Hi all,

I've got the following Maple math code (its called the 'Strickler function', giving a relation between water hight 'y' in a channel and other paramaters), that works like a charm and correctly outputs my function Q =

> restart;
> A := (b+m*y)*y;
> R := A/(b+2*y*sqrt(1+m^2));
> Q := k*A*R^(2/3)*s^(1/2);

However, all contants in the functions are know, except for 'y' (Q is known as well). How do I solve the last equation for...
