Technical note: Saturated hydraulic conductivity and textural heterogeneity of soils

Characterization of field saturated hydraulic conductivity

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract In the context of studies aiming at the estimation of effective parameters for unsaturated zone modelling, this work tackles the problem of experimental data quality, considering the large collection of data gathered at an experimental sit...

Saturated Hydraulic Conductivity of Semiarid Soils: Combined Effects of Salinity, Sodicity, and Rate of Wetting

als, high pH, and low sesquioxides content was found to be susceptible to sodic conditions, with the magnitude Combined effects of soil conditions (wetting rate), soil sodicity, of the decrease in HC being strongly dependent on the and salinity on soil saturated hydraulic conductivity (HC) have not been studied systematically and were the objective of our study. We electrolyte concentration in ...

Influence of Anionic Surfactant on Saturated Hydraulic Conductivity of Loamy Sand and Sandy Loam Soils

Surfactants released into the terrestrial environment in large amounts can potentially alter the physical, chemical and biological properties of soils, particularly the saturated hydraulic conductivity (Ks). Unfortunately findings regarding this process are quite limited. In this study, column tests were used to analyze the effects of Aerosol 22, a widely used anionic surfactant, on Ks of loamy...

Evaluation of two methods for measuring saturated hydraulic conductivity of soils under two vegetation covers

The main goal of this work is to determine and to evaluate the saturated hydraulic conductivity for a silt loam soil in field and laboratory conditions. The experimental area was located in the Vallcebre research catchments, in headwaters of the Llobregat River (NE Spain). Hydraulic conductivity was measured in the field using the Guelph permeameter and field saturated hydraulic conductivity (K...
