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 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 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.
When was Lake Darling Dam created?
Lake Darling Dam was created in 1936.

What lake is Hoover Dam holding back?
Lake Mead is the reservoir lake formed in Arizona and Nevada by Hoover Dam.
What lake is made from the headgate rock dam?
There is no Lake formed by the Headgate Rock Dam. It is just a diversion dam with a powerplant.
Is pressure lower at the bottom of a dam?
Density of water per unit volume ie. g/cm3 * depth of water (cm). Answer will be in g/sq cm. Density of water is approximately 1g / cm3 therefore pressure at the bottom of a dam wall with 1m of water = 0.1kg / sq cm. Note: this is only valid at the bottom of the wall, half way up the 1m of water the pressure would be 0.05kg / sq cm. At the very surface of the water, there would be no pressure. Thats why a finger in a dyke (dike) can hold back the North Sea!
Is Lake Mead and Hoover dam the same Lake?
The Hoover dam is at the end of Lake Mead. So they are not the same thing.
What do you call the lake that forms behind a dam?
what do you call an artificially body of water that forms behind a dam
Why dam pillar are wider at the base?
pillars with wider base support more load
