Wavelanding
Waveland is an advanced tactic similiar to wavedashing. Wavelanding is performed after a character jumps to his/her peak and descends. As the character is approaching the ground the player presses L or R, initiating an air dodge. The ground then stops the air dodge animation and begins a normal wavedash. This is especially useful for moving around platforms quickly and for getting onto the stage quickly.
Wavelanding returns in SSBB, with limited uses. It is performed by holding in a desired direction while air dodging very close to the ground. Unlike wavelanding in Melee, the length of the slide is not dependent on traction, but on character air speed
Wavedropping
A Wavedrop is a useful technique when trying to mantain control while you're falling falling. To Wavedrop, you must jump, fall from a completed Aerial attack or from a DI and hold the control stick down. Then Air dodge as soon as you land on the ground. You will land in a Wavedashing animation. It's just like Wavedashing except you don't move in any direcion at all.
