How does a waterfall keep dumping such volume of water to a lower place without stopping?
In: Physics
It’s being replenished at an incredible rate upstream. A little watercourse in a valley is gathering all the rainfall from the surrounding hills and concentrating it. If its a huge fall, it might have a ‘catchment area’ that spans hundreds or thousands of square kilometres. Every little stream feeding into this one brings more hills into the fold. This process might take days for the water to work it’s way down, so the stream and falls can be high even if it’s currently dry
The way water pressures and speeds work the waterfall’s volume/time is dependant on how much of this rain is coming in. It will die back in dry seasons and then grow in the wet ones.
