to hold the water better but at the top it's thinner to get water in
Water pressure increases with depth. So in a deep lake the bottom of the damn needs to be thicker to accommodate the greater water pressure.
Because the water pressure at the bottom of the dam is much more than the top.
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.
The engineers.
i dunnobecause they are
they built dams to keep the flooding out of their cities
hydroelectric dams
Most large dams are built in the North, but small ones are mainly in the middle of pakistan.
dams
Yes there are many dams and more dams are being built. i dont know how many and i would like to know.
dames and barrages are built to store and redistribute water
Yangtze River in China has three Gorge Dams built. It is to keep the floods down and to keep the cities safe.
