Why is the sea level written on railway stations? Water storage tanks are usually built on towers or placed on hilltops. Why? Why do beavers build dams? Why is Lake Victoria black? Why is the Chao Phraya River brown? Why does groundwater discharge to the Earth's surface?
Rivers are also a very practical way of transporting heavy objects or large quantities of trade goods. In Egypt, for instance, they used the Nile to transport the enormous blocks of stone needed to build the pyramids. Other common uses are lumber, ore and transporting industrial goods and reso...
says in her work she’s found that “sedimentation rates have skyrocketed in the 20th century, and a big impact has been the number of dams that are on rivers feeding into lakes.” When they do dredging or sluicing, she says, sedimentation rates shoot up ...

By instinct, beavers build dams. But all these dams follow the same pattern. The beaver cannot think out some new, different pattern and make some new and different thing. Ants may form ant hills; gophers, snakes and rodents dig holes; birds build nests. But they always follow the same ...

And that’s why most people in Los Angeles produce services for local consumption and therefore do pretty much the same things as most people in metropolitan New York—or for that matter in London, Paris and modern Chicago.” Few services can be mechanized or delivered from afar via the ...
Hydraulic or hydroelectric energytransforms the kinetic energy of water into electricity through hydroelectric plants. Like wind or solar power, hydropower is intermittent: it depends on the flow of water (dams, rivers, streams, etc.) and on rainfall. In other words, the drier the year, the le...
