car tires throw water splashes

Hello, how I can create a collision script between car and water when car and water are in collision to activate water splashes (game object) at the wheels only when the wheels of the car are in motion.
I attached a picture to what I mean, water (water splashes) to jump from the wheels.
I have been trying for two weeks to do this but I have not succeeded, please help me. Thank you !

Flowing water is a river is not a plan

I would like to get something like this: (only water splash particles, because the waves assume that they cannot be obtained on a river but only on a plan, could be obtain it but it's a lot of work, so I'm pleased with water splashes)

My problem is that I don't know how to do scripts so I posted here in the forum, maybe someone can help me

 

Pic not working for me.

Is the spash a particle system?
If so just use the emission over distance thingy.
Could also use a script to check for motion and call "Emit()" on the PS/whatever your using.

Provide more info about your setup if you want more help

 

Yes , it`s a particle system
