Make a gameObject in your scene put your water sprite on it and a box collider, set the collider to trigger, use a script to scale the y of the gameObject, use a lerp or coroutine to ping pong the value, or add randomness if wanted, this will scale the sprite and collider. Use OnTriggerEnter2D and call the game over from there.
