How to make a nice waterfall

Ok,waterfall is not much complicated but it is not advanced and won't look as you think it would. First of all you must have a ready mountain that you want to make water fall from over it,to make it look like reality,add some water like a pond or a river on the top. Then go to the front side of the mountain(the pond must be connected to this side) and simply make a big hole by scrolling the wheel(while selecting from the top of the mountain to the downside of it) or to make it look better use the same way you made the mountain with (h button).And now while still selecting the part you made now press f3 and fill it with water.then make a pond under the mountain so that is will look much better.
