How do I create a dynamic water running down a surface/Z-axis effect?

I’m trying to learn how to setup a material to act like surface/running water on an object.

On flat areas the water would appear to stay still… and the greater the slope angle the faster it would move down.

It should be possible to rotate the object in any direction and the water would still collect / flow down depending on slope.

Convinced I saw a tutorial on this type of material for UDK a long time back but Google is not throwing it up again.

any help, even an idea of the principle I need to achieve / useful nodes for the task would be appreciated. thanks
