“…A micro‐infiltrometer (Soracco et al., 2019) was used in order to determine water infiltration under different water pressure heads in the air‐dried undisturbed soil samples. The device consisted of a tube with a 1‐cm‐radius disc, with a membrane of the same material as the commercial tension disc infiltrometer (Perroux & White, 1988) attached to its base.…”

“…In the last years, several authors have mentioned a decrease of soil physical quality in the Pampas region related to simplified crop rotations, including soybean [Glycine max (L.) Merr.] monoculture, with long bare fallow periods during winter and low supply of harvest residues (C. R. Alvarez et al, 2009;Ferreras et al, 2000;Lozano et al, 2013;Sasal et al, 2006;Soracco et al, 2010Soracco et al, , 2019 In general, diversifying the crop sequences and increasing the time with living crops have shown positive effects in soil quality, increasing aggregate stability (Behrends Kraemer et al, 2021;Novelli et al, 2013) and organic carbon content (Duval et al, 2016). However, there are contrasting results about the effects of crop diversification on soil hydraulic properties.…”

Decreasing physical quality of Mollisols in the Argentinean Pampas region is observed due to simplified crop rotations. The main objective of this work was to evaluate the effects of cover cropping management on soil water capture, transport, and storage as compared with different crop rotations with bare fallow in two different and representative Mollisols of the Argentinean Pampas region (one Typic Argiudoll [TA] and one Typic Hapludoll [TH]). Water capture, transport, and storage processes were assessed through soil sorptivity, infiltration tests at different pressures heads, and soil water retention curve determination. In addition, aggregate stability and soil organic carbon (SOC) were determined and the relationship between studied variables and processes was evaluated. It was observed that soybean [Glycine max (L.) Merr.] monocultures jeopardize Mollisols conservation, decreasing water capture and transport and SOC content. The inclusion of cover cropping management increased the soil water transport in the TA and water capture in the TH, as compared with bare fallow rotations. In this sense, our results show that cover cropping could be a suitable management in order to recover degraded soils due to simplified crop rotations in Mollisols from the Argentina Pampas region.

“…Los altos valores de infiltración en estas dos zonas pueden estar relacionados a diferentes elementos, para la zona 2, los valores de fc, relacionados a la conductividad hidráulica, son los más altos para toda la cuenca alta del río Páez y están asociados a una mayor entrada de agua al suelo en un menor tiempo, para la zona 5, los mayores valores de infiltración están asociados a los mayores valores retención de humedad de la cuenca alta, este aspecto ha sido mostrado por otros autores (Castiglion et al, 2018) y lo cual ocurre por la conectividad de los poros (Soracco et al, 2019) específicamente aquellos macroporos hidráulicamente activos. Para las zonas de infiltración 2 y 5, el período de infiltración inicia a partir de mayo para el mes de mayor tanto para los eventos de Niño y Neutro, y un mes antes en el mes de abril para Niña.…”

Se presentan los resultados de la aplicación de un modelo analítico para el cálculo de la infiltración del agua de lluvia mensual a escala de cuenca hidrográfica. El modelado analítico de la infiltración fue realizado a partir del método de Schosinsky. Para la aplicación del modelo se analizaron los datos de precipitación mensual de un período de 20 años de acuerdo con distintos eventos climáticos, Niña, Niño y Neutro, las propiedades geomorfométricas del terreno, la dinámica del uso y la cobertura de la tierra y las propiedades físicas e hidráulicas de los suelos volcánicos en la cuenca hidrográfica del río Páez. Una vez ejecutado el análisis de estas variables, se establecieron zonas específicas en la cuenca las cuales fueron objeto de la aplicación del cálculo analítico de infiltración. Los resultados mostraron que la lluvia condiciona la entrada de agua por infiltración y que además está en función del evento climático que se pueda presentar mes a mes durante una serie de 20 años, además la entrada de agua una vez que alcanza el suelo, varía de acuerdo con las condiciones de pendiente del terreno, la condición de la cobertura o el uso de la tierra y los tipos de propiedades físicas e hidráulicas de los suelos en función de los subórdenes de suelos existentes. La aplicación del modelo de Schosinsky permitió la zonificación de la cuenca en áreas de infiltración específicas, las cuales presentaron distintos rangos de infiltración según los eventos climáticos que se den. Este trabajo demostró la aplicabilidad del modelo de Schosinsky para la determinación de la infiltración a escala de cuenca hidrográfica y la ventaja que éste tiene de poder mejorar su cálculo de acuerdo con el detalle de la información que se obtenga.

“…In general, more connected soil macropores probably contribute to the smooth of water flow (Rezanezhad et al 2009 ). High soil macropores connectivity is possibly caused by good soil structures and well established biological activity (Wu et al 2017 ; Soracco et al 2019 ). Root channels can contribute more to the high soil macropores connectivity (Hu et al 2019b ).…”

In this review, we explore the concept, approach, and future research of hydrological connectivity and its assessment at multiscales, because according to the literature, an integrated review upon hydrological connectivity is lack. Systematic studies illustrate the effects of (i) human activities (i.e., dam construction, groundwater extraction, water flow regulation and diversion, and land management) and (ii) natural factors (i.e., climate, soil characteristics, vegetation, and topography) on hydrological connectivity. Approaches (i.e., soil water content patterns, runoff patterns and processes, numerical models, and index of hydrological connectivity) applied to evaluate hydrological connectivity are examined in detail. Lastly, hydrological connectivity at multiscales is indicated. This review concludes with a discussion of potential research trends that can improve understanding of hydrological connectivity. Reported records showed that few studies were published on hydrological connectivity from 1980 to 2003, whereas the evolution of these studies is temporally promising since 2003. We cannot define a standard concept of hydrological connectivity that works in all environments. We desire to show different concepts of hydrological connectivity in different environments. The degree and nature of hydrological connectivity are not static due to the influences of human activities and changes of natural factors. The index of hydrological connectivity and numerical models are the most significant approaches to assess the changes in hydrological connectivity. This study showed that considering hydrological connectivity in social-economical-ecological-hydrological frameworks can prevent its negative effects on surface or subsurface water quantity and quality and is beneficial for sound water sources management.
