How to make a "swimming pool water" effect?

Hi, I would like to create a swimming pool. I know how to do the ocean modifyer, but I don’t know how to do a effect like this:

(yes, this was from google. :p)

I would also like to have the rippling effect.
Do you know any way to do this?

Thanks in advance!

(P.S. I hope this is in the right section, I can’t quite tell.)
