How come waterfalls don't dry up?

Question

How is their an endless stream of water upstream to keep the waterfall going everyday, especially in hot countries where there isn't much snow?

I was just looking at this video from a waterfall in a hot country. The water arises in mountains that are about 8000 ft high. There isn't much snow since its by the equator. How does so much get water get produced to run the waterfall?

Answer 1

The rivers that feed waterfalls are often fed by glaciers high in the mountains, or they receive the accumulated rainfall from an entire drainage basin that feeds into a river system. Many of them are a combination of the two.

Most of the time, it is sufficient to supply the river with a constantly renewing source of water to flow over the waterfall, but in some regions, or during times of drought (or climate change) these rivers, and the waterfalls on them can indeed dry up.

If the source is blocked, or drainage basin changes geographically, it is very possible for waterfalls to dry up, even on the mightiest, most permanent water courses on Earth (i.e. Nile, Amazon, Mississippi).

Answer 2

What supplies a river during the summer? Rain. Snow is no more than frozen water. The river collects all the rain from the mountain (which in tropical regions it can rain on a daily basis) by way of tributary streams that form no different than the watter flowing down your driveway during a storm. The water falls don't go on and off because some of the water may take days to weeks to reach the waterfall from when it first rained. That's how the river and waterfall remain fueled.

Answer 3

Many rivers are fed not just by melting snow and ice, but underground water supplies. These underground reservoirs can be under particularly hot and dry places (i.e. Las Vegas), and probably are not recharged much by rain water. This arid mountain waterfall was probably the result of the water table touching the surface of the earth in enough spots to continuously feed this river, and hence the waterfall.

Answer 4

snow is not the only source of water in rivers. any water that falls from the sky can and does end up in rivers. there is often an ungoldly amount of rain in these countries during the wet season, and some smaller rivers and their waterfalls will dry up during the dry season. generally though, a larger river implies a larger supply of water, and a larger supply of water tends to be more continuous throughout the year, or supply enough water to get through the dry season without incident.

Answer 5

the water comes from a lot of stuff not just snow. from rain,i mean it travels a long way so there are many thing that could add water to the river

Answer 6

Above answers pretty much cover it, however, waterfalls can
and do sometimes dry up.

Answer 7

Rain.
