“…This field was linearly scaled to represent spatially varying fields of van Genuchten () parameters α (between 0.005 and 0.02 cm −1 ) and n ′ (between 1 and 2) over a 55‐m‐long and 4‐m‐in depth grid, with 0.2 × 0.2 m 2 grid cells size. These parameters and synthetic survey size are comparable to those of our site (Dietrich et al, ). Using these parameters we computed soil water contents for two water table positions, 1.5 and 2.6 m below surface assuming a residual saturation of 0.15 and a porosity of 0.45 (Figures a and b, the actual water content values are available in the supporting information).…”

“…Electrical resistivity tomography (ERT), which measures the spatial distribution of subsurface resistivity, has emerged as a useful geophysical tool for studying the subsurface and tracking hydrologic processes. Due to the general tendency of decreasing resistivity with increasing water content, ERT has commonly been used in a time-lapse capacity to monitor infiltration processes at the event scale (Batlle-Aguilar et al, 2009;Dietrich, Weinzettel, & Varni, 2014;Michot et al, 2003) and seasonal moisture fluctuations (French & Binley, 2004;Jayawickreme, Van Dam, & Hyndman, 2008;Kotikian, Parsekian, Paige, & Carey, 2018;Schwartz, Schreiber, & Yan, 2008;Thayer et al, 2018). Other geophysical tools such as seismic refraction and ground-penetrating radar (GPR) can provide valuable information regarding subsurface structure (Holbrook et al, 2014;McClymont, Hayashi, Bentley, & Liard, 2012;Mills, 1990;Neal, 2004;Parsekian, Singha, Minsley, Holbrook, & Slater, 2015).…”

“…Por otro lado, también es relevante considerar la presencia de horizontes en el perfil del suelo que dificultan la infiltración de agua y la penetración de las raíces, como lo son horizontes argílicos y petrocálcicos (Mujica y Bea, 2020;Mujica et al, 2019aMujica et al, , 2019bPazos y Mestelan, 2002) o roca. La presencia de estos horizontes podrían dificultar el acceso de la forestación al acuífero freático o el flujo del agua hacia la rizósfera, limitando así la acumulación de sales en el sistema (Mujica et al, 2019a(Mujica et al, , 2019bDietrich et al, 2014;Jobbágy and Jackson, 2004a;Shreve and Mallery, 1933).…”

“…En muchos ambientes de llanura alrededor del mundo, incluida la región pampeana, existe la presencia de horizontes petrocálcicos a diferentes profundidades, espesores, y grados de cementación (Figura 3-1 y Figura 3-2; Duniway, Herrick, & Monger, 2010;Pazos & Mestelan, 2002). En muchos casos, estos horizontes son considerados una barrera para el desarrollo de las raíces y el flujo de agua (Dietrich et al, 2014;Shreve y Mallery, 1933). Sin embargo, cómo impacta su presencia en la dinámica de los flujos de agua, y aquella almacenada disponible para consumo de las plantas (Plant Available Water, ), han sido poco estudiados (Duniway et al, 2007(Duniway et al, , 2010.…”
