Volume Blend-Altitude
The Volume Blend - Altitude modifier gradually blends in the Volume color based on Altitude. Areas at lower altitudes are tinted with the 100% Volume Color; as you move higher up, less of the Volume Color is added.
This modifier can be used to create a sense of depth in an infinite water slab. If you blend between a light Diffuse Color and a darker Volume Color, you can create the illusion of depth as you sink deeper into the water.

The images below show a water slab with the Volume Blend - Altitude enabled in the image on the right.
