Is there a word in English to describe the descent of water or fluid out from a source? [closed]

I'm looking for a word to describe the flow of a liquid downwards gently and continually from a source.

E.g. water being shot up from a jet fountain and then bending and flowing downwards.

Lava flowing out of a volcano.

See images.

Solution 1:

A good one is Cascade

What wonderful pictures you have.
