Why is a dam wider at the bottom compared to the top?
A dam is wider at the bottom compared to the top to ensure stability and to withstand the immense water pressure exerted by the reservoir. The wider base provides greater support and distributes the weight of the water more evenly, preventing the structure from collapsing. Additionally, a wider base helps to anchor the dam securely to the ground, resisting potential sliding or overturning forces. This design is critical for maintaining the dam's integrity and safety over time.
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.
Why are the walls of dam thickened near the base?

Why do dams have a very broad base?
Dams must hold back water of a certain depth, determined by the height of the dam. The pressure exerted by this water on the dam is dependent in part by its depth, since the base of the dam must be able to hold pressures exerted by the weight of all the water above the base. Since the pressure is greater at the base, the dam is broader at the base.

Where is the Hoover Dam and how tall is it?
the hoover dam is in Nevada and it is 726.4 feet from the base to the road.
The depth of water behind the Hoover Dam in Nevada is 220 m what is the water pressue at the base of this dam?
water pressure at the base of the dam is (specific weight of water * depth)2158.2KN/m2
Why do dams have a broader base?
There are two main reasons for a dam's broad-base design, and both are explained by the fact that all materials have limited strengths. The only practical way to increase strength is by adding material. The first idea is that a dam has to support its own weight. The heavier a dam gets, the more material is needed at the base to support itself. Hence very large dams have enormous bases. The second idea is that the dam has to also support water behind it. The top of the dam is thinner because it does not have to support too much water; only the surface of the water needs support. But as the water gets deeper, the dam has to support all that water above , and then its own weight. At the bottom, the dam has to support all the water and its own weight. This means that as you get lower, the dam has to get stronger. And as mentioned above, the only practical way to do so is to add material.
How does base of support influence stability?
The wider your base of support, the steadier you are.
