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.
What is hydraulic height as it relates to a dam?
The pressure that water exerts on the walls of the dam is proportional to the depth of the water or you might say the height of the column of water from the base of the dam. The hydraulic height is the same as the depth of the water to the bottom of the dam.
Why the foundation of a building made wider?
Foundation of buildings are made wider because the area of foundation is increased to reduce the pressure exerted by walls.
Why is junction capacitance of collector to base junction is lower than base to emitter junction?
The collector base depletion zone is wider than the emitter base depletion zone.
What is the similarties between a dam and a levee?
From what I infer from conversations between myself and some engineers in the local area, a dam and a levee both holds water to a confined space but, a dam is man-made while a levee is made of natural stuff. However, that is the extent of what i know in that.
Why dam pillar are wider at the base?
pillars with wider base support more load
Why are the walls of dam thickened near the base?
why are the walls of a dam thickened near 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.
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!
Can a dam create an artificial base level?
Yes.
Why does a dam at the end of a lake need to be wider at the bottom?
Because water pressure is greater near the surface of the water
Why dams are made wider at the bottom?
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.
