How does a rivers source constantly have water.
In: 262
Rivers do sometimes run out of water. The source of a river can be a combination of snow melt and ground water and of course rain directly in. But if you mean how can rivers run even after 3 months of hot sunny weather, the answer is snow melt and then ground water. There’s a lot of water in the ground at higher elevations that’s constantly seeking lower elevation and rivers cut into the ground deeper than the surrounding soil so they capture that water.
There is a secondary thing going on where larger rivers start to resemble something more like a long skinny lake too. They have so much water in them that they don’t dry out by evaporation, but their flow rate can drop substantially to the point that they are barely emptying out into the ocean or wherever they end.
