Ok, so I am trying to solve this equasion for y

0.33392=(1/0.027)*(y+2*y^2)*((y+2*y^2)/(2.236+4.472*y))^(2/3)

I should probably know how to do this myself (I've done a million and one math courses over the past 5 years :P) but I would rather get a refresher from one of you guys/gals

The problem involves trying to find the height of water in an open channel given the rate of flow and channel cross section. y is the height of water in question.

Thanks!
