Due to the that the pressure exerted by a liquid increase with its depth. Thus as depth increase, more and more pressure is exert by water on the wall of dam. A thick wall is required to withstand a great pressure, therefore, the wall of the dam is made with thickness increasing towards the base

Why are dams over rivers are made broader at bottom than at the top?
The pressure of the water (the weight) is greater at the bottom, due to the depth of the water. As the pressure is less near the top, the top of the dam wall doesn't need to be as thick as the bottom of the dam wall.
Why are dams built stronger and broader at the bottom?
Because water pressure is more intense at depth than it is near the surface - hence the dam has to be stronger at the bottom - it withstands more pressure at the bottom.
Why is the base of a dam thinner then the wall?
The pressure against the dam wall increases at the lower levels than nearer the surface. So I expect the foot of the dam wall to be thicker at the bottom than at the top.
Why do dams need to be thicker on the bottom and thiner at the top?
because the water pressure on the damn is much higher on the bottom of it than the top.
Why dams must be constructed so that they are much thicker at the bottom than the top?
Because the water pressure at the bottom of the dam is much more than the top.
Why the base of the dam is made wider?
The pressure of the water against the top of the dam wall, is much less than the pressure exerted against the bottom of the dam wall. The width of a dam wall increases to compensate for the increased water pressures at the lower level.
Is the Hoover Dam the same thickness at the top as the bottom?
no, its thicker at the bottom
Is mangla dam the 6Th largest dam of the world?
yes, Mangla dam is 6th largest dam in the world.
Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
In a dam a hole is formed through which water flows. why will it be more difficult to plug the leak if the hole is located at the bottom of the dam than if it is at the top?
Because the pressure of the water is a lot stronger at the bottom of the water and a lot less strong closer to the surface of the water
