Short summary
This is the first modeling study of conduit network evolution in karst aquifers under pressurized and free surface turbulent flow conditions. Under pressurized flow, the evolution is governed by the feedback between the distribution of hydraulic head and the growth of conduits, as has been already revealed by earlier models. We demonstrate the final selection of stable flow paths on the scale of individual junctions, during and after transition to the free-surface flow regime.
