As indicated above the best way to create a waterfall effect is to use an FX, like in Cliffside.

There are 2 FXs to look at unless you are creating new ones:

Look in C:\Program Files\Activision\Call of Duty - World at War\raw\fx\maps\mp_maps

- fx_mp_water_fall_sm.efx <-- main FX of falling water
- fx_mp_water_fall_puddle_splash.efx <-- Bottom of waterfall FX

For adding the FXs to the map check out one of these 3 Tutorials:

TUTORIAL #1
TUTORIAL #2
TUTORIAL #3

Good Luck!
