How to combine the particle system with the plane?

Hi, I'm working on a project that study how rising sea-level affects the coastal environment. I have created a plane which refers to "Ocean Sea-level" and a particle system indicates the flowing water (the waves). Also, I have created a slider to control the height of sea-level. Now I want to know how I can combine the particle system and the plane together, that is, when I control the slider, the plane and the particle system will rise together, so I can show the water crashes onto terrain. Thanks a lot!!!!!!!
