Dam Information
Here are a few dam things:
A dam's design must enable it to withstand greater pressure at the bottom than at the top. As a result, many dams are built in a triangular shape. The wide bottom withstands the great load of the water deep below the surface, while the thinner top of the dam need not use unnecessarily costly materials. Hoover Dam is 221 metres high and 201 metres thick at its base and has a partial arch effect. Glen Canyon Dam, which spans the Colorado River in Arizona, is the highest arch dam in the United States. It is 216 metres high and 475 metres long but contains less than four million cubic metres of concrete.
Based on this information you can see that dams are built tough, and built hard, so they can with stand a lot of water pressure in order to protect villagers down below. And it is dam hard to keep writing a blog...
