In the design of a dam, the thickness of the wall is the same as the pressure of water remains the same.
In the design of a dam, the wall at the bottom of the dam is thicker as the pressure of water increases with depth.
In the design of a dam, the wall at the bottom of the dam is thinner as the pressure of water decreases with depth.
In the design of a dam, the wall at the middle of the dam is thicker as the pressure of water is highest in the middle.
