Well, water can be manipulted in two ways. You either breath in a lot of air into your lungs, while molding it with your chakra, creating fuuton that can be shape manipulated, then exhaled, creating a powerful wind blast, or channel your chakra around you, swirling it manipulating the air around you to create gusts of wind, or even powerful hurricanes.
Alright?
Now, I'd like you to channel your futon chakra around you, creating a gust of wind next to you and as it swirls, it will pick up dust from the ground, creating a perfect defense against thing like kunais and shurikens

Description: The user creates a gust of wind that layers an area in loose sand and dust. Doing so also acts as a sandblaster on the surrounding area.

The initial gust can also temporarily blind opponents by lodging sand in their eyes
