Hydrology - Flowrate vs. radius of influence I am using the following equation (Theim/Dupuit) to determine radius of influence for an unconfined aquifer. 


Assume all other variables are held constant. If Q increases, does the Radius of influence R2 also increase?
I think your confusion is because you are keeping the head fixed. As you increase Q at fixed T the drawdown curve will become steeper when r1, h1, and h2 are fixed. That means r2 will move towards the pumping well.
