Hydraulic conductivity is a key parameter governing groundwater flow processes. In this work, hydraulic conductivity was upscaled with the objective of assessing the optimal value of the p-power parameter (of the power averaging upscaling approach) that minimizes the discrepancy between the capillary pressure calculated with fine hydraulic conductivity fields, and the capillary pressure computed with upscaled fields in a two-dimensional unsaturated infiltration problem. The analyses were framed in a probabilistic context, where hydraulic conductivity is conceptualized as a random process in space. Values of p in the interval [-1,1] to scale the hydraulic conductivity under four different infiltration rates were tested. Gaussian and no...
