Question: Problem to plot a difficult graph

Hello all,

For a project of groundwater contaminations i need to plot the following graph.

18^2-y^2 = Q*(ln((3000*(18-y))*sqrt(0.412e-4))-ln(sqrt(x)))/(0.412e-4*Pi)

where as X stands for the distance of a waterfilter and Y stands for the water level.

I tried to plot this with maple but i cant find the solution for this.


Thanks for your time,
