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.
the reason is because its more important food ( health wise ) than the top
Natural Hydrodynamics. Same as in all birds nature has crafted them in a wedge shape for better movement through water or air.
A funnel resembles a frustum of a cone, which is the portion of a cone that lies between two parallel planes cutting it. The shape tapers from a wider opening at the top to a narrower opening at the bottom, much like a funnel. Additionally, it can be likened to a truncated pyramid, which also has a wider base and a narrower top.
Numerator on top; denominator on the bottom.
the top adds what the bottom adds. the top subtracts what the bottom subtracts. the top divides what the bottom divides. the top multiplies what the bottom multiplies.
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.
no, its thicker at the bottom
because the water pressure on the damn is much higher on the bottom of it than 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.
The Nurek Dam in Tajikistan is 714 meters at the top and 1,420 meters are the bottom. It is an earthen dam across the Vakhsh River.
there are mums down there
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.
Because the water pressure at the bottom of the dam is much more than the top.
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!

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.
you measure at the top. Typically, pie pans are 8 or 9 inches.
