Complex Modeling, Flow From Penetrated Probe


I am attempting to model flow coming out of a probe laterally, which is driven underground. The model itself doesn't need to be during the driving phase, just how the flow leaves the flow laterally and how/ where it flows into the adjacent soil. A comparison would be modeling a borehole infiltration test, however, the flow would be lateral instead of vertical. I was also wondering what the best way to model this test was, I couldn't find any examples.

If anyone has some ideas on the best way to model these two scenarios in PLAXIS 2D, please let me know!
