In granular porous media, this secondary drainage mechanism unfolds in connected pathways of pendular structures, such as capillary bridges and liquid rings, formed between liquid clusters. To represent both mechanisms, we proposed a dynamic dual-network model for drainage, considering that a gas displaces a wetting liquid from quasi-2D granular porous media. For this model, dedicated analyses of the capillary bridge shapes and hydraulic conductivity were conducted so that the secondary drainage mechanism could be properly quantified at finite speeds. With the model, an investigation of the wetting-phase connectivity and flow during drainage was carried out, covering a broad range of flow conditions.

A variable injection rate (such as ramping the flow rate up or down) provides flexibility to injection sites, and could influence the amount of residual trapping. Observations made in cm-scale samples showed that starting at a low flow rate established a flow pathway across the core at a low capillary pressure, leading to a long-term reduction in pore space utilization, as increases in flux were accommodated with little change in saturation. In this work, the scalability of these observations is evaluated by performing experiments with variable injection rates in larger samples: 5 cm diameter and 12 cm length, compared to 2.5 cm diameter and 4.5 cm length in previous work (<span><span>Spurin et al., 2024</span></span>). We observed that starting at a low flow rate did not lead to a long-term reduction in pore space utilization. Instead, saturation increased significantly with increased flux, leading to a higher pore space utilization than experiments where injection started with the higher flow rate.

Gravity, Darcian resistance of the soil at full saturation but negative pressure, and capillarity are three physical competing factors involved through the Vedernikov-Bouwer analytical model, which assumes 2-D, tension-saturated flow in a homogeneous soil sandwiched between the free surfaces (capillary fringe boundaries) and Kornev's impermeable liner of the ditch. Water seeps up from a line source, <em>viz</em>. a zero-pressure segment such that everywhere in the flow domain pressure remains negative. Lining minimizes deep percolation and facilitates upward and lateral spread of pore water by soil's capillarity. The free surfaces are streamlines, along which the pressure head is a negative constant (the air entrance pressure head, soil's property). For a small-depth ditch the hodograph domain is either a circular trigone, tetragon or sextagon, that determines three different flow topologies (with J.R.Philip's “dry shadow”, “dry bulb” and no dry zone at all on the leeward side of the liner and “wet lobes” hanging on the edge of the liner).

Additionally, at the valleys, there is an accumulation of the solute and a thickening of the boundary layer caused by the recirculation which induces the nucleation and by the anchoring of the fingering process at that location. This anchoring is maintained up to the later shutdown stages for cases with large interface undulations.
