Need Help!! Creating a Realistic Water Ripple

Hi I'm fairly new to 3d modeling so here is my problem. I am trying to create somewhat realistic water and have a block rise out of the water to create a rippling effect on the water's surface. Is there anyway to do this with a reactor or something? I am using 3D Studio Max 7 so if anyone could please help me out that would be great.

(if you all could be specific in your responses that would be helpful to, I'm new at this after all , thanks again)
