that is constructed around the side of the dam. Soft soils and rocks are excavated to form the route, while harder rocks have to be blasted with explosives.

i don't know gravity?
