Using DFEs in axisymmetric projection

Hello,

I'm modeling the disposal of saline wastewater in a deep, confined aquifer that is 50 m thick. I plan on using an axisymmetric projection and having the disposal well located along the entire length of the left-hand side of the model. I would like to simulate the well using a discrete feature, but am having some difficulty understanding some of the parameters (and how they should be determined given the projection type), specifically Thickness and Hydraulic Aperture (using the Hagen-Poiseuille setting).

Would anyone be able to shed some light on this, or point me towards some resources on the topic?

Thanks

Why you want to use Discrete Features (DF's) in an axisymmetric projection?

You could also use a Neumann BC and calculate the corresponding q value according to the pumping rate Q, filter section B, radius R (see attachment).
